Get Involved

If you're interested in helping out with the Stockfish project, you've come to the right place.


Help improve Stockfish by volunteering some of your computer's processor cores to the project! Gary Linscott has built an innovative distributed testing framework called Fishtest. All you need to do is set up Fishtest, and whenever a change is committed to the project repository, your computer can join many others in testing that change by playing thousands of games against an older version to see if the change is an improvement.

GitHub Project

Want to help improve Stockfish? Fork the project on GitHub and commit away. Thanks to the aforementioned testing framework, you'll be able to verify your changes. Submit a pull request when you want your changes to be pulled back to the main branch.
