Excalidraw Whiteboard
Excalidraw is a virtual collaborative whiteboard tool that lets you easily sketch diagrams that have a hand-drawn feel to them.
Categories:
Excalidraw is a free open-source virtual whiteboard for sketching hand-drawn like diagrams with real-time collaboration and end-to-end encryption.
๐ Overview
Excalidraw solves the problem of complex diagramming tools by offering a simple, intuitive infinite canvas for quick sketches, wireframes, flowcharts, and brainstorming sessions that look hand-drawn.
It's built for developers, designers, educators, teams, and anyone needing fast collaborative diagramming without sign-ups or heavy software. The project is embeddable as a React component and works offline as a PWA.
The creators built it to provide a lightweight, privacy-focused alternative that's extensible and runs everywhere with a browser, prioritizing speed and simplicity over feature bloat.
