tldraw
An infinite canvas you can build on
- No reviews yetCategory: Design & MediaUpdated May 2026
tldraw is an infinite-canvas whiteboard and, underneath, a powerful React SDK for building your own canvas apps. The hosted app is great for diagrams and collaboration, while the SDK powers custom tools; its "make real" feature even turns sketches into working UI with AI.
Highlights
- Polished infinite canvas with real-time collaboration
- Embeddable React SDK for custom canvas apps
- The "make real" feature turns sketches into working UI
- Strong developer documentation
tldraw stands out for developers who want to embed a canvas in their own product, not just draw on one — the SDK is its real differentiator. As a plain whiteboard it competes with Excalidraw, which is fully open source and free; as a build surface it is in a class of its own. Choose tldraw when you want to build with a canvas, Excalidraw when you just want to sketch.
