The only canvas you'll ever need
tldraw gives design tools, AI image platforms, and creative apps a production-ready React canvas with multiplayer, custom shapes, and a full editor API.
Why tldraw
Built for the apps designers reach for.
Pixel-quality interactions
Selection, drawing, snapping and transformation that designers expect. The same engine that ships on tldraw.com, used by millions


Custom shapes for anything
Annotations, layers, frames, nodes, asset cards. Build the primitives your product needs without rebuilding the canvas underneath them.

No brand constraints
Implement tldraw to look exactly how you need it to and to behave how your clients - and even clients’ customers - expect it to.
Get Started
Two lines of code, a multiplayer canvas, and the same architecture that powers tldraw.com (http://tldraw.com).
What tldraw enables
Annotation & Markup
Underpin your tool with a canvas to allow users to annotate screenshots, mark up references, sketch over images or comment in place. Same primitives whether the source is a PNG, a PDF or even a 3D snapshot.
AI prompting on a canvas
Drop image and text shapes onto the canvas, wire them together, and feed structured prompts to your model. And immediately get to work on the output, generated directly on the canvas in editable form.
"We chose tldraw because we can really see ourselves continuing to build in the long term with it. It's very extensible."

Issue tracker
Jam’s browser extension gives developers an instant solution for reporting bugs. With one click, Jam creates a shareable bug report with all of the technical context—console logs, network requests, device info—as well as a screenshot that a user can annotate to show what’s wrong.
