What is `Hoardy-Web`?

Hoardy-Web is a suite of tools that helps you to passively capture, archive, and hoard your web browsing history. Not just the URLs, but also the contents and the requisite resources (images, media, CSS, fonts, etc) of the pages you visit. Not just the last 3 months, but from the beginning of time you start using it.

Practically speaking, you install the Hoardy-Web browser extension/add-on into your web browser and just browse the web normally while Hoardy-Web passively, in background, captures and archives web pages you visit for later offline viewing, mirroring, and/or indexing.

Note that Hoardy-Web's browser extension

can be used independently of other tools that are being developed in this repository, so you can install it and start saving your browsing history immediately, and then delay learning to use the rest of the tools developed here for later;
has a lot of configuration options to help you tweak what should or should not be archived and a very low memory footprint, keeping you browsing experience snappy even on ancient hardware (unless you explicitly configure it to do otherwise to, e.g., minimize writes to disk instead).

To view/replay your archived data you will need to install at least the accompanying hoardy-web tool which can

replay your archives over HTTP (a-la a local Wayback Machine),
generate static website mirrors from it (a-la wget -mpk),
search, inspect, organize, manipulate, programmatically extract values from, and run scripts over your collected data.

See the next section for a little storyboard explaining the above with pictures.

These two sections of the Help page answer questions about most common issues you can encounter while using Hoardy-Web extension/add-on.
See the "Quickstart" section for setup instructions.

Hoardy-Web was previously known as "Personal Private Passive Web Archive" aka "pwebarc".

If you are reading this on GitHub, be aware that this repository is a mirror of a repository on the author's web site. In author's humble opinion, the rendering of the documentation pages there is superior to what can be seen on GitHub (its implemented via pandoc there).

Storyboarded screenshots

So, for illustrative purposes, I installed the Hoardy-Web extension, installed and started a hoardy-web serve archiving server instance, switched the extension to Submit dumps via 'HTTP' mode (like this screenshot shows, on the P&R tab; also, I ensured that Server URL there points to my hoardy-web serve instance, but it's the default), and then visited a Wikipedia page:

Also note that I had enabled limbo mode before visiting it so that I could first look at the page before deciding if I want to archive it. (This is most useful for dynamically generated pages that update all the time with only some versions deserving being archived.) So, then, I decided I do want to save it. Hence, I pressed the lower of "In limbo" check-mark buttons there to collect and archive everything from that tab to my hoardy-web serve archiving server instance.

Then, I pressed the "Replay" button to switch to a replay page generated by hoardy-web serve for the above capture:

... and closed the browser.

Then, later, I reopened it, restored the last session, and that tab was restored back with zero requests to the Internet.

See the screenshot gallery for more screenshots, including those with Hoardy-Web running on Chromium and those showing off how nice and feature-rich the Help page becomes when you look at it by pressing the "Help" button in extension's UI.

Supported use cases

For a layman user

Regular users are expected to capture data using the Hoardy-Web browser extension/add-on, producing HTTP request+response dumps in WRR file format, archive those to disk using one of the supported methods, and then use various sub-command of the hoardy-web tool to

replay (a subset of) your archives over HTTP by feeding them to hoardy-web serve and then using a normal web browser and navigating to links like http://127.0.0.1:3210/web/2/https://archiveofourown.org/works/3733123;

this is similar to what Wayback Machine, heritrix, and pywb do;
generate a static offline website mirror from (a subset of) your archives by feeding them to hoardy-web mirror to produce a bunch of interlinked HTML, CSS, images, and other files, which you can then view using a normal web browser, or with a e-book reader, or you can instead feed them to recoll or some other desktop search engine, etc;

this is similar to what wget -mpk (wget --mirror --page-requisites --convert-links) does, except hoardy-web mirror has a ton of cool options wget does not (e.g. it can scrub generated pages in various ways, de-duplicate the files it generates, including between different websites and different generated mirrors, etc), and should you discover you dislike the generated result for some reason, you can change some or all of those options and re-generate the mirror without re-downloading anything.

See hoardy-web's "Quickstart" section for more info.

For a slightly technical user

Users that want to get more out of their archives and are not afraid of the command-line interface, can use

hoardy-web find to find a subset of archives matching a specified criteria or
hoardy-web organize to instead maintain a tree of symlinks pointing to each or latest archive matching a specified criteria (e.g., maintain a tree of per-domain pointers to the latest visit to each URL, or links to all ever archived images, or PDF files, etc)

and then use one of the ready-made scripts on the results to, e.g.,

view HTML documents via pandoc piped into less in your favorite tty emulator,
listen their contents with a TTS engine via spd-say,
open files stored inside WRR dumps via xdg-open (so, e.g., you can view images stored inside without first running hoardy-web mirror),
etc.

For a technical user

Alternatively, you can use the hoardy-web get sub-command of the hoardy-web tool to make your own scripts for processing archived web pages and files in arbitrary ways, similarly to the ready-made scripts.

Or, you can programmatically extract values from large subsets of your data by using the hoardy-web stream sub-command to filter and map your captures with pre-defined filters and functions, or with your own custom code, and thus produce streams of interesting values in a raw textual format, and/or as structured JSON and/or CBOR (RFC8949) values, which you can then pipe somewhere else.

This, for instance, allows you to easily query things like "get me a list of domains that ever used CloudFlare when I visited them", or anything else you can imagine.

Or, you can use hoardy-web find to find paths of files matching a specified criteria and then just dump those into JSONs, or parse the original CBOR-formatted WRR files yourself with readily-available libraries.

Since the whole of the Hoardy-Web project adheres to the philosophy described below, the simultaneous use of the Hoardy-Web extension and the hoardy-web tool helps immensely when developing scrapers for uncooperative websites: you just visit them via your web browser as normal, then, possibly years later, use the hoardy-web tool to organize your archives and conveniently programmatically feed the archived data into your scraper without the need to re-fetch anything.

Given how simple the WRR file format is, you can modify any HTTP library to generate WRR files, thus allowing you to use the hoardy-web tool with data captured by other software, and use data produced by the Hoardy-Web extension as inputs to your own tools.

