About ExcaliClaw
ExcaliClaw is an independent workspace for organizing, sharing and collaboratively creating hand-drawn diagrams. Every drawing is saved automatically, organized into collections, searchable by name and shareable by public link or by username. It is operated independently and is not affiliated with any other drawing tool.
Who it's for
- Engineering teams that keep architecture and flow diagrams in one searchable place.
- Product and design teams that sketch together in real time.
- Anyone who wants a free online whiteboard: try it without an account and nothing is stored on the servers.
- People who work with AI agents and want them to draw diagrams directly.
What it includes
- Persistent storage, collections and instant search.
- Real-time collaboration with live cursors.
- Sharing by public read-only link or by user, as viewer or editor.
- Export to JSON and import from other tools, such as Miro.
- MCP tools for AI agents such as Claude, Cursor and VS Code.
The interface is available in English, Spanish and French. Contact: support@excaliclaw.com.
