Excalidraw
Sketch ideas, plan a room, or explain something with a simple hand-drawn whiteboard.
Why it’s here
An approachable canvas for sketching everyday ideas and sharing them as drawings.
Before you install
- macOS with PicoRunner
- Internet access for installation
- Pinned source declares Node 18 or newer and Yarn 1.22.22

License: MIT
What has been checked
Runtime verified
Checked 2026-09-22 on macOS arm64 with PicoRunner 0.3.0. Later upstream changes may affect compatibility.
Reviewed source: 31df3e6ef245. The installer currently downloads the default branch; this is not a pinned install.
- Evidence: MIT license confirmed at the checked commit
- Evidence: Root package excalidraw-monorepo declares start = yarn --cwd ./excalidraw-app start. Package manager: yarn@1.22.22. Exact manifest verified; installation not tested.
- Evidence: Upstream source and setup documentation reviewed. Transitive dependencies, external connections and macOS runtime behavior have not been exhaustively verified.
- install: Installed from the live PicoRunner Discover catalog into a new managed folder with bundled runtime tools.
- launch: Started successfully using yarn run start and opened the Excalidraw Whiteboard.
- health: HTTP 200 verified on the app's localhost address after restart.
- smoke: Created a rectangle in the browser canvas and undid it; the prior drawing remained unchanged.
- restart: Restarted through PicoRunner twice. First restart recovered a conflict with an unrelated IPv4 listener; the second retained the uncontested address and rendered the canvas.
- cleanup: Stopped and deleted only the disposable test installation through PicoRunner. Managed folder removal was verified; both pre-existing imported apps remained.
