Lichess (/ˈlɛs/; LEE-ches) is a free and open-source Internet chess server run by a non-profit organization of the same name. Users of the site can play online chess anonymously and optionally register an account to play games to earn a rating on Lichess. Lichess is ad-free and all the features are available for free, as the site is funded by donations from patrons, who receive a special badge as thanks for their support. Features include chess puzzles, computer analysis, tournaments and chess variants.
