A Python bridge that connects chess engines (UCI, XBoard, or homemade) to the Lichess Bot API, letting you run a bot account that plays games on lichess.org. It supports all variants and time controls, matchmaking, tournaments, opening books, and endgame tablebases.

Use cases

  • connect a chess engine like stockfish to lichess
  • run a bot account on lichess.org
  • make my chess engine play online games
  • enter lichess bot tournaments with my engine
  • add matchmaking and opening books to a lichess bot
  • host a chess bot on windows linux or docker

When to choose

  • you have a UCI/XBoard chess engine or custom Python engine and want it to play on Lichess
  • you want matchmaking, tournament play, and PGN saving handled for you
  • you want a maintained, well-documented bridge with cross-platform and Docker support

When to avoid

  • you want a bot for sites other than lichess.org
  • you want to play with a normal (non-BOT) lichess account, since Lichess requires upgrading to a BOT account
  • you need a graphical chess interface rather than an automated bot
