Chess.com vs Lichess: which to analyze your games on

Both platforms run Stockfish under the hood, so the raw engine quality is the same. The real differences are cost, how analysis is packaged, and the training features around it. The table below compares the parts that matter most when your goal is analyzing and improving from your own games.

Lichess provides free computer analysis, an opening explorer and study tools, all open and unlimited. Chess.com's Game Review is well designed and beginner-friendly, with plain-language explanations, but full access is a paid feature. For studying one game in depth, both are excellent - the main difference is cost and presentation.

Because both use Stockfish, the evaluations and best-move suggestions you get are effectively the same. What differs is the wrapper: Chess.com narrates the game with accessible commentary aimed at learners, while Lichess gives you a cleaner, unlimited engine readout and deep study tools that reward players who like to dig in themselves.

Lichess puzzles are free and unlimited, generated from real games, with modes like Puzzle Streak and Storm. Its lessons and practice drills are free, and its Studies feature lets you and others build shareable, annotated analysis - a genuinely strong free training toolkit.

Chess.com leans on a large, polished library of video lessons and structured courses, most of it behind a membership, plus tactics trainers like Puzzle Rush. If you want guided, produced instruction you are willing to pay for, Chess.com is deep; if you want unlimited free training material, Lichess covers most needs.

Cost is the clearest split. Lichess is entirely free and open-source, with no ads and no paywalled analysis, funded by donations. Chess.com is freemium: you can play and get limited analysis for free, but full Game Review, unlimited puzzles and the lesson library require a paid membership.

Chess.com has the larger user base, which usually means faster matchmaking and a bigger events and streaming scene. Lichess has a large, dedicated open-source community and a reputation for being ad-free and privacy-friendly. Both ship capable free mobile apps, so you can play and review on either platform from your phone.

Both platforms analyze one game at a time. Neither is built to tell you which openings cost you points across hundreds of games, which mistakes you repeat, or which winning positions you blow. That cross-game view is a different job, and it is where a dedicated tool helps regardless of where you play.

Audit Chess works with both Chess.com and Lichess: enter your username and it reviews your whole history, ranks your openings, profiles your endgames and style, and builds puzzles from your own blunders - free, no account.

Ratings are not directly comparable between the two platforms. Lichess ratings are typically 200-400 points higher than the equivalent skill level on Chess.com, because Lichess uses a different rating pool and more generous initial ratings. A 1500 on Chess.com is roughly a 1800-1900 on Lichess, depending on time control.

This matters for analysis because if you play on both platforms, your game histories reflect different rating environments. It does not affect which openings you should study, but it is worth understanding so you do not read too much into cross-platform rating comparisons.

If you play over-the-board (OTB) chess and want online play that mirrors tournament conditions, both platforms offer classical and rapid time controls. Lichess has a strong tradition of longer time controls and open tournaments. Chess.com has larger user numbers, which often means faster matchmaking at all levels.

For pure analysis quality, both platforms use Stockfish - the same engine. The difference is interface, integration, and cost. Your analysis results from either platform are equally useful as input for a whole-history tool.

Play where you enjoy the community and time controls; both have world-class analysis for individual games. Then add a whole-history tool to decide what to actually work on. Using a per-game tool and a whole-history tool together is the most efficient setup.
