Why Teams Choose Excalidraw
Excalidraw's hand-drawn aesthetic is not just a style choice — it signals to collaborators that the diagram is a work in progress, encouraging feedback rather than polished finality. This psychological effect has been documented in UX research and is cited by Excalidraw's creator as a deliberate design decision. The tool is fully open-source under the MIT license, and the codebase has over 80,000 stars on GitHub.
End-to-end encryption ensures that collaborative sessions are private by default — the server never sees your diagram contents. Libraries of reusable shapes are available for wireframing, system architecture, and flowcharting. Excalidraw integrates with VS Code, Obsidian, and Notion through community plugins.
