Lichess online chess platform

Lichess is a free and open-source online chess server, founded by French programmer Thibault Duplessis in 2010. Unlike many commercial platforms, it is run by a registered non-profit organization focused on providing a high-quality chess experience without advertisements or paywalls.

The platform's infrastructure and development are decentralized and supported by a global community of volunteers and contributors. Its code is open for anyone to inspect or contribute to, reinforcing its mission as a public utility for the global chess community. Lichess is funded entirely by user donations, ensuring it remains independent from corporate interests.
