Problem
Developers building interactive whiteboards, diagram editors, or visual collaboration tools must implement complex canvas infrastructure, real‑time synchronization, undo/redo, and performance optimizations from scratch, which consumes significant engineering time and introduces reliability risks.
Solution
tldraw offers an infinite‑canvas SDK for React that delivers a production‑ready foundation for any visual canvas application. The SDK includes enterprise‑grade multiplayer sync, conflict‑free collaboration, automatic persistence, and high‑performance rendering optimized for thousands of shapes. It ships with a comprehensive library of default shapes, tools, and UI components, as well as a full runtime API that lets developers customize shapes, interactions, themes, and user interfaces programmatically. By handling data management, asset optimization, and real‑time networking out of the box, tldraw lets teams focus on domain‑specific features rather than low‑level canvas engineering.
Target Audience
Primary customers are product teams and developers building collaborative whiteboards, diagram editors, workflow builders, or AI‑enabled visual tools that require real‑time canvas interaction within React applications.
