tldraw is a free, source-available collaborative whiteboard and diagramming tool that provides an infinite canvas for sketching, wireframing, and visual thinking directly in the browser. It solves the need for a lightweight, instantly accessible drawing tool that feels natural and responsive, without requiring account creation or complex setup. tldraw combines the simplicity of a whiteboard with the precision of a vector editor, making it ideal for quick diagrams, UI sketches, and collaborative brainstorming sessions.
tldraw features a minimal, distraction-free interface with essential drawing tools including freehand lines, shapes, arrows, text, sticky notes, and image embedding. It supports real-time multiplayer collaboration, infinite canvas with smooth zooming and panning, shape snapping and alignment, and export to SVG, PNG, and JSON formats. As a source-available React library, tldraw can be embedded into any web application, and its extensible architecture allows developers to create custom shapes, tools, and behaviors tailored to specific use cases.
tldraw is used by developers, designers, product managers, and educators who need a fast and frictionless way to visualize ideas, create diagrams, or collaborate visually. It is particularly popular as an embeddable component in developer tools, documentation platforms, and collaborative applications. The tldraw SDK integrates into React applications with minimal configuration, and its permissive license and active development community make it a top choice for teams building custom whiteboarding or diagramming features into their own products.
