About
Chessify is a cloud-based chess analysis and training platform that gives players access to the world's fastest chess engines without requiring expensive local hardware. Powered by Stockfish 18, Stockfish 17.1, Leela Chess Zero (LCZero), and a suite of other top engines, Chessify delivers analysis speeds of up to 1,000,000 kN/s on its premium cloud servers — far beyond what most personal computers can achieve. Registered users get free analysis at up to 1,000 kN/s using multiple engines including Stockfish, asmFish, SugaR, Koivisto, Berserk, and more. PRO subscribers unlock faster cloud servers, with Stockfish reaching up to 1 BN/s. The platform integrates with popular desktop chess GUIs — including ChessBase, Fritz, HIARCS, and SCID — via a dedicated plugin, making it easy to slot into existing workflows. Chessify also includes a continuously updated online database of over 9.7 million games for opening preparation and opponent research, a 6-piece Syzygy endgame tablebase for perfect endgame play analysis, and encrypted cloud storage for saving games and analysis. The web interface provides training statistics, engine management, and access to all features from any browser. Endorsed officially by FIDE and used by hundreds of grandmasters, Chessify is ideal for professional players, serious club players, chess coaches, and enthusiasts who want world-class analysis power without investing in dedicated hardware.
