Overview
Excalidraw is an open-source virtual whiteboard for hand-drawn-style diagrams, sketches, wireframes, presentations, and visual notes. The editor uses an infinite canvas, supports editable scene files, and is also distributed as a reusable React component for embedding in other applications. Excalidraw+ adds workspace collaboration, text-to-diagram and wireframe-to-code generation, bring-your-own-key options, and an MCP connection for AI agents that can work with scenes. The main Excalidraw repository is MIT licensed; the hosted Plus features are proprietary. The editor can also run self-hosted.
