CodiMD lets you create real-time collaborative markdown notes on all platforms. Inspired by Hackpad, with more focus on speed and flexibility, and build from HackMD source code. Feel free to contribute.
Thanks for using! 😄

CodiMD was recently renamed from its former name was HackMD. CodiMD is the free software version of HackMD. It was the original Version of HackMD. The HackMD team initiated CodiMD and provided a solid code base. Due to the need of paying bills, A fork was created and called HackMD EE, which is a SaaS (Software as a Service) product available at hackmd.io.
We decided to change the name to break the confusion between HackMD and CodiMD, formally known as HackMD CE, as it never was an open core project.
Just to more confusion: We are still friends with HackMD ❤️
For the whole renaming story, see the related issue
Chrome >= 47, Chrome for Android >= 47
Safari >= 9, iOS Safari >= 8.4
Firefox >= 44
IE >= 9, Edge >= 12
Opera >= 34, Opera Mini not supported
- Android Browser >= 4.4
- Node.js 6.x or up (test up to 7.5.0) and <10.x
- Database (PostgreSQL, MySQL, MariaDB, SQLite, MSSQL) use charset
utf8 - npm (and its dependencies, especially uWebSockets, node-gyp)
- For building CodiMD we recommend to use a machine with at least 2GB RAM
- Download a release and unzip or clone into a directory
- Enter the directory and type
bin/setup, which will install npm dependencies and create configs. The setup script is written in Bash, you would need bash as a prerequisite. - Setup the configs, see more below
- Setup environment variables which will overwrite the configs
- Build front-end bundle by
npm run build(usenpm run devif you are in development) - Modify the file named
.sequelizerc, change the value of the variableurlwith your db connection string For example:postgres://username:password@localhost:5432/codimd - Run
node_modules/.bin/sequelize db:migrate, this step will migrate your db to the latest schema - Run the server as you like (node, forever, pm2)
You can quickly setup a sample Heroku CodiMD application by clicking the button below.
If you deploy it without the button, keep in mind to use the right buildpacks. For details check app.json.
To install use helm install stable/hackmd.
For all further details, please check out the offical CodiMD K8s helm chart.
Debian-based version:
Alpine-based version:
The easiest way to setup CodiMD using docker are using the following three commands:
git clone https://github.com/hackmdio/codimd-container.git
cd codimd-container
docker-compose upRead more about it in the container repository…
Install CodiMD on Cloudron:
If you are upgrading CodiMD from an older version, follow these steps:
- Fully stop your old server first (important)
git pullor do whatever that updates the filesnpm installto update dependencies- Build front-end bundle by
npm run build(usenpm run devif you are in development) - Modify the file named
.sequelizerc, change the value of the variableurlwith your db connection string For example:postgres://username:password@localhost:5432/codimd - Run
node_modules/.bin/sequelize db:migrate, this step will migrate your db to the latest schema - Start your whole new server!
- migrate-to-1.1.0
We deprecated the older lower case config style and moved on to camel case style. Please have a look at the current config.json.example and check the warnings on startup.
Notice: This is not a breaking change right now but in the future
We don't use LZString to compress socket.io data and DB data after version 0.5.0. Please run the migration tool if you're upgrading from the old version.
We've dropped MongoDB after version 0.4.0. So here is the migration tool for you to transfer the old DB data to the new DB. This tool is also used for official service.
