Blunder-less
Blunder-less is a free, browser-based chess analysis tool built for players who want to stop repeating the same opening mistakes. By connecting your Chess.com username, the platform downloads your recent games and runs them through Stockfish to identify recurring blunders, lost opportunities, and positional patterns that keep costing you points. The interface is intentionally minimal — just enter your username, hit analyze, and get a focused report on the mistakes you make most often in the opening phase. Unlike broad game-review tools that drown you in engine lines, Blunder-less narrows the scope to repeated errors so you can target your study time on the specific lines and ideas that actually hurt your results. It is powered by Stockfish and built by indie developer Pol Sust as a utility for the chess community.
