仕組み

  1. Open the app

    No install at all for the hosted editor: go to excalidraw.com and start drawing — work is saved locally in your browser.

  2. Share or collaborate

    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.

  3. Self-host or embed it

    Clone the repo to run your own instance, or embed the editor in a React app with the @excalidraw/excalidraw npm package.

// 機能

選ばれる理由

Hand-drawn aesthetic

The sketchy style is a feature: diagrams look like drafts, so teams actually edit them instead of treating them as finished art.

Real-time collaboration

Live multi-user rooms with end-to-end encryption — the server cannot read shared boards.

Embeddable editor

The npm package drops the full whiteboard into your own product, with an API for scenes, elements and app state.

Libraries and exports

A public library of reusable diagram elements, plus PNG, SVG and native-file export for portability.

// 自分で実行

自分で実行してみる

  1. Use it in the browser

    The zero-install route — the full editor, free, no account needed.

    https://excalidraw.com
  2. Self-host from source

    Per the README development setup (Node + yarn).

    git clone https://github.com/excalidraw/excalidraw.git
    cd excalidraw
    yarn install
    yarn start
  3. Embed it in a React app

    The editor as a component, from the README.

    npm install react react-dom @excalidraw/excalidraw

// よくある質問

よくある質問

Who makes Excalidraw?

The Excalidraw open-source community (excalidraw/excalidraw on GitHub); the hosted excalidraw.com service and the Excalidraw+ product are run by the core team.

Is Excalidraw free?

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.

Is my data private?

Files you keep locally never leave your machine, and shared collaboration rooms are end-to-end encrypted, so the servers only relay ciphertext.

How does it compare to a well-known alternative?

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.

How do I get started?

Open excalidraw.com and draw. To self-host, clone the repo, yarn install, yarn start.