Which is why, personally, I patch some of the commonly available FLOSS website scrapers to dump the data they fetch as WRR files so that in the future I could write my own better scrapers and indexers and test them on a huge collected database of already collected inputs immediately.

Also, as far as I'm aware, hoardy-web is a tool that can do more useful stuff to your WRR archives than any other tool can do to any other file format for HTTP dumps with the sole exception of WARC.

Why does `Hoardy-Web` exists?

For a layman user

So, you wake up remembering something interesting you saw a long time ago. Knowing you won't find it in your normal browsing history, which only contains the URLs and the titles of the pages you visited in the last 3 months, you try looking it up on Google. You fail. Eventually, you remember the website you seen it at, or maybe you re-discovered the link in question in an old message to/from a friend, or maybe a tool like recoll or Promnesia helped you. You open the link… and discover it offline/gone/a parked domain. Not a problem! Have no fear! You go to Wayback Machine and look it up there… and discover they only archived an ancient version of it and the thing you wanted is missing there.

Or, say, you read a cool fanfiction on AO3 years ago, you even wrote down the URL, you go back to it wanting to experience it again… and discover the author made it private... and Wayback Machine saved only the very first chapter.

"If it is on the Internet, it is on Internet forever!" they said. They lied!

Things vanish from the Internet all the time, Wayback Machine of the Internet Archive is awesome, but

you need to be online to use it,
it has no full-text search (some of their database can be searched, but not all, this is probably a privacy feature by this point),
they only archive a subset of the public web, and only what can be reached with HTTP GET requests,
a website you might want archived might be banned by the Wayback Machine,
or the website might ban Wayback Machine's crawler instead,
and they appear to remove/hide already archived data when threatened by policy makers and/or lawsuits.

(On that latter point, you should probably go and donate to the Internet Archive to help them fight it.)

Meanwhile, Hoardy-Web solves all of the above issues for the pages you visited before.

For a user with accessibility or comfort requirements

Say, there is a web page that can not be easily reached via curl/wget (because it is behind a paywall or complex authentication method that is hard to reproduce outside of a browser) but for accessibility or just simple reading comfort reasons each time you visit that page you want to automatically feed its source to a script that strips and/or modifies its HTML markup in a website-specific way and feeds it into a TTS engine, a Braille display, or a book reader app.

With most modern web browsers you can do TTS either out-of-the-box or by installing an add-on (though, be aware of privacy issues when using most of these), but tools that can do website-specific accessibility without also being website-specific UI apps are very few.

Meanwhile, Hoardy-Web with some scripts can do it.

For a technical user

Say, there's a web page/app you use (like a banking app), but it lacks some features you want, and in your browser's Network Monitor you can see it uses JSON RPC or some such to fetch its data, and you want those JSONs for yourself (e.g., to compute statistics and supplement the app output with them), but the app in question has no public API and scraping it with a script is non-trivial (e.g., the site does complicated JavaScript+multifactor-based auth, tries to detect you are actually using a browser, and bans you immediately if not).

Or, maybe, you want to parse those behind-auth pages with a script, save the results to a database, and then do interesting things with them (e.g., track price changes, manually classify, annotate, and merge pages representing the same product by different sellers, do complex queries, like sorting by price/unit or price/weight, limit results by geographical locations extracted from text labels, etc).

Or, say, you want to fetch a bunch of pages belonging to two recommendation lists on AO3 or GoodReads, get all outgoing links for each fetched page, union sets for the pages belonging to the same recommendation list, and then intersect the results of the two lists to get a shorter list of things you might want to read with higher probability.

Or, more generally, say, you want to tag web pages referenced from a certain set of other web pages with some tag in your indexing software, and update it automatically each time you visit any of the source pages.

Or, say, you want to combine a full-text indexing engine, your browsing and derived web link graph data, your states/ratings/notes from org-mode, messages from your friends, and other archives, so that you could do arbitrarily complex queries over it all, like "show me all GoodReads pages for all books not marked as DONE or CANCELED in my org-mode files, ever mentioned by any of my friends, ordered by undirected-graph Pagerank algorithm biased with my own book ratings (so that books sharing GoodReads lists with the books I finished and liked will get higher scores)". So, basically, you want a private personalized Bayesian recommendation system.

"Everything will have a RESTful API!" they said. They lied! A lot of useful stuff never got RESTful APIs, those RESTful APIs that exists are frequently buggy, you'll probably have to scrape data from HTMLs anyway.

"Semantic Web will allow arbitrarily complex queries spanning multiple data sources!" they said. Well, 25 years later ("RDF Model and Syntax Specification" was published in 1999), almost no progress there, the most commonly used subset of RDF does what indexing systems in 1970s did, but less efficiently and with a worse UI.

Meanwhile, Hoardy-Web provides some of the tools to help you build your own little local data paradise.

Highlights

The Hoardy-Web browser extension runs under desktop versions of both Firefox- and Chromium-based browsers as well as under Firefox-for-Android-based browsers.

Hoardy-Web's main workflow is to passively collect and archive HTTP requests and responses (and, if you ask, also DOM snapshots, i.e. the contents of the page after all JavaScript was run) directly from your browser as you browse the web.

Therefore, the extension allows you to

trivially archive web pages hidden behind CAPTCHAs, requiring special cookies, multi-factor logins, paywalls, anti-scraping/curl/wget measures, and etc (after all, the website in question only interacts with your normal web browser, not with a custom web crawler);
archive most HTTP-level data, not just web pages, and not just things available via HTTP GET requests (e.g., it can archive answer pages of web search engines fetched via HTTP POST, AJAX data, JSON RPC calls, etc; though, at the moment, it can not archive WebSockets data);

all the while

being invisible to websites you are browsing;
downloading everything only once, not once with your browser and then the second time with a separate tool like ArchiveBox (or with an extension like SingleFile, which can re-download some invalidated cached data when you ask it to save a page);
freeing you from worries of forgetting to archive something because you forgot to press a button somewhere.

