ChessAnalyzer
Free Stockfish game review for Chess.com & Lichess
Skip daily paywalls. Get unlimited, free Stockfish game reviews for Chess.com & Lichess with move accuracy, key turning points, and blunder retries. Includes 3,000+ puzzles and sprints to train your mistakes. 100% free, no signup.
I built ChessAnalyzer out of a personal frustration that many chess players share: hitting paywalls just to learn from your games.
On most platforms, you get maybe one free game review a day before you're asked to pay $100+/year. But game analysis is how you actually improve. I wanted something fast, completely unrestricted, and 100% free for everyone.
What makes ChessAnalyzer different:
♟️ Runs Stockfish locally in your browser: Powered by Stockfish 19 via WebAssembly (WASM). Evaluations happen directly on your machine—no server queues, no subscription tiers, and your game data stays private.
🔄 Chess.com & Lichess in one place: Just type in any public username, pick a recent game, or paste a PGN / game review link.
🎯 "Retry Move" mode: Simply looking at an engine arrow doesn’t build muscle memory. When you blunder or make an inaccuracy, you can replay the move yourself before seeing the engine recommendation.
🏦 Personal Blunder Bank: Your missed wins, mistakes, and blunders are saved automatically so you can drill your own real game positions in custom puzzle sprints.
⚡ Puzzles & Timed Sprints: Over 3,000 tactical puzzles with theme filters, hints, plus 3-minute, 5-minute, and unlimited Puzzle Sprints.
🚫 Zero barriers: No accounts, no paywalls, no email collection, no daily limits.
I'd love your feedback!
Give it a spin with your latest game (or your favourite username) and let me know:
How does the analysis speed feel on your device?
What features or training modes would you like to see next?
Thanks for checking it out, and I'll be here all day hanging out in the comments to answer questions! ♟️🚀
