ExcaliClaw
ExcaliClaw is an independent browser-based workspace for organizing, sharing, and collaboratively creating hand-drawn diagrams. It combines persistent cloud storage, collections, search, real-time collaboration, sharing, and MCP tools that let AI agents such as Claude, Cursor, and VS Code create and edit diagrams in a user's workspace.

Products & Services
Browser-based workspace for hand-drawn diagrams with automatic persistent saving, collections, instant search, real-time collaboration with live cursors, sharing by public link or username, JSON/PNG/SVG export, and import from other tools such as Miro.
Remote Streamable HTTP MCP endpoint at https://excaliclaw.com/mcp. It lets supported AI clients create flowcharts, architecture diagrams, ER diagrams, notes, and raw designs; manage collections and versions; export PNG/SVG; reuse library components; and edit live scenes.
Market Position
ExcaliClaw positions itself between quick/open-source sketch boards and full-featured collaborative whiteboards: unlike Excalidraw, tldraw, and Dia it emphasizes persistent searchable cloud organization and collaboration; unlike Miro and FigJam it focuses on hand-drawn diagrams and does not provide workshop tooling such as voting, timers, or large template libraries. Its differentiator is a hosted MCP server with structured, layout-aware, validated tools for AI agents, while draw.io and Lucidchart are positioned as better fits for precise/formal diagrams or paid business diagramming.
