Help lichess.org

So you like chess, free software, and being useful? Great! We need your help making lichess better. Even if you can't code, don't worry, there are plenty of ways to contribute to the lichess project.

Translate to your native language

Lichess currently supports 90 different languages but there's plenty more to do. 93 more languages need to be started and many languages are near completion. If you speak a language that currently isn't (fully) supported by lichess, we'd love for you to help us out. Head over to the translation center to get started.

Provide a server for chess analysis

Lichess provides computer analysis for free to all users. The world-class open source Stockfish engine is used to analyse players games (example of an analysed game).

This is a CPU intensive operation, and requires many servers in order to provide fast and accurate analysis.

If you have a server with spare CPU power, you can help.

Lichess AI needs a lot of CPU power, some RAM, almost zero disk IO, and very little bandwidth.
Here's a typical server:

  • 4 or more threads faster than 2Ghz (anything above is better)
  • 512MB RAM
  • 100MB disk space
  • a little bandwidth for communicating with lichess' main server (one HTTP request every 5 seconds)
  • no inbound port is required. Your server calls lichess.org; not the other way around
  • you can stop your server at any time, without giving us a notice

You will need to install fishnet, our open-source AI client. Also you need to get a private API key from us.

For more details, please contact contact@lichess.org, or join #lichess IRC channel on freenode and ping ornicar.

Design

Lichess is constantly under development, new features and designs are implemented on a weekly (if not more frequent) basis, but we don't always get it right; that's where you can help us out. If you see something that could be improved, or done differently there's a few ways you can see your change implemented:

  • Design how you think the site should look in a graphical suite such as Photoshop. This will help the designers more directly approach and implement a solution. In most cases this is far more useful than a lengthy written document.
  • Know a thing or two about HTML and CSS? Even better! Head on over to our GitHub page and create a pull request with the change you would like to see implemented. It's as easy as editing the source-code in-browser (right click > inspect element), and then pasting the changes to the necessary files in the git directory.

We're also looking for skilled or enthusiast graphical designers to help with upcoming projects. Enquire on the freenode IRC channel #lichess to find out more.

Write code

So you can code, eh? That's great! Join the #lichess IRC channel on freenode and we'll find an interesting challenge for your skills.
