About Lichess
Lichess is a free and open-source online chess platform where players can compete in live games, solve puzzles, study openings, and analyze positions. It runs entirely in the browser without ads, trackers, or paywalls, and the full source code is available under the AGPL license.
The site supports every major chess variant, time control, and rating system, alongside tournaments, simultaneous exhibitions, and team battles. A built-in computer analysis powered by Stockfish reviews games and highlights mistakes, while the studies feature lets coaches and players build interactive lessons.
Lichess is run by a registered non-profit and funded by donations, which means every feature, including correspondence chess, opening explorer, and engine analysis, is available to all users at no cost.
