Hey Product Hunt! 👋
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?

Thanks for checking it out, and I'll be here all day hanging out in the comments to answer questions! ♟️🚀