The extension can archive collected data

into browser's local storage (the default),
into files saved to your local file system (by generating fake-Downloads containing bundles of WRR-formatted dumps),
to a self-hosted archiving server (like the trivial archival-only hoardy-web-sas or the more advanced archival+replay hoardy-web serve),
any combination of the above.

Also, unless configured otherwise, the extension will dump and archive collected data immediately, to both prevent data loss and to free the used RAM as soon as possible, keeping your browsing experience snappy even on ancient hardware.

You can then view your archived data with some help from the hoardy-web tool by

replaying your archives over HTTP, similar to Wayback Machine, heritrix, and pywb;
generating local offline static website mirrors, similar to what wget does;
using one of the ready-made scripts; or
making you own scripts built on top of hoardy-web.

Hoardy-Web allows you to search your archives

directly from hoardy-web serve by using glob-URL links like http://127.0.0.1:3210/web/*/https://archiveofourown.org/works/[0-9]*, a-la Wayback Machine;
via hoardy-web find.

(The latter option can also do full-text search via the --*grep* options, but, at the moment, it's rather slow since there is no built-in full-text indexing. You can, however, full-text index you data by hoardy-web mirroring it first and then feeding the result to an arbitrary desktop search engine, or by using hoardy-web get as a filter for recoll.)

In other words, Hoardy-Web is your own personal private Wayback Machine which passively archives everything you see. However, unlike the original Wayback Machine, it also

archives HTTP POST requests and responses, and most other HTTP-level data,
makes other uses other than the conventional browser-only reading-only workflow pretty easy.

In short, compared to most of its alternatives, Hoardy-Web DOES NOT:

force you to use a Chromium-based browser (you can use Hoardy-Web with Firefox, Tor Browser, LibreWolf, Fenix aka Firefox for Android, Fennec, Mull, etc, which is not a small thing, since if you tried using any of the close alternatives running under Chromium-based browsers, you might have noticed that the experience there is pretty awful: the browser becomes even slower than usual, large files don't get captured, random stuff fails to be captured at random times because Chromium randomly detaches its debugger from its tabs... none of these problems exist on Firefox-based browsers because Firefox does not fight ad-blocking and hardcore ad-blocking extensions and Hoardy-Web use the same browser APIs);
require you to capture, collect, and archive recorded data one page/browsing session at a time (the default behaviour is to archive everything completely automatically, though it implements optional limbo mode which delays archival of collected data and provides optional manual/semi-automatic control if you want it);
require you to download the data you want to archive twice or more (you'd be surprised how commonly other tools will either ask you to do that explicitly, or just do that silently when you ask them to save something);
send any of your data anywhere (unless you explicitly configure it to do so);
send any telemetry anywhere;
require you to store all the things in browser's local storage where they can vanish at any moment (though, saving to local storage is the default because it simplifies on-boarding, but switching to another archival method takes a couple of clicks and re-archival of old data from browser's local storage to elsewhere is easy);
require you to run a database server;
require you to run a web browser to view the data you've already archived.

Technically, the Hoardy-Web project is most similar to

DownloadNet project, but with collection, archival, and replay all (optionally) independent from each other, with an advanced command-line interface, and not limited to Chromium;
mitmproxy project, but Hoardy-Web leaves SSL/TLS layer alone and hooks into browser's runtime instead, and its tooling is designed primarily for web archival purposes, not traffic inspection and protocol reverse-engineering;
archiveweb.page project, but following "capture and archive everything with as little user input as needed now, figure out what to do with it later" philosophy, and also not limited to Chromium;
pywb project, but with collection, archival, and replay all (optionally) independent from each other, with a simpler web interface, and more advanced command-line interface.

In fact, an unpublished and now irrelevant ancestor project of Hoardy-Web was a tool to generate website mirrors from mitmproxy stream captures. (If you want that, hoardy-web tool can do that for you. It can take mitmproxy dumps as inputs.) But then I got annoyed by all the sites that don't work under mitmproxy, did some research into the alternatives, decided there were none I wanted to use, and so I started adding stuff to my tool until it became Hoardy-Web.

For more info see the list of comparisons to alternatives.

Parts and pieces

Required

The Hoardy-Web browser extension that captures all HTTP requests and responses (and DOM snapshots) your browser fetches, dumps them into WRR format, and then exports them by generating fake-Downloads containing bundles of those dumps, submits them to the specified archiving server (by POSTing them to the specified URL), or saves the to browser's local storage.

The extension is
- stable while running under desktop versions of both Firefox- and Chromium-based browsers;
- beta while running under Fenix-based (Firefox-for-Android-based) browsers.
See the "Quirks and Bugs" section of extension's Help page for known issues. Also, Hoardy-Web is tested much less on Chromium than on Firefox.

Optional, but convenient

The hoardy-web-sas simple archiving server that simply dumps everything the Hoardy-Web extension submits to it to disk, one file per HTTP request+response.

This is only useful if you did not yet install the full-featured hoardy-web tool. Or if you are feeling paranoid and you want archival and replay to be done by separate processes.

The simple archiving server is stable (it's so simple there hardly could be any bugs there).

Optional, but almost always required at some point

The hoardy-web tool, to quote from there:

hoardy-web is a tool to inspect, search, organize, programmatically extract values and generate static website mirrors from, archive, view, and replay HTTP archives/dumps in WRR ("Web Request+Response", produced by the Hoardy-Web Web Extension browser add-on, also there) and mitmproxy (mitmdump) file formats.

That is, yes, it can also play the role of an advanced archiving server with replay support for the Hoardy-Web browser extension instead of the basic archiving server the hoardy-web-sas script is.

hoardy-web tool is deep in its beta stage. At the moment, it does about 85% of the stuff I want it to do, and the things it does it does not do as well as I'd like. See the TODO list for more info.

Optional, but useful

A patch for Firefox to allow Hoardy-Web extension to collect request POST data as-is. This is not required and even without that patch Hoardy-Web will collect everything in most cases, but it could be useful if you want to correctly capture POST requests that upload files.

