Why use Chessomy for Lichess analysis
Stockfish 17.1 – same engine as Lichess
Lichess uses Stockfish for its own analysis. Chessomy uses the same engine, running locally in your browser at depths up to 50—no server delay.
Your games never leave your device
Lichess games are fetched from the public API, then analyzed entirely on your device. No PGN is uploaded to Chessomy servers. Ever.
Offline after first load
Once your games are imported and analyzed, you can review them, study your blunders, and check statistics without internet.
Cross-platform statistics
If you play on both Lichess and Chess.com, Chessomy's statistics dashboard combines your game history from both platforms for a complete picture.
Common questions about Lichess analysis
How does Chessomy fetch my Lichess games?
Chessomy uses the Lichess public API (lichess.org/api) to fetch your recent games by username. No Lichess account login or OAuth is required—only your public username.
Is Chessomy affiliated with Lichess?
No. Chessomy is an independent tool that uses the Lichess public API. Lichess is open-source and its API is freely available. We're not affiliated with or endorsed by Lichess.
Why not just use Lichess's built-in analysis?
Lichess has excellent built-in analysis, and it's free. Chessomy adds value in different ways: it runs analysis offline, generates custom blunder puzzles from your mistakes, provides a cross-platform statistics dashboard, and includes a Nemesis bot that plays your own worst openings against you.
How accurate is Chessomy compared to Lichess analysis?
Both use Stockfish. Chessomy uses the WebAssembly single-threaded build, while Lichess runs multi-threaded Stockfish with NNUE on their servers. Lichess's server analysis may be slightly more precise at equivalent depths, but Chessomy's local analysis is faster to start and has no queue.
