Description
A free, open-source diagram canvas: MIT, local-first, no account, in your browser. One canvas, five ways in. Draw it. Write it as code, or paste Mermaid, D2 or Structurizr. Ask any of 10 AI providers, or a local model. Hand it to your coding agent: Claude Code edits the canvas you have open, live, over MCP. Or pull it from a GitHub repo, every arrow citing its file and line. The CLI checks drift in CI, so diagrams keep up with your code.

Could you build this?
Yes Canvas-based diagramming tools that render DSLs like Mermaid or D2 and integrate with LLMs or coding agents via standard protocols are well-supported by open-source libraries like Excalidraw, tldraw, and MCP.