See the "Quirks and Bugs" section of extension's Help page for more info.

Technical Philosophy

Hoardy-Web is designed to

be simple (as in adhering to the Keep It Stupid Simple principle),
be efficient (as in running well on ancient hardware),
capture data from the browser as raw as possible (i.e., not try to fix any web browser quirks before archival, just capture everything as-is),
ensure that all captured and collected data gets actually archived to disk,
treat the resulting archives as read-only files,
view, convert to other formats, extract useful values, and perform any expensive computations lazily and on-demand,
make it easy to use tools other than a web browser to do interesting things with your archived data.

To conform to the above design principles

the Hoardy-Web Web Extension browser add-on does almost no actual work, simply generating HTTP request+response dumps, archiving them, and then freeing the memory as soon as possible (unless you enable limbo mode, but then you asked for it), thus keeping your browsing experience snappy even on ancient hardware;
also the Hoardy-Web extension collects data as browser gives it, without any data normalization and conversion, when possible;
the dumps are generated using the simplest, trivially parsable with many third-party libraries, yet most space-efficient on-disk file format representing separate HTTP requests+responses there currently is (aka Web Request+Response, WRR), which is a file format that is both more general and more simple than WARC, much simpler than that mitmproxy uses, and much more efficient than HAR;
the Hoardy-Web extension can write the dumps it produces to disk by itself by generating fake-Dowloads containing bundles of WRR dumps, but because of limitations of browser APIs, Hoardy-Web can't tell if a file generated this way succeeds at being written to disk;
which is why, for users who want write guarantees and error reporting, the extension has other archival methods, which includes archival by submission via HTTP;

server-side part of submission via HTTP can be done either
- via the hoardy-web-sas simple archiving server, which is tiny (less than 250 lines of code) pure-Python script that provides an HTTP interface for archival of dumps given via HTTP POST requests;
- or via the hoardy-web serve, which is not tiny at all, but it can combine both archival and replay;
all of the Hoardy-Web extension, hoardy-web-sas, and hoardy-web serve write those dumps to disk as-is, with optional compression for data storage efficiency;
meanwhile, viewing/replay of, generation of website mirrors from, organization and management, data normalization (massaging), post-processing, other ways of extraction of useful values from archived WRR files --- i.e. basically everything that is complex and/or computationally expensive --- is delegated to hoardy-web tool;
the hoardy-web tool is very easy to use in your own scripts;
by default, none these tools ever overwrite any files on disk (to prevent accidental data loss);

this way, if something breaks, you can always trivially return to a known-good state by simply copying some old files from a backup as there's no need to track versions or anything like that.

What does it do, exactly? I have questions.

See extension's Help page (or the Help button in the extension's UI, which will make it interactive) for a long detailed description of what the extension does step-by-step.

It is a must-read, though instead of reading that file raw I highly recommend you read it via the Help button of the extension's UI, since doing that will make the whole thing pretty interactive.
- See the "Frequently Asked Questions" section of extension's Help page for the answers to the frequently asked questions, including those about common quirks you can encounter while using it.
- See the "Quirks and Bugs" section of extension's Help page for more info on quirks and limitations of Hoardy-Web when used on different browsers.
See below for a long list of comparisons to its alternatives.

- Also, a lot of info from that page can be seen by running hoardy-web --help.
- See example scripts to learn how to do various interesting things with your archived data.
In the unlikely case you have problems with the hoardy-web-sas simple archiving server, see its README. Or you can read hoardy-web-sas --help instead.
If you want to build the extension from source, see its README.
If you are a developer, see all the hoardy-web-related links above, and also see the description of the on-disk file format used by all these tools.
If your questions are not unanswered by these, then open an issue on GitHub or get in touch otherwise.

Does the author eat what he cooks?

Yes, as of December 2024, I archive all of my web traffic using Hoardy-Web, without any interruptions, since October 2023. Before that my preferred tool was mitmproxy.

After adding each new feature to the hoardy-web tool, as a rule, I feed at least the last 5 years of my web browsing into it (at the moment, most of it converted from other formats to .wrr, obviously) to see if everything works as expected.

Quickstart

Install `Hoardy-Web` browser extension/add-on

On Firefox, Tor Browser, LibreWolf, Fenix aka Firefox for Android, Fennec, Mull, etc: Install the extension from addons.mozilla.org.
On Chromium, Google Chrome, Ungoogled Chromium, Brave, etc: see Installing on Chromium-based browser.

Unfortunately, this requires a bit more work than clicking Install button on Chrome Web Store, yes. "Why isn't Hoardy-Web on Chrome Web Store?" I'm not a lawyer, but to me it looks like Hoardy-Web violates Chrome Web Store's "Terms of Use". Specifically, the "enables the unauthorized download of streaming content or media" clause.

In my personal opinion, any content you web browser fetches while you are browsing the web normally you are "authorized" to download. This is especially true for Hoardy-Web since, unlike most of its alternatives, it does not generate any requests itself, it only captures the data that a web page generates while you browse it. But given the context of that clause in that document, I feel like Google would disagree with my the interpretation above. Even though, technically speaking, separation between "streamed" and "downloaded" content or media is a complete delusion.

Meanwhile, Hoardy-Web tries its best to collect all web traffic you browser generates, which, obviously, includes streaming content.

On Chromium (but not on Firefox), technically, at the moment, Hoardy-Web does fail to collect streaming media properly because Chromium has a bug that prevents collection of the first few KiB of all audio and video files, and its API design prevents collection of large files in general, but if we are talking about YouTube, then most of the data of those streaming media files Chromium will fetch while you watch a video there will, in fact, get collected even on Chromium.

So, in principle, to conform to those terms, Hoardy-Web would need to either disallow archival of all embedded media (which would defeat the point of it existing), or come bundled with a blacklist of URLs Google would claim you would be "unauthorized" to save to disk, and forcefully disallow archival for those. Even if such a blacklist could be made somehow (How do you expect somebody make such a thing, Google-san?), it would be very annoying and time-consuming to maintain.

