About Excalidraw
Excalidraw is a free, open-source online whiteboard used to create diagrams, sketches, wireframes, and flowcharts with a hand-drawn style. It runs directly in the browser and allows users to quickly visualize ideas using simple drawing tools like shapes, arrows, text, and freehand sketches.
The tool is popular among developers, designers, and teams for brainstorming, planning systems, and explaining concepts visually. One of its main advantages is its minimal interface and βsketch-likeβ aesthetic, which makes diagrams look informal and easy to understand while keeping the focus on ideas rather than polished design.
Excalidraw also supports **real-time collaboration**, allowing multiple users to work on the same whiteboard through a shared link. Users can export drawings as PNG, SVG, or a `.excalidraw` file and the app automatically saves work locally in the browser. It also supports an infinite canvas, undo/redo, image support, and other diagramming tools.
The project was **founded in 2020** and is developed by a team based in Brno, Czech Republic. Because it is open-source, developers can also embed the Excalidraw editor inside their own apps or self-host it for private use.
