PixelForge is a browser-based collaborative design tool that enables real-time multiplayer editing with zero latency perception. Built using the Canvas API for rendering and WebSocket/CRDT for conflict-free real-time sync. Features include a component library system, auto-layout engine, design tokens, and one-click export to React/HTML code. The backend uses Go for the WebSocket server and Redis for pub/sub messaging between connected clients. The project handles 50+ concurrent editors on a single canvas while maintaining 60fps rendering performance.
