Excalidraw
Hand-drawn Excalidraw JSON diagrams (arch, flow, seq).
Create diagrams by writing standard Excalidraw element JSON and saving as `.excalidraw` files. These files can be drag-and-dropped onto [excalidraw.com](https://excalidraw.com) for viewing and editing. No accounts, no API keys, no rendering libraries -- just JSON.
Platforms: linux, macos, windows.
