The Chess Programming Wiki is back! One of the most valuable resources for chess programming is now hosted by Lichess. While edits and logins are currently disabled, we’re working on restoring such features soon. Stay tuned!

Our 2026 Lichess Meetup will take place in Prague, Czech Republic, on September 20! Join us for an open OTB blitz event, snacks, and camaraderie. Boards and sets will be provided. More details coming soon!

Team messages now appear on the new Team Updates page, instead of going in your inbox!

You can now customize the shape of buttons and other elements on Lichess! Open your account menu, go to Theme settings, and adjust the Roundness to make corners rounded or square.

Our Game of the Month July Contest is underway: Share your best Lichess standard game played in July 2026 until 2026-08-12! The winner will be announced on 2026-08-24, followed by a blog post with commentary on the game.
