chess-analysis.org vs Chess.com vs Lichess: Where Should You Analyze Your Games?

Updated

Use chess-analysis.org if you want a fast, no-sign-up Stockfish pass on a game you already played elsewhere and don't care about keeping a history. Use Chess.com or Lichess if you want analysis tied to your account, your game archive, and the rest of your training tools. The three aren't really competitors on features — they differ mainly in whether analysis is a standalone utility or part of a platform.

What each option actually is

chess-analysis.org is a single-purpose tool: you bring a game, it runs Stockfish, it shows you mistakes and better moves. Its own description says you can paste a PGN or import from Chess.com or Lichess, and that no sign-up is required. It doesn't host games or track your rating — it analyzes what you hand it.

Chess.com and Lichess are full platforms. You play there, your games are stored there, and each has a built-in analysis feature that runs on the same game you just finished. Analysis is one button inside a larger ecosystem (puzzles, lessons, opening explorer, tournaments).

Side-by-side

Dimension chess-analysis.org Chess.com Lichess
Account needed No sign-up required (per site description) Yes, to play and store games Yes, to play and store games
Where games come from Paste PGN, or import from Chess.com / Lichess Games played on Chess.com Games played on Lichess
Engine Stockfish Platform engine Stockfish
Cost Site lists a subscribe page and a "Buy Credits" link, so some features or volume may be paid — the free tier's exact limits aren't stated Free tier plus paid tiers Free
Extra tools Analysis only Lessons, puzzles, opening prep, social Puzzles, studies, opening explorer, teams
History/archive Not described as storing your games Yes Yes

The cost row is the one to be careful with. chess-analysis.org's page shows both a subscribe link and a "Buy Credits" entry, which means paid usage exists in some form — but the page doesn't state what's free, what costs credits, or what a subscription unlocks. Don't assume unlimited free analysis; check the site's own pricing before relying on it for volume.

When chess-analysis.org is the better pick

  • You played on Chess.com or Lichess but want a second opinion from a plain Stockfish run without opening the platform's full review flow.
  • You have a PGN from a tournament, a book, or a friend and just want it checked quickly.
  • You're on a device or browser where you don't want to log in, and you only need one game looked at.
  • You want to compare engines or depth settings outside a platform's fixed review.

The trade-off: nothing is saved for you, and you re-supply the game each time.

When Chess.com or Lichess wins

  • You want the analysis attached to the game in your archive so you can revisit it later.
  • You're already reviewing several games a day and want it to be one click, not a copy-paste.
  • You want the analysis to feed into other tools — opening stats, puzzle suggestions, progress tracking.
  • You want a guaranteed free path: Lichess analysis is free, and Chess.com has a free tier with paid upgrades.

A practical workflow

If you're unsure, this costs nothing and takes a minute:

  1. Finish a game on Chess.com or Lichess.
  2. Run the platform's built-in review first — it's already loaded and free to try.
  3. If you want a second pass, copy the PGN (both platforms let you export it) and paste it into chess-analysis.org.
  4. Compare where the two disagree. Engine disagreements usually mean a position is close, not that one tool is wrong.
  5. If you find yourself doing step 3 every game, that's your signal to just stay on the platform.

The short answer

For a one-off check on a game from anywhere, chess-analysis.org is the lower-friction choice — no account, paste and go. For ongoing review tied to your games and progress, Chess.com or Lichess is the better home, and Lichess is the safer bet if cost matters. Check chess-analysis.org's subscribe and credits pages before assuming heavy use is free.
