Excalidraw
Verified working Oct 3, 2026
A browser whiteboard for quick, sketch-style diagrams with collaborators.
Excalidraw is a web-based collaborative whiteboard for drawing diagrams and visual notes with an informal, hand-sketched look. It is suited to fast visual thinking, lightweight planning, and shared diagramming sessions rather than polished design production.
Why it stands out
- Distinct sketch-like rendering makes diagrams feel approachable and unfinished in a useful way.
- Focused on quick diagramming rather than a heavy all-purpose design workspace.
- Collaboration is built into the core whiteboard use case.
- Runs directly in the browser without requiring a desktop diagramming suite.
Good to know
- Requires JavaScript to run in the browser.
- The intentionally hand-drawn style may not fit formal diagrams that need a polished corporate look.
- Best suited to diagrams and whiteboard sketches, not full document layout or advanced design workflows.

Product teams, educators, and developers can quickly turn rough ideas into shared visual diagrams. Sketch a system architecture or workflow during a remote meeting. Map out lesson concepts, brainstorms, or project plans on a shared canvas. Create informal diagrams that feel closer to marker-board sketches than presentation graphics.
Collaborative virtual whiteboard, freeform diagram sketching, hand-drawn visual style, browser-based canvas for fast visual ideation.