(Meanwhile, on Firefox, Hoardy-Web will just silently collect everything you browser fetches. And addons.mozilla.org's policies do not restrict this.)

(Also, Chrome Web Store actually requires developers to pay Google to host their add-ons there while Mozilla's service is free. Meaning, you should go and donate to any free add-ons that do not violate your privacy and sell your data you installed from there. Their authors paid Google so that you could conveniently install their add-ons with a single click. Who else will pay the authors? Also, consider donating to Mozilla, things would be much, much worse without them.)
Alternatively, build it from source.

... check it actually works

Now load any web page in your browser. The extension will report if everything works okay, or tell you where the problem is if something is broken.

... and you are done

Assuming the extension reported success: Congratulations! You are now collecting and archiving all your web browsing traffic originating from that browser. Repeat extension installation for all browsers/browser profiles as needed.

Technically speaking, if you just want to collect everything and don't have time to figure out how to use the rest of this suite of tools right this moment, you can stop here and figure out how to use the rest of this suite later.

It took me about 6 months before I had to refer back to previously archived data for the first time when I started using mitmproxy to sporadically collect my HTTP traffic in 2017. So, I recommend you start collecting immediately and be lazy about the rest.

(Also, I learned a lot about nefarious things some of the websites I visit do in background by inspecting the logs Hoardy-Web produces. You'd be surprised how many big websites generate HTTP requests with evil tracking data at the moment you close the containing tab. They do this because such requests can't be captured and inspected with browser's own Network Monitor, so most people are completely unaware.)

... except, you should probably switch to `Submit dumps via 'HTTP'` mode

In practice, though, your will probably want to install at least the hoardy-web-sas simple archiving server (see below for instructions) and switch Hoardy-Web to Submit dumps via 'HTTP' mode pretty soon because it is very easy to accidentally loose data using other archival methods and, assuming you have Python installed on your computer, it is also the most convenient archival method there is.

Or, you can install the hoardy-web tool and run hoardy-web serve archiving server instead, then, again, switch Hoardy-Web to Submit dumps via 'HTTP' mode, and then enjoy safe persistent archival with replay and search, like on the screenshots above.

... or if you are unable or unwilling to do that

Alternatively, you can use the combination of archiving by saving of data to browser's local storage (the default) followed by semi-manual export into WRR bundles.

Or, alternatively, you can switch to Export dumps via 'saveAs' mode by default and simply accept the resulting slightly more annoying UI (on Firefox, it can be fixed with a small about:config change) and the facts that you can now lose some data if your disk ever gets out of space or if you accidentally mis-click a button in your browser's Downloads UI.

Recommended next steps

Next, you should read extension's Help page. It has lots of useful details about how it works and quirks of different browsers. If you open it by clicking the Help button in the extension's UI, then hovering over or clicking on links in there will highlight relevant settings.

See "Setup recommendations" section for best practices for configuring your system and browsers to be used with Hoardy-Web.

Installing the Pythonic parts

Pre-installation

Install Python 3:
- On Windows: Download Python from the official website.
- On a conventional POSIX system like most GNU/Linux distros and MacOS X: Install python3 via your package manager. Realistically, it probably is installed already.

Installation

Install the Pythonic parts:
- Install the hoardy-web-sas simple archiving server by following its "Installation" instructions.
- Install the hoardy-web tool by following its "Installation" instructions.
Test the results actually work:
- On Windows with unconfigured PATH environment variable:
```
python3 -m hoardy_web_sas --help
python3 -m hoardy_web --help
```
- On configured Windows and POSIX systems:
```
hoardy-web-sas --help
hoardy-web --help
```

Alternatively, on a system with Nix package manager

Install everything by running
```
nix-env -i -f ./default.nix
```
Test the results work:
```
hoardy-web-sas --help
hoardy-web --help
```
Also, instead of installing the add-on from addons.mozilla.org or from Releases on GitHub you can take freshly built XPI and Chromium ZIPs from
```
ls ~/.nix-profile/Hoardy-Web*
```
instead. See the extension's README for more info on how to install them manually.

Setup recommendations

In general

You can add hoardy_web_sas.py to Autorun or start it from your ~/.xsession, systemd --user, etc.
You can also make a new browser profile specifically for archived browsing, run Firefox as firefox -ProfileManager to get to the appropriate UI. On Windows you can just edit your desktop or toolbar shortcut to target
```
"C:\Program Files\Mozilla Firefox\firefox.exe" -ProfileManager
```
or similar by default to switch between profiles on browser startup.
In case you plan to ever share some of your captures, it is highly recommended you make separate browser profiles for anonymous and logged-in browsing with separate extension instances either
- pointing to separate archiving server instances dumping data to different directories on disk;
- or, alternatively, using the same archiving server, but using different default Bucket values in the Hoardy-Web extension.
Set the "anonymous" browser profile to always run in Private Browsing mode to prevent login persistence there. If you do accidentally login in "anonymous" profile, move those dumps out of the "anonymous" directory immediately.

This way you can easily share dumps from the "anonymous" instance without worrying about leaking your private data or login credentials.

Using `Hoardy-Web` with Tor Browser

When using Hoardy-Web with Tor Browser, you probably want to configure it all in such a way so that all of the machinery of Hoardy-Web is completely invisible to web pages running under your Tor Browser, to prevent fingerprinting.

Mostly convenient, paranoid

So, in the mostly convenient yet sufficiently paranoid setup, you would only ever use Hoardy-Web extension configured to archive captured data to browser's local storage (which is the default) and then export your dumps manually at the end of a browsing session, see re-archival intructions.

Yes, this is slightly annoying, but this is the only absolutely safe way to export data out of Hoardy-Web without using submission via HTTP, and you don't need to do this at the end of each and every browsing session.

Simpler, but slightly unsafe

You can also simply switch to using Export dumps via 'saveAs' by default instead.

I expect this to work fine for 99.99% of the users 99.99% of the time, but, technically speaking, this is unsafe. Also, by default, browser's UI will be slightly annoying, since Hoardy-Web will be generating new "Downloads" all the time, but that issue can be fixed with a small about:config change.

