The Top Features to Look for in a Modern Chess Analysis Website
In 2026, a static board isn't enough. Discover the must-have tools that separate amateur analysis from professional preparation.
Stockfish WebAssembly (WASM)
Run the world's strongest engine directly in your browser. No server lag, total privacy.
Interactive Repertoire Lab
Build and sync your opening preparation to the cloud via Cloudflare D1.
Seamless Platform Imports
One-click import from Lichess and Chess.com using public APIs.
Responsive Board Design
A native, 100% stable board experience on both mobile and desktop.
Why Privacy Matters in Analysis
When you analyze a game on legacy servers, your prep is stored on their databases. Modern platforms like Plychess use Client-Side Engine Calculation. By leveraging WebAssembly, we ensure that your novelties and secret opening lines never leave your browser until you choose to sync them to our encrypted D1 database.
The Advantage of Dual-Interaction Boards
The best chess sites now support both Click-to-Move and Drag-and-Drop. This isn't just about preference; it's about speed. During rapid analysis, clicking a piece to see legal moves (highlighted by our native dot system) prevents mouse-slip errors that can ruin a FEN position.
