Excalidraw — Free & Open Source for Startups

Deal Highlights

Excalidraw — Virtual Whiteboard for Sketching Ideas Fast

Excalidraw is a free, open-source virtual whiteboard for creating hand-drawn style diagrams. Architecture diagrams, user flows, wireframes, and brainstorming sessions — all with a sketchy aesthetic that keeps things informal and collaborative.

Why Hand-Drawn Style

Polished diagrams signal "this is final." Hand-drawn diagrams signal "this is a draft — let us discuss." Excalidraw deliberately uses a sketchy style that encourages iteration and feedback instead of premature polish.

Real-Time Collaboration

Share a link and collaborate in real-time. Multiple people draw, annotate, and rearrange simultaneously. No accounts required for collaborators — just share the URL.

Libraries and Components

Pre-built shape libraries for system architecture, UX wireframes, flowcharts, and more. Import community libraries or create your own reusable components.

Excalidraw vs Miro