Most convenient, less paranoid

In theory, running ./hoardy_web_sas.py listening on a loopback IP address should prevent any web pages from accessing it, since the browsers disallow such cross-origin requests, thus making the normal Submit dumps via 'HTTP' mode setup quite viable. However, Tor Browser is configured to proxy everything via the TOR network by default, so you need to configure it to exclude the requests to ./hoardy_web_sas.py from being proxied.

A slightly more paranoid than normal way to do this is:

Run the server as ./hoardy_web_sas.py --host 127.0.99.1 or similar.
Go to about:config in your Tor Browser and add 127.0.99.1 to network.proxy.no_proxies_on.
Set the Server URL setting in the extension to http://127.0.99.1:3210/pwebarc/dump.

Why? When using Tor Browser, you probably don't want to use 127.0.0.1 and 127.0.1.1 as those are normal loopback IP addresses used by most things, and you probably don't want to allow any JavaScript code running in Tor Browser to (potentially, if there are any bugs) access to those. Yes, if there are any bugs in the cross-domain check code, with this setup JavaScript could discover you are using Hoardy-Web (and then, in the worst case, DOS your system by flooding your disk with garbage dumps), but it won't be able to touch the rest of your stuff listening on your other loopback addresses.

So, while this setup is not super-secure if your Tor Browser allows web pages to run arbitrary JavaScript (in which case, let's be honest, no setup is secure), with JavaScript always disabled, to me, it looks like a completely reasonable thing to do.

Best of both

In theory, you can have the benefits of both invisibility of archival to local storage and convenience, guarantees, and error reporting of archival to an archiving server at the same time:

Run the server as ./hoardy_web_sas.py --host 127.0.99.1 or similar.
But archive to browser's local storage while browsing.
Then, at the end of the session, after you closed all the tabs, set network.proxy.no_proxies_on, enable submission via HTTP while disabling saving to local storage, re-archive, your local storage should now be empty, unset network.proxy.no_proxies_on again.

In practice, doing this manually all the time is prone to errors. Automating this away is on the TODO list.

Then, you can improve on this setup even more by running both the Tor Browser and ./hoardy_web_sas.py in separate containers/VMs.

Alternatives

Sorted by similarity to Hoardy-Web, most similar projects first. "Cons" and "Pros" are in comparison to the main workflow of Hoardy-Web.

DownloadNet

A self-hosted web crawler and web replay system written in Node.js.

Of all the tools known to me, DownloadNet is most similar to the intended workflow of the Hoardy-Web. Similarly to the combination of Hoardy-Web extension and hoardy-web serve and unlike pywb, heritrix, and other similar tools discussed below, DownloadNet captures web data directly from browser's runtime. The difference is that Hoardy-Web does this using webRequest WebExtensions API and Chromium's debugger API while DownloadNet is actually a web crawler that crawls the web by spawning a Chromium browser instance and attaching to it via its debug protocol (which are not the same thing). This is a bit weird, but it does work, and it allows you to use DownloadNet to archive everything passively as you browse, similarly to Hoardy-Web, since you can just browse in that debugged Chromium window and it will archive the data it fetches.

Pros:

it's very similar to what Hoardy-Web aims to do, except

Cons:

it's Chromium-only;
it uses a custom archive format but gives no tools to inspect or manage those archives;
you are expected to do everything from the web UI.

Same issues:

When running under Chromium, a bunch of Chromium's bugs make many things pretty annoying and somewhat flaky.

Those issues have no workarounds known to me except for "switch to Firefox-based browser", which you can do with Hoardy-Web.

mitmproxy

A Man-in-the-middle SSL proxy.

Hoardy-Web was heavily inspired by mitmproxy and, essentially, aims to be to an in-browser alternative to it. I.e., unlike other alternatives discussed here, both Hoardy-Web and mitmproxy capture mostly-raw HTTP traffic, not just web pages. Unlike mitmproxy, however, Hoardy-Web is designed primarily for web archival purposes, not traffic inspection and protocol reverse-engineering, even though you can do some of that with Hoardy-Web too.

Pros:

after you set it up, it will capture absolutely everything completely automatically;
including WebSockets data, which Hoardy-Web add-on currently does not capture.

Cons:

it is rather painful to setup, requiring you to install a custom SSL root certificate; and
websites using certificate pinning will stop working; and
some websites detect when you use it and fingerprint you for it or force you to solve CAPTCHAs; and
mitmproxy dump files are flat streams of HTTP requests and responses that use custom frequently changing between versions data format, so you'll have to re-parse them repeatedly using mitmproxy's own parsers to get to the requests you want;
and then you'll still need some more tools to use those archives for Wayback Machine-like replay and generation of website mirrors.

Though, the latter issue can be solved via this project's hoardy-web tool as it can take mitmproxy dumps as inputs.

But you could just enable request logging in your browser's Network Monitor and manually save your data as `HAR` archives from time to time

Cons:

to do what Hoardy-Web does, you will have to manually enable it for each browser tab;
opening a link in a new tab will fail to archive the first page as you will not have Network Monitor open there yet; and then
you will have to check all your tabs for new data all the time and do ~5 clicks per tab to save it; and then
HARs are JSON, meaning all that binary data gets encoded indirectly, thus making resulting HAR archives very inefficient for long-term storage, as they take a lot of disk space, even when compressed;
and then you'll still need something like this suite to inspect the generated archives;
and then you'll still need some more tools to use those archives for Wayback Machine-like replay and generation of website mirrors.

Though, the latter issue can be solved via this project's hoardy-web tool as it can take HAR dumps as inputs.

But you could setup SSL keys dumping then use `Wireshark`, or `tcpdump`, or some such, to capture your web traffic

Pros:

after you set it up, it will capture absolutely everything completely automatically;
it captures WebSockets data, which Hoardy-Web add-on currently does not.

