LibreChess · Chess, explained simply

Chess tools that run in your browser

LibreChess combines play, PGN review, puzzles, drills, repertoire practice, and a lesson library without requiring an account. Stockfish analysis runs locally with short searches, and the methodology explains the engine version, review thresholds, data sources, verification steps, and limitations.
