Free Chess Tools, Built for Players
AnkouChess is a free chess analysis platform powered by Stockfish. No ads, no paywalls — just fast, accurate tools for every level.
Our Mission
We believe every chess player deserves access to world-class analysis tools, regardless of budget. AnkouChess was built to close the gap between expensive subscription platforms and the quality of analysis players actually need to improve.
Stockfish — the world's strongest open-source chess engine — runs entirely in your browser via WebAssembly. Your games never leave your device. No server processing, no data collection, just pure analysis.

Our Approach to Chess Content
Every opening guide, article, and puzzle description on AnkouChess is written with accuracy and practical value in mind. We reference established chess theory, draw on master-level games, and verify strategic claims against engine analysis.
Our opening database covers 146 variations with ECO classifications, difficulty ratings (beginner to master), and opening type categorizations (open, semi-open, closed, hypermodern). Content is reviewed and updated as chess theory evolves.
AnkouChess is used by players from beginner to club level in over 50 countries. We publish a regular chess blog covering tournament news, improvement guides, and opening theory — all freely accessible without registration.
Technology
AnkouChess uses Stockfish, the world's highest-rated chess engine, compiled to WebAssembly so it runs at full strength directly in your browser. This means:
- Analysis is instant — no waiting for server responses
- Your games stay private — nothing is uploaded or stored without your consent
- The engine works offline once the page is loaded
- Analysis depth scales with your device's processing power
The platform is built with Vue 3 and Quasar Framework, with a Node.js backend for puzzles, tournament data, and the openings database. We use Server-Side Rendering (SSR) for fast initial load times and full SEO compatibility.
