What Stockchess offers

One-step game import by Chess.com or Lichess username; PGN paste.
Stockfish 18 running in your browser — the analysis happens on your device.
Accuracy for both players, an estimated Elo for the game, evaluation graph, best-move arrows, opening name.
Move classes with open rules; the brilliant move rule has its own page.
A "why?" explanation for bad moves (fork, undefended piece, missed mate…).
A Weakness Report for your last 5–20 games and puzzles from your own mistakes.

Chess.com's strengths

Chess.com's review includes virtual coach explanations (Coach Explanations); per its support page they are unlimited with Diamond¹.
If you already have a paid membership, unlimited reviews are already yours.

Results are not identical. Stockchess is not a copy of Chess.com's Game Review. Engine settings, the accuracy formula and the class rules differ; in the same game the accuracy and badges can come out differently.

Another free option: Lichess

Lichess is free too: its analysis board is unlimited, and deep server analysis is 40 games per day on a free account (lichess.org/features, checked on October 21, 2026). If your games are on Lichess, it's a good option as well.

Which one should you use?

If you don't need more than one review a day, or you have a paid Chess.com membership, Chess.com's own review is enough. If you want to review every game for free, or look at several games together to see your weak spots, try Stockchess.
