Agent-powered diagram generation from codebases beats manual C4 modeling.
First tool I've seen with a public MCP server specifically for 12V wiring diagrams.
Another AI architecture tool competing directly with established players like Lucidchart and Hava.
Napkin keeps everything local while giving you an embeddable MCP endpoint so AI agents can draw and edit diagrams at http://127.0.0.1:21420/mcp. It combines Excalidraw-style hand-drawn tooling (rough.js, connectors, grid snapping, PNG/SVG export) with a Tauri/Rust desktop shell and delta-compressed version snapshots — a neat, concrete take on AI-assisted diagramming, though its impact hinges on MCP adoption and the surrounding agent ecosystem.
LZ-compressed URLs encode entire diagrams — no backend needed for sharing.
Another AI diagram generator when Mermaid AI and Lucidchart already exist.
