About ReplayChess
ReplayChess is a free, open-source chess platform where chess history is something you play rather than watch.
Every chess fan knows the moment: the video pauses at the critical position, you find the winning move, and then the narrator plays it for you. ReplayChess is the other half of that experience. Pick one of 50+ legends, from Morphy and Capablanca to Kasparov and Carlsen, choose a famous game and start from its decisive position. Play it out for real against a friend through a private invite link, a rating-matched opponent with live clocks, or Stockfish running as WebAssembly in your browser at four strengths. When the game ends you get a match rate against the original moves, a marker at the first move where you diverged, and a practice mode to retry the position.
There is also an ECO-coded encyclopedia of 3,600+ openings, each playable from its resulting position, plus tournaments where a group plays the same positions and compares results.
Free to play with no ads; a Player plan at $4.99/month unlocks the full catalogue. MIT-licensed on GitHub (replay-chess/chess-battle-turbo), built with Next.js 15, React 19, Prisma, Socket.IO and Stockfish WASM; installs as a PWA.
- Who it is for
- Club and online chess players (800-2000) who follow chess history channels, coaches who want to hand a student a specific position, and Next.js developers.
- Problem it solves
- Chess videos pause at the critical position, you find the winning move, and then the narrator plays the rest for you. You never practise converting the position against an opponent who is trying to stop you, and opening study stays a memorised move list.
- The solution
- Every famous position (50+ legends) and every one of 3,600+ ECO openings is playable from its critical/resulting position against a friend, a rating-matched opponent with live clocks, or Stockfish in the browser at four strengths. Afterwards you get a match rate against the original moves and the exact move where you diverged, plus a practice mode.
- What makes it unique
- It is free, ad-free and MIT-licensed (Next.js 15, React 19, Prisma, Socket.IO, Stockfish WASM), and it starts you inside the moment rather than at move one - the divergence report against the grandmaster's line is the core loop, not an add-on.
