Free Chess Game Review — Unlimited, No Account
Chessda is a free, unlimited chess game review you can use without an account — an open alternative to Chess.com’s Game Review.
Most polished game reviews are metered — you get a taste, then hit a paywall or a daily limit. Chessda removes the meter: unlimited reviews, no account, no ads, because Stockfish runs in your browser, so there’s nothing to ration. Review a game now →

Frequently asked questions
Is there a truly free, unlimited chess game review?
Yes. Chessda gives you unlimited Stockfish-powered game reviews with no account, no ads, and no daily cap, because the engine runs in your own browser — there’s nothing to meter.
How is this different from Chess.com’s Game Review?
The features are the same idea — move classifications, accuracy, estimated rating, an eval graph, and a guided walkthrough — but here they’re free and unlimited with no account. Chess.com offers Game Review with limits on its free plan and the full experience to members.
Do I need a Chess.com or Lichess account?
No account anywhere is required to use Chessda. You can still import your games by typing a Chess.com or Lichess username — that fetches public games directly in your browser.
Is it really private?
Yes. Analysis runs locally in your browser; your games are never uploaded to a server.
