About chess.rodeo - Free Chess Analysis
chess.rodeo provides deep analysis of your Chess.com and Lichess games using Stockfish engine.
Features:
• The verdict right on the game-over screen — accuracy, blunders and mistakes, before you click anything
• One-click import from Chess.com and Lichess
• Deep Stockfish analysis (depth 15+)
• Move-by-move classification (best, excellent, mistake, blunder)
• Accuracy scores using Lichess formula
• Opening detection with ECO codes
• Game phase analysis (opening, middlegame, endgame)
• Batch analysis across multiple games
• Identify patterns and weaknesses
How to use:
1. Play a game on Chess.com or Lichess
2. When it ends, the button already tells you how it went: "87% accurate · 1 blunder, 1 mistake"
3. Click "Analyze on chess.rodeo" for the full move-by-move analysis
4. Get personalized improvement recommendations
The verdict on the button is free and needs no account: chess.rodeo keeps a large store of positions that have already been analysed, and most games walk through many of them. While it covers only part of your game it says so — "87% accurate · 16 of 32 moves" — because a number without its coverage reads as final when it is not. A chess.rodeo Pro subscription has the engine fill in the rest, so the verdict covers the whole game.
Privacy: The extension reads the finished game's moves and your public Chess.com or Lichess username from the page, and sends them to chess.rodeo to get the verdict back. The username is used for one thing: if your chess.rodeo account asked for new games to be analysed in the background, this one is analysed straight away. If you press "Analyze on chess.rodeo" in the extension's menu, the game on the page you have open, or its address, is sent to chess.rodeo so it can open it. No analytics of its own, no tracking, nothing stored on your device. If you are signed in to chess.rodeo, your session token is sent with it so the server knows your subscription and the language you chose there; it goes to chess.rodeo and nowhere else.
