StockFishy: Chess Move Analyzer

Chess analysis for Chess.com & Lichess: every legal move rated and color-coded by Stockfish, piece by piece, to help you learn.

StockFishy rates every move on the board — not just the best one. Most chess analysis tools show you a single "best move" and leave you to guess why everything else is worse. StockFishy is different: click any piece on Chess.com or Lichess and see every legal move it can make, each one rated and color-coded by the Stockfish chess engine — from Best down to Blunder — so you understand the position, not just the answer. FEATURES • Every move, every piece — click any piece to reveal all its legal moves, ranked and color-coded by quality (Best, Excellent, Good, Inaccuracy, Mistake, Blunder) • See what's coming next — a dashed arrow previews the reply Stockfish expects from your opponent after the top move • Continuous analysis — turn on auto-analyze and get fresh ratings after every move, yours and theirs, with zero clicking • Runs locally — Stockfish runs entirely in your browser on your own machine; no position or game data is ever sent to a server • Built for learning — designed to help you understand why a move is good or bad, not just hand you an engine line to copy HOW IT WORKS Open a game on Chess.com or Lichess.org. Click "Analyze Position" (or press Alt+A / Option+A) to see the top-rated moves board-wide. Click any piece to see every move it can legally make, each with its own rating. Toggle Continuous Analysis to get fresh ratings automatically after every move in the game. PRICING StockFishy is free to use, up to 50 analyzed positions per day. Paid plans (starting at $3/month) raise that daily limit for players who want deeper, more frequent analysis. See stockfishy.com/pricing for details. Works on Chess.com and Lichess.org.
