The Chess Database With +10M Games
CipherChess is a free online chess database of over 10 million games, spanning 1475–2026 — from club players to world champions. Search the database by position, by player or by opening, apply advanced filters, and replay any game move by move. No download, no install — the entire chess database runs in your browser.
What the database can do
Search by Position
Set up any position and instantly see every game in the database that reached it — and which moves were played next, with win, draw and loss rates.
Search by Player
Type any name to pull a player's entire game history, record and favourite openings. The fastest way to scout your next opponent.
Advanced Filters
Narrow the database by ECO code, rating, result, event, year and time control to isolate exactly the games you want to study.
Opening Explorer
Walk any opening move by move and see real statistics from millions of games: popularity, scoring and the top replies at every turn.
Replay & Analyze
Step through every game on an interactive board, then send it to the Stockfish engine for a full move-by-move review.
Build a Repertoire
Turn what you find in the database into a navigable opening repertoire tree, then train it until it's muscle memory.
A chess database built for study
Most chess databases were built for desktop software a decade ago. CipherChess rebuilds the online chess database around the way players actually study today: open a browser tab, search 10M+ games, and go straight from a position to a plan. Whether you are researching an opening, preparing for a tournament, or settling a debate about a famous game, the database puts the answer one search away.
Every game in the database is fully indexed by position, so you are never limited to searching by name. Drop into any middlegame or endgame structure and the database shows you how the strongest players handled it — the most popular continuations, the scoring for each side, and the games where the plan succeeded or failed.
Combine that with advanced filters — ECO code, player rating, result, event and date range — and the 10-million-game database becomes a precision research tool. Find every Najdorf won by a 2700+ player since 2018, or every game your next opponent has lost as Black, in seconds.
A free online chess database — no downloads
CipherChess is a free chess database that runs entirely in your browser, on any device. There is nothing to install and no subscription to search the games — a genuine, modern ChessBase alternative and 365Chess alternative that loads instantly and stays in sync wherever you study. Where legacy desktop chess databases lock millions of games behind paid software, this online chess database opens them to anyone with a link.
Under the hood every game is stored with its full move list, players, ratings, event and ECO opening code, then indexed by position so the database can answer position, player and opening queries in milliseconds. The result is a master games database that feels less like an archive and more like a live research assistant for your chess.
From opening research to opponent prep
Use the database to research an opening from both sides: open the opening explorer, follow the main lines, and see exactly how grandmasters and club players have scored at every branch. Then turn those lines into a repertoire you actually remember.
Or use it to scout your next opponent: search chess games by player name, study the openings they repeat, spot the structures where they slip, and walk into your next round already knowing their plans. From opening preparation to opponent preparation, it is one chess database doing the work that used to take three separate tools.
