Description

Lichess is a free, open-source chess platform designed to provide a clean, accessible, and community-driven experience for chess fans. Unlike chess.com, Lichess operates as a non-profit, relying entirely on voluntary donations to sustain its development and infrastructure. The platform’s codebase is fully open-source, allowing users to audit, contribute to, or even self-host their own instances. This approach aligns with principles of digital sovereignty and user empowerment, as it removes reliance on proprietary systems and closed ecosystems.

The platform does not track users, collect personal data, or employ third-party analytics, ensuring a highly privacy-friendly environment. There are no advertisements, no data mining, and no mandatory registrations, with all features available without creating an account. Games, puzzles, and progress are saved both locally and on servers, enabling seamless offline play and continuity across devices.
