tldraw
A free online infinite-canvas whiteboard for sketches and diagrams, built on the tldraw React SDK, which developers can use to add a canvas editor to their own apps under a separate license.
The same engine behind a polished public whiteboard is a programmable canvas you can drive from code, shape by shape.
Commercial: conditionsFor your project
- Official API
- No official API
- Data download
- No bulk download found
- License
- tldraw license (SDK, source-available) tldraw SDK: free only in development; production needs a trial, commercial or hobby license key (hobby keeps the 'made with tldraw' watermark). Terms for drawings made on tldraw.com were not readable.
- Commercial use
- Commercial use with conditions
“Commercial licenses remove the watermark and are required for any commercial use in production.” tldraw.dev/sdk-features/license-key
- Credit
- Credit depends on the item
“Hobby licenses keep the "made with tldraw" watermark visible.” tldraw.dev/sdk-features/license-key
- Embedding

For your agent
No official API. An agent should not scrape the site: use it by hand.
- Official npm package 'tldraw' (start with 'npm create tldraw@latest'); source is on GitHub (github.com/tldraw/tldraw) but under the source-available tldraw license, not open source: free in development, while any production deploy needs a license key (trial 100 days, commercial, or hobby with watermark) or the editor stops rendering; tldraw sync is a self-hostable collaboration backend.
- Do not ship the SDK to production without a valid license key
- Commercial production use needs a commercial license; hobby licenses must keep the 'made with tldraw' watermark
- Do not describe the SDK as open source; it is source-available

What you can build
- A prototype whiteboard inside an internal tool, built in development and licensed before going to production
- An agent-driven diagram editor where an LLM places and edits shapes through the SDK's Editor API
- A hobby (non-commercial) visual note app that keeps the 'made with tldraw' watermark
