Deep server-side analysis
Stockfish runs on our servers — not in your browser. No lag, no battery drain, no fan noise.
depth ≥ 22 · cloud

Detailed move classification
Every move is labelled: brilliant, great, best, good, inaccuracy, mistake, miss, blunder. Eight registers instead of “+0.4 / −1.1”.
8 categories
[04]
Game Insights
Not “here are your 17 mistakes” but “here are the four patterns that keep repeating”. Blind spots, recurring blunders, systematic tempo loss.

Accuracy rating
Accuracy by the lichess formula, computed for both players. Comparable to any standard analysis, no secret scale of our own.
lichess-compatible

Opening detection
Automatically recognises the opening from a 3000+ ECO variation database. From move one you see which theory you hit — and where you left it.

Frequently asked
01
Is chess.rodeo really free?
Yes. Game analysis is free — import from Chess.com, Lichess or upload PGN files and get a Stockfish review with no daily limits. Pro unlocks advanced extras: auto-import, learning moments, opening mistakes and a repertoire explorer.
02
Which chess engine do you use?
Stockfish 18 — the strongest open-source chess engine in the world. Analysis runs on our servers at depth 15+, and many positions are pre-analysed at depth 20+ from the Lichess database for instant results.
03
How is accuracy calculated?
We use the same formula as Lichess. The centipawn loss of each move is converted into a win probability, then averaged across every move. The result is a percentage reflecting how close your moves are to the engine’s best lines.
04
Can I analyse games from any platform?
Directly from Chess.com and Lichess by username. For other platforms, export your games as PGN files and upload them here. We support multi-game PGN files.
05
How do Game Insights work?
Insights analyse the games you’ve already reviewed and find patterns in your play. The free tier uses your stored analyses; Pro can automatically fill in missing deep analysis and unlocks learning moments, opening mistakes and the repertoire explorer.
06
Is there a Chrome extension?
Yes. Install our extension to analyse games straight from Chess.com in one click. After a game ends you’ll see an "Analyze on chess.rodeo" button that imports and reviews the game automatically.
