What is tldraw?

tldraw is a free, open-source infinite canvas application designed for drawing, diagramming, and virtual whiteboarding. The tool allows users to create and collaborate on visual content without requiring account registration or setup. The platform works across devices including desktop computers, tablets, and mobile phones, making it accessible whether users are working from a desk or on the go. Its infinite canvas feature enables users to expand their workspace in any direction, supporting projects that grow beyond traditional fixed-size documents. tldraw is suited for teams and individuals who need to sketch ideas, create diagrams, build wireframes, or conduct remote brainstorming sessions. The collaboration capabilities allow multiple users to work on the same canvas simultaneously, making it useful for distributed teams or group design sessions. As an open-source project, tldraw's source code is publicly available for inspection and modification. The tool emphasizes simplicity and instant access—users can begin drawing immediately without navigating signup flows or account management steps. This approach reduces friction for casual users while maintaining functionality for more complex collaborative workflows. The combination of no-login access, cross-device compatibility, and collaborative features positions tldraw as a straightforward alternative to more feature-heavy design and whiteboarding tools.