Cons:

it is really painful to setup; and then
you are very likely to screw it up, loose/mismatch encryption keys, and make your captured data unusable; and even if you don't,
it takes a lot of effort to recover HTTP data from the PCAP dumps; and
PCAP dumps are IP packet-level, thus also inefficient for this use case; and
PCAP dumps of SSL traffic can not be compressed much, thus storing the raw captures will take a lot of disk space.
and then you'll still need something like this suite to inspect the generated archives;
and then you'll still need some more tools to use those archives for Wayback Machine-like replay and generation of website mirrors.

And hoardy-web tool can't help you with the latter, at the moment.

archiveweb.page and replayweb.page

Browser extensions similar to the Hoardy-Web extension in their implementation, though not in their philosophy and intended use.

Overall, Hoardy-Web and archiveweb.page extensions have a similar vibe, but the main difference is that archiveweb.page and related tools are designed for capturing web pages with the explicit aim to share the resulting archives with the public, while Hoardy-Web is designed for private capture of personally visited pages first.

In practical terms, archiveweb.page has a "Record" button, which you need to press to start recording a browsing session in a separate tab into a separate WARC file. In contrast, Hoardy-Web, by default, in background, captures and archives all successful HTTP requests and their responses from all your open browser tabs.

Pros:

they produce and consume archives in WARC format, which is a de-facto standard;
their replay is more mature than what Hoardy-Web currently has.

Cons:

they produce and consume archives in WARC format, which is rather limited in what it can capture (compared to WRR, HAR, PCAP, and mitmproxy);
they are Chromium-only;
to make archiveweb.page archive all of your web browsing like Hoardy-Web does:
- you will have to manually enable archiveweb.page for each browser tab; and then
- opening a link in a new tab will fail to archive the first page, as the archival is per-tab;
it has no equivalent to problematic reqres status of Hoardy-Web, which is super useful for ensuring your captures are actually good, and not broken in some non-obvious ways because of networking or intermittent server errors;
archiveweb.page also requires constant manual effort to export the data out.

Differences in design:

archiveweb.page captures whole browsing sessions, while Hoardy-Web captures separate HTTP requests and responses;
archiveweb.page implements "Autopilot", which Hoardy-Web will never get (if you want that, Hoardy-Web expects you to use UserScripts instead).

Same issues:

Both Hoardy-Web and archiveweb.page store captured data internally in the browser's local storage/IndexedDB by default.

This is both convenient for on-boarding new users and helps in preserving the captured data when your computer looses power unexpectedly, your browser crashes, you quit from it before everything gets archived, or the extension crashes or gets reloaded unexpectedly.

On the other hand, this is both inefficient and dangerous for long-term preservation of said data, since it is very easy to accidentally loose data archived to browser's local storage (e.g., by uninstalling the extension).

Which is why Hoardy-Web has Submit dumps via 'HTTP' mode which will automatically submit your dumps to an archiving server instead.
When running under Chromium, a bunch of Chromium's bugs make many things pretty annoying and flaky, which --- if you know what to look for --- you can notice straight in the advertisement animation on their "Usage" page.

Those issues have no workarounds known to me except for "switch to Firefox-based browser", which you can do with Hoardy-Web.

SingleFile and WebScrapBook

Browser add-ons that capture whole web pages by taking their DOM snapshots and saving all requisite resources the captured page references.

Capturing a page with SingleFile generates a single (usually, quite large) HTML file with all the resources embedded into it. WebScrapBook saves its captures to browser's local storage or to a remote server instead.

Pros:

very simple to use;
they implement annotations, which Hoardy-Web currently does not.

Cons:

to make them archive all of your web browsing like Hoardy-Web does, you will have to manually capture each page you want to save;
they only captures web pages, you won't be able to save POST request data or JSONs fetched by web apps;
since they do not track and save HTTP requests and responses, capturing a page will make the browser re-download non-cached page resources a second time;
the resulting archives take a lot of disk space, since they duplicate requisite resources (images, media, CSS, fonts, etc) for each web page to make each saved page self-contained.

Differences in design:

they capture DOM snapshots, while Hoardy-Web captures HTTP requests and responses (though, it can capture DOM snapshots too).

WorldBrain Memex

A browser extension that implements an alternative mechanism to browser bookmarks. Saving a web page into Memex saves a DOM snapshot of the tab in question into an in-browser database. Memex then implements full-text search engine for saved snapshots and PDFs.

Pros:

pretty, both in UI and in documentation;
it implements annotations, which Hoardy-Web currently does not;
it has a builtin full-text search engine with indexing; meanwhile, at the moment, Hoardy-Web only has the non-indexed hoardy-web * --*grep* options; though, you can use recoll with hoardy-web as an input filter;
lots of other features.

Cons:

to make it archive all of your web browsing like Hoardy-Web does, you will have to manually save each page you visit;
it only captures web pages and PDFs, you won't be able to save POST request data or JSONs fetched by web apps;
compared to Hoardy-Web, it is very fat --- it's .xpi is more than 40 times larger;
it takes about 7 times more RAM to do comparable things (measured via about:performance);
it is slow enough to be hard to use on an older or a very busy system;
it injects content scripts to every page you visit, making your whole browsing experience much less snappy;
it performs a lot of HTTP requests to third-party services in background (Hoardy-Web does none of that);
you are expected to do everything from the web UI;
the resulting archives take a lot of disk space.

Differences in design:

it captures DOM snapshots and PDFs, while Hoardy-Web captures HTTP requests and responses (though, it can capture DOM snapshots too);
it has a builtin synchronization between instances, while Hoardy-Web expects you to use normal file backup tools for that.

pywb

A web archive replay system with a builtin web crawler and HTTP proxy. Brought to you by the people behind the Wayback Machine and then adopted by the people behind archiveweb.page.

A tool similar to hoardy-web serve.

Pros:

it produces and consumes archives in WARC format, which is a de-facto standard;
its replay capabilities are more mature than what hoardy-web serve currently has;
it can update its configuration without a restart and re-index of given inputs.

