View guide →Excalidraw — the virtual whiteboard with the hand-drawn look: infinite canvas, real-time collaboration and end-to-end encrypted sharing, MIT-licensed
Excalidraw is an open-source design project by excalidraw (excalidraw/excalidraw on GitHub). It has 134,043 GitHub stars and 15,703 forks, is released under the MIT license, and was last updated on GitHub on 15 October 2026.
No install at all for the hosted editor: go to excalidraw.com and start drawing — work is saved locally in your browser.
Export to PNG/SVG for documents, or start a live session and send the link; collaborators join in the browser and shared content is end-to-end encrypted.
Clone the repo to run your own instance, or embed the editor in a React app with the @excalidraw/excalidraw npm package.
The sketchy style is a feature: diagrams look like drafts, so teams actually edit them instead of treating them as finished art.
Live multi-user rooms with end-to-end encryption — the server cannot read shared boards.
The npm package drops the full whiteboard into your own product, with an API for scenes, elements and app state.
A public library of reusable diagram elements, plus PNG, SVG and native-file export for portability.
The zero-install route — the full editor, free, no account needed.
https://excalidraw.comPer the README development setup (Node + yarn).
git clone https://github.com/excalidraw/excalidraw.git
cd excalidraw
yarn install
yarn startThe editor as a component, from the README.
npm install react react-dom @excalidraw/excalidrawThe Excalidraw open-source community (excalidraw/excalidraw on GitHub); the hosted excalidraw.com service and the Excalidraw+ product are run by the core team.
Yes — the editor is MIT licensed and excalidraw.com is free to use. Excalidraw+ is an optional paid tier with team workspaces and admin features.
Files you keep locally never leave your machine, and shared collaboration rooms are end-to-end encrypted, so the servers only relay ciphertext.
Against tldraw, Excalidraw is the finished product with the bigger library ecosystem; tldraw leans further into being an SDK. Against Miro or FigJam, Excalidraw is free, open source and far lighter — at the cost of their enterprise template and management layers.
Open excalidraw.com and draw. To self-host, clone the repo, yarn install, yarn start.
