Free Chess Game Analyzer & Stockfish Analysis Online

Chess Ramp is a free chess game analyzer powered by the Stockfish chess engine, running entirely in your browser. Paste or upload a PGN, or link your Chess.com or Lichess account, to get an instant move-by-move chess game review that highlights blunders, mistakes, inaccuracies, and brilliant moves — free chess analysis online, no account required.

Every move in your game is evaluated and classified the way a coach would annotate it: best moves and brilliancies on one end, inaccuracies, mistakes, and blunders on the other. Alongside the move list you get an evaluation graph of the whole game, an accuracy score for both players, and an estimated rating based on how you actually played — not just the result. In practice it doubles as a chess accuracy checker and blunder finder for any game you feed it.

The daily puzzle is free too, with a solve streak to keep you coming back. Beyond that, Chess Ramp Premium adds opening practice, rated puzzle training, a mistake trainer built from your games, Position Master, and practice games against engine bots.

Because Stockfish runs locally in your browser via WebAssembly, your games are never uploaded to a server: analysis is private, there is no queue, and there is no daily cap. Review one game or a hundred — the engine is yours for as long as the tab is open.
