tldraw - A library for creating infinite canvas experiences in React. It's the software behind the digital whiteboard tldraw.com.

Build infinite canvas apps in React with the tldraw SDK.

Feature highlights

tldraw provides a feature-complete infinite canvas engine designed to be the foundation for any canvas app. Create custom shapes, tools, bindings and UI components for a custom experience. Use the default whiteboarding tool set or use the library's primitives to build entirely new shapes and interactions.

Multiplayer — self-hostable real-time collaboration with @tldraw/sync
Drawing and diagramming — pressure-sensitive drawing, geometric shapes, rich text, arrows, snapping to shapes, edge scrolling, image and video support, image export
Runtime API - drive the canvas at runtime with the Editor API
Fully extensible — custom shapes, tools, bindings, UI components, side effects, and event hooks
AI integrations — canvas primitives for building with LLMs
DOM canvas — web rendering supports anything the browser supports, including embedded websites from YouTube, Figma, GitHub, and more
Broad support — works in any browser across desktop, touch screens, tablets, and mobile devices

Quick start

Install the tldraw package:

npm i tldraw

Then, use the <Tldraw /> component in your React app:

import { Tldraw } from 'tldraw'
import 'tldraw/tldraw.css'

export default function App() {
	return (
		<div style={{ position: 'fixed', inset: 0 }}>
			<Tldraw />
		</div>
	)
}

Starter kits

Starter kits provide the custom shapes, tools, and user interface needed for common applications. Each kit is MIT-licensed. Hack together a prototype, build out an app on top, or reference the code in a larger project.

Start building with:

npx create-tldraw@latest

Multiplayer — self-hosted real-time collaboration powered by @tldraw/sync and Cloudflare Durable Objects, the same stack behind tldraw.com
