Executive Summary

Lichess is a non-profit, open-source chess platform that provides a professional-grade experience entirely free of charge and without advertisements. It serves as a major market disruptor by offering features—such as unlimited puzzles and deep computer analysis—that competitors typically gate behind subscriptions. However, the platform is currently experiencing a period of user dissatisfaction following a major mobile app update that has introduced stability issues and UI regressions.
