Open-source infinite canvas whiteboard and React SDK for drawing applications

As of 29 August 2026, tldraw is free to use. tldraw is a free, open-source infinite canvas application and SDK for building collaborative drawing interfaces. Softwr lists it under Productivity. tldraw is available on Web.

Overview

What tldraw does

tldraw is both a standalone infinite canvas whiteboard and a developer SDK for building custom drawing applications. The web application provides unlimited canvas space for sketching, wireframing, diagramming, and brainstorming with pressure-sensitive drawing tools (pen, highlighter, eraser), shape tools (rectangles, circles, arrows, text), and basic collaboration. Self-hosted real-time multiplayer using a backend (e.g., using tldraw's cloud sync or custom WebSocket servers) enables teams to collaborate on the same canvas simultaneously. The application supports embedding media (YouTube, Figma, tweets) directly into drawings and includes DOM canvas rendering for accessibility. The underlying tldraw SDK is a React library and TypeScript framework enabling developers to build custom canvas applications (design tools, diagramming platforms, collaboration software) on top of tldraw's drawing engine. Runtime APIs and component customisation allow modifications without forking; custom shapes, tools, bindings, and UI themes integrate seamlessly. AI integration is explicitly supported; developers can build LLM-powered features (auto-layout, image generation, text suggestions) leveraging canvas state. The project is deployed at scale by Shopify, Google, Autodesk, and ClickUp for internal tools and customer-facing features. Dual licensing model: the tldraw application is free, but production SDK use requires a license key. Development is unrestricted; organisations pay for production deployments. This model supports open-source development whilst providing commercial sustainability. The tldraw name and logo are trademarked.

What people use it for

  • Collaborative whiteboarding for distributed teams (internal tool alternative to Miro)
  • Developer SDK for building custom design tools and diagramming platforms
  • Wireframing and UX prototyping applications
  • Integrating drawing capabilities into larger applications (CMS, collaboration tools, learning platforms)
  • AI-powered drawing assistants and generative design tools
  • Educational applications and interactive learning environments

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about tldraw.

  • Production SDK use requires a license key; the dual licensing model means open-source development is free but commercial deployments are not
  • Limited ecosystem of community plugins; third-party extensibility less mature than some competitors
  • Multiplayer functionality requires custom backend implementation; real-time sync is not fully managed by tldraw
  • Mobile touch experience is functional but less optimised than desktop; precision drawing on tablets is challenging

Cross-shopped

What people choose instead of tldraw
