tldraw is built on its own open-source @tldraw/tldraw React component and TypeScript SDK, available on npm. The canvas engine uses a custom renderer optimized for infinite, high-performance vector drawing. Real-time collaboration is powered by a CRDT-based sync engine (@tldraw/sync) that supports self-hosted backends via WebSocket. Developers can embed tldraw into any React application, extend it with custom shapes and tools, and hook into a rich event/store API. The project also exposes a makeRealApi for integrating generative AI features directly into the canvas.