Cons:

it produces and consumes archives in WARC format, which is rather limited in what it can capture (compared to WRR, HAR, PCAP, and mitmproxy);
it has no equivalents to most other sub-commands of hoardy-web tool;
compared to hoardy-web serve, it's much more complex, it has a builtin web crawler (aka "pywb Recorder", which does not work for uncooperative websites anyway), and can also do capture by trying to be an HTTP proxy (which also does not work for many websites);

I assume it has all these features because archiveweb.page is Chromium-only, which forces it to be rather unreliable (see a list of relevant Chromium's bugs) and annoying to use when you want to be sure the whole page was captured properly (since it has no equivalent to problematic reqres status of Hoardy-Web).

Meanwhile, Hoardy-Web has problematic reqres tracking and the extension works perfectly well under Firefox-based browsers, which allow for much more reliable captures.
since hoardy-web serve uses a much simpler and faster to parse WRR file format, it is able to add new dumps to its index synchronously with their archival, allowing for their immediate replay.

heritrix

The crawler behind the Wayback Machine. It's a self-hosted web app into which you can feed the URLs for them to be archived, so to make it archive all of your web browsing:

A tool similar to hoardy-web serve.

Pros:

it produces and consumes archives in WARC format, which is a de-facto standard;
stable, well-tested, and well-supported.

Cons:

it produces and consumes archives in WARC format, which is rather limited in what it can capture (compared to WRR, HAR, PCAP, and mitmproxy);
it has no equivalents to most other sub-commands of hoardy-web tool;
you have to run it, and it's a rather heavy Java app;
to make it archive all of your web browsing like Hoardy-Web does, you'll need to write a separate browser plugin to redirect all links you click to your local instance's /save/ REST API URLs (which is not hard, but I'm unaware if any such add-on exists);
and you won't be able to archive your HTTP POST requests with it;
as with other similar tools, an HTTP server of a web page that is being archived can tell it is being crawled.

ArchiveBox

A web crawler and self-hosted web app into which you can feed the URLs for them to be archived.

Pros:

it produces and consumes archives in WARC format, which is a de-facto standard;
it has a very nice web UI;
it it's an all-in-one archiving solution, also archiving YouTube videos with yt-dlp, git repos, etc;
stable, well-tested, and well-supported.

Cons:

it produces and consumes archives in WARC format, which is rather limited in what it can capture (compared to WRR, HAR, PCAP, and mitmproxy);
to make it archive all of your web browsing like Hoardy-Web does,
- it requires you to setup mitmproxy with archivebox-proxy plugin;
- alternatively, you can run archivefox add-on and explicitly archive pages one-by-one via a button there;
in both cases, to archive a URL, ArchiveBox will have to download it by itself in parallel with your browser, thus making you download everything twice, which is hacky and inefficient; and
websites can easily see, fingerprint, and then ban you for doing that;
and you won't be able to archive your HTTP POST requests with it.

Still, probably the best of the self-hosted web-app-server kind of tools for this ATM.

reminiscence

A system similar to ArchiveBox, but has a bulit-in tagging system and archives pages as raw HTML + whole-page PNG rendering/screenshot --- which is a bit weird, but it has the advantage of not needing any replay machinery at all for re-viewing simple web pages, you only need a plain simple image viewer, though it will take a lot of disk space to store those huge whole-page "screenshot" images.

Pros and Cons are almost identical to those of ArchiveBox above, except it has less third-party tools around it so less stuff can be automated easily.

`wget -mpk` and `curl`

Pros:

both are probably already installed on your POSIX-compliant OS,
wget can produce archives in WARC format, which is a de-facto standard.

Cons:

to do what Hoardy-Web does, you will have to manually capture each page you want to save;
many websites will refuse to be archived with wget and making wget play pretend at being a normal web browser is basically impossible;
similarly with curl, curl also doesn't have the equivalent to wget's -mpk options;
can't archive dynamic websites;
changing archival options will force you to re-download a lot.

wpull

wget -mpk done right.

Pros:

it can pause and resume fetching;
it can archive many dynamic websites via PhantomJS;
it produces archives in WARC format, which is a de-facto standard and has a lot of tooling around it;
stable, well-tested, and well-supported.

Cons:

to do what Hoardy-Web does, you will have to manually capture each page you want to save;
you won't be able to archive your HTTP POST requests with it;
does not have replay capabilities, just generates WARC files.

grab-site

A simple web crawler built on top of wpull, presented to you by the ArchiveTeam, a group associated with the Wayback Machine which appears to be the source of archives for the most of the interesting pages I find there.

Pros:

it produces archives in WARC format, which is a de-facto standard and has a lot of tooling around it;
stable, well-tested, and well-supported.

Cons:

to do what Hoardy-Web does, you will have to manually capture each page you want to save;
it can't really archive dynamic websites;
you won't be able to archive your HTTP POST requests with it;
it does not have replay capabilities, just generates WARC files.

monolith and obelisk

Stand-alone tools doing the same thing SingleFile add-on does: generate single-file HTMLs with bundled resources viewable directly in the browser.

Pros:

simple to use.

Cons:

to make them archive all of your web browsing like Hoardy-Web does, you will have to manually capture each page you want to save;
they can't really archive dynamic websites;
you won't be able to archive your HTTP POST requests using them;
changing archival options will force you to re-download everything again.

single-file-cli

Stand-alone tool based on SingleFile, using a headless browser to capture pages.

A more robust solution to do what monolith and obelisk do, if you don't mind Node.js and the need to run a headless browser.

Archivy

A self-hosted wiki that archives pages you link to in background.

Others

ArchiveBox wiki has a long list or related things.

If you like this, you might also like

Perkeep

It's an awesome personal private archival system adhering to the same philosophy as Hoardy-Web, but it's basically an abstraction replacing your file system with a content-addressed store that can be rendered into different "views", including a POSIXy file system.

It can do very little in helping you actually archive a web page, but you can start dumping new Hoardy-Web .wrr files with compression disabled, decompress you existing .wrr files, and then feed them all into Perkeep to be stored and automatically replicated to your backup copies forever. (Perkeep already has a better compression than what Hoardy-Web currently does and provides a FUSE FS interface for transparent operation, so compressing things twice would be rather counterproductive.)
