Today we're releasing the tldraw SDK 4.0, the fourth major release of our infinite canvas SDK. This release comes with new starter kits, including the Cursor-for-tldraw agent starter, license changes, and a major accessibility milestone.
Find the full details in our announcement post, or get the breakdown below. https://tldraw.dev/blog/tldraw-sdk-4-0
To use a starter kit, run "npm create tldraw@latest" and pick the one you want.
1. The workflow starter kit gives you a production-ready workflow builder.
Add custom node components. Change their appearance and behavior. Connect them to external APIs, automations, or anything you like.
2. The agent starter kit provides an agent that can inspect and change things on the canvas.
Customize any aspect of what the agent can see or do to tailor it to your own app.
3. The multiplayer starter kit adds real-time, self-hosted collaboration using tldraw sync.
4. The chat starter kit puts an inline canvas into a chat application so users can draw, add markup and include additional context to regular chat messages. Every AI chatbot should have this. Show your boss. Tag @cursor_ai and tell them to put the canvas in the chat ffs. Ask for tldraw by name.
5. The branching chat starter kit features a threaded AI chat where the user can branch off from the conversation in multiple directions.
We built this on top of our workflow starter kit in an afternoon!
In addition to starter kits, this release completes the months-long effort to make the tldraw SDK compliant with WCAG 2.2 AA. Paperwork coming soon.
In practice, this means better keyboard controls and a clearer, more customizable UI, and accessibility improvements for all of our users and customers.
We've also updated our licensing model for the tldraw SDK. From 4.0 forward, the SDK will require a license key to work in production. You can grab a free 100-day trial license at Non-commercial projects may apply for a hobby license for unrestricted use.
