Lichess vs chess.rodeo for Game Analysis
Both are free. Both run Stockfish. Both are unlimited. Neither one paywalls analysis. So which should you actually use? The honest answer depends on whether you want to save what you find — or just see “what should I have played?” in two seconds.
TL;DR
- ✓ Both are free, both unlimited, both use full Stockfish. No paywall on either.
- ✓ Use chess.rodeo when: you want one-paste-to-engine, no account, ephemeral. The “analyze this Chess.com game right now” tool.
- ✓ Use Lichess when: you want to save the analysis, build a study, share a permanent URL, or use the opening explorer + tablebases.
- ✓ Real workflow: most players use both — Lichess for organized study, chess.rodeo for fast one-off analysis without logging in.
The Honest Framing
Most “X vs Y” posts on chess analysis tools are about free-vs-paywalled. Lichess vs chess.rodeo is different. Both are free. Both are unlimited. Both run the same engine. There is no gotcha and no upsell on either side.
The real difference is scope. Lichess is a full chess platform — play games, save studies, do puzzles, browse opening databases, query tablebases, follow tournaments — and analysis is one feature among many. chess.rodeo is a focused analysis tool — one URL, paste a PGN or FEN, see Stockfish output, done.
That difference points each tool at a different real-world job. Below is which job belongs to which.
Side-by-Side: Analysis Features

| Cost | Free (donation-funded) | Free |
| Account required | Optional (needed to save) | No |
| Engine | Stockfish (full + cloud) | Stockfish (full) |
| Unlimited games | Yes | Yes |

Neither tool ads, neither tool tracks, neither tool paywalls. The choice is about workflow, not pricing.
What Lichess Gives You
Lichess is the open-source full-platform alternative to Chess.com. For analysis specifically, you get a deep, well-integrated toolkit:
- ✓ Full Stockfish, two ways. Cloud evaluations for common positions (instant) plus an in-browser Stockfish NNUE you can run client-side. Both full-depth.
- ✓ Computer analysis. One-click whole-game review with eval bars, blunder / mistake / inaccuracy markers, and best-move alternatives — like Chess.com’s Game Review, but free and uncapped.
- ✓ Studies. Annotate any position or game with text, arrows, variations, and chapters. Studies live at a permanent URL you can share or bookmark.
- ✓ Opening explorer. Query either the Masters database (2200+ rated games since 1952) or the Lichess database (every game ever played on Lichess) for any position.
- ✓ Endgame tablebases. Syzygy 7-piece tablebases give perfect play for any position with 7 or fewer pieces — useful for endgame study.
- ✓ Account-saved game history. If you play on Lichess, every game auto-analyzes and lives in your profile — searchable, taggable, shareable.
The tradeoff: you get the most from Lichess analysis when you have a free account, and the UI is busier because the platform does so many things. For a focused “just analyze this PGN” session, that breadth is overhead.
What chess.rodeo Gives You
chess.rodeo — Paste a PGN, Get Stockfish, Done
chess.rodeo treats analysis as a one-shot tool, not a platform. Open the page, paste a PGN or set up a position, get full Stockfish output. No account, no email, no game history.
- ✓ No account, ever. No email, no password, no sign-in flow.
- ✓ Two-second start. Open the URL, paste, see eval. No platform to navigate.
- ✓ Full-strength Stockfish. Same engine as Lichess and Chess.com’s premium tier.
- ✓ Ephemeral by design. Nothing is saved server-side — privacy by default. Close the tab and the analysis is gone.
- ✓ PGN from anywhere. Chess.com games, Lichess games, OTB games you type in, FEN positions you set up — all work.
The tradeoff: chess.rodeo doesn’t save anything. No game history, no studies, no opening explorer, no puzzles. If you want the analysis to persist or to live alongside structured study, Lichess is the better home.
Which to Use When
Use chess.rodeo when…
- ✓ You want to analyze a Chess.com game right now without making an account.
- ✓ You want a one-off engine check on a single position or FEN.
- ✓ You don’t want your games saved to a profile anywhere.
- ✓ You’re on a shared, locked-down, or guest-mode browser where signing into Lichess is friction.
- ✓ You want the fastest possible “paste-to-eval” loop — no UI to learn.
Use Lichess when…
- ✓ You want to save the analysis, annotate it, and come back to it later.
- ✓ You want to share an annotated game with a permanent URL.
- ✓ You’re building a long-term opening repertoire with chapters and variations.
- ✓ You want the opening explorer or endgame tablebases alongside the engine.
- ✓ You already have a Lichess account and the analysis belongs in your normal workflow.
- ✓ You want puzzles, blitz games, or a full platform experience in the same tab.
The Combined Workflow (Most Players Use Both)
These tools aren’t actually competing. They serve different moments in the same study loop. Here is how a typical improving player can combine them:
- Play your blitz games on Chess.com or Lichess — whichever has your friends and rating.
- Quick post-mortem on chess.rodeo — right after a loss, paste the PGN, see exactly where you went wrong. 30-second loop with no context-switching to a login flow.
- Move the interesting ones into a Lichess study — when a game has a lesson worth keeping, paste the PGN into a Lichess study, annotate the critical moment, tag the theme (e.g. “back-rank,” “rook endgame”).
- Browse your tagged studies weekly — your Lichess studies become a personal mistake database. Review them before your next session.
chess.rodeo is the “low-friction triage” tool; Lichess is the “long-term memory.” You don’t need to pick one.
How to Move a Game Between Lichess and chess.rodeo
Both tools speak PGN. PGN is the universal chess-game text format — any chess site can export and import it.
Lichess → chess.rodeo
- Open the Lichess game or study chapter.
- Click the FEN/PGN tab below the board and copy the PGN.
- Paste into chess.rodeo’s import field.
- Full Stockfish output appears immediately.
chess.rodeo → Lichess study
- Copy the PGN out of chess.rodeo (analysis is preserved).
- On Lichess, go to Studies → New study → New chapter → PGN.
- Paste, name the chapter, save.
- Now the analyzed game lives at a permanent Lichess URL.
You can also pipe games through the chess.lc PGN viewer as a quick offline preview before sending the PGN to either engine.
Common Misconceptions
“Lichess analysis is stronger because it uses cloud evals.”
Cloud evals are faster for positions already in Lichess’s cache, but the engine running the analysis is the same Stockfish either way. For a position not in the cache, on-demand evaluation on chess.rodeo finishes in comparable time at the same depth.
“chess.rodeo must be ad-supported because it’s free with no account.”
No ads. No tracking. The site is designed to be a focused utility, the same way Lichess is donation-funded rather than ad-funded.
“If I use chess.rodeo I lose my Lichess studies.”
Nothing changes about your Lichess account. The tools share PGN as a common format — using chess.rodeo for triage and Lichess for permanent storage is a normal pattern.
“I should just pick one and stick with it.”
Two free tools with different shapes solve different problems better than one tool solves both. Most strong amateurs run a Lichess account for play and structured study and use a no-account engine like chess.rodeo for fast one-off evaluations.
