Requirements

Important

Your terminal needs to support true color, and using different fonts in your terminal may cause display errors.

These are tested terminals on different operating systems:

System	Tested	Notes
Windows 11	✅	Works fine
Windows 10	✅	Works without true color
Linux (ubuntu)	✅	Works fine
Mac OS	❌	Should work fine

Getting started

Download latest release & unzip the file

Windows
Double click on KC-Checker.exe

Linux
Open terminal and enter

chmod +x KC-Checker

Now run it with

Or build it yourself

1. Install Prerequisites:

   • Go
   • Git

2. Clone the Project: Open your terminal and run: git clone https://github.com/Kuucheen/KC-Checker.git

3. (OPTIONAL) Set Up GeoLite2 Database: If you want to determine the country and type (ISP, Datacenter, or Residential) of the proxies, you'll need to download the GeoLite2 Country and GeoLite2 ASN Database from MaxMind.

   • After downloading, replace the existing databases in the helper directory.
   • Ensure they have the same names: GeoLite2-ASN.mmdb and GeoLite2-Country.mmdb.
     
     

   Note: These databases are not included in the repository due to their licensing restrictions. However, they are bundled in the prebuilt version.

Customize Settings

Note

For most users, the default settings will probably be sufficient.

Details for settings.json

1. threads:
   Maximum number of threads
   

2. retries:
   Number of retries for a request
   

3. timeout:
   Timeout duration for requests in ms
   

4. privacy_mode:
   If set to true, the proxies will be blured with "*" while checking

5. copyToClipboard:
   If set to true, all proxies checked will be copied to clipboard when saving them to a file

6. autoSelect:
   When setting one or more protocols are set to true, it will automatically start checking with the selected protocols.

7. autoSave:
   timeBetweenSafes: Seconds between the autoSave
   ip:port: If set to true it will automatically save the proxies with these format every timeBetweenSafes seconds
   protocol://ip:port: Same here
   ip:port;time: Same here
   custom: You can set a custom autoSave format here. If its not empty it will save it with this format. At the end of a checking process theres an option for "CUSTOM", where you can build your own output. You can put the output you built there in here.
   

8. timeBetweenRefresh:
   This is how often the screen updates in ms. If you experience high CPU usage, it is recommended to set it higher.

9. iplookup:
   A website that returns the ip. This is needed to know if the proxies are Transparent. The website will only be used once when starting the checker.

10. judges_threads:
    Maximum threads for selecting the judge

11. judges_timeout:
    Timeout duration of judges in ms

12. judges:
    url: This is the url the proxy will connect to while checking
    regex: The proxy will only be valid if the regex is found. When "default" is used it will check the headers. Headers are needed to determine the anonymity level of the proxies.
    If there are multiple judges the checker will use the fastest one

13. blacklisted:
    Websites that contain blacklisted ips. These ips won't be checked

14. bancheck:
    If a website URL is provided, the program verifies whether the proxy can successfully access the site. Proxies that have been checked against the website will be organized and stored in the banchecked directory.

15. keywords:
    The program inspects the content of the website (in the bancheck option) accessed through the proxy to determine if it contains the specified keywords or phrases. If the proxy successfully reaches the site and the desired keywords are found it will safe them in the banchecked directory. If the keywords are not found they will not be safed in the banchecked directory (even when the proxy was able to reach the site).

16. transport:
    These are the settings used for making a request. Only touch this option if you know what you are doing.

You can blacklist custom proxies by adding them in blacklisted.txt
