BaugraphArchitecture diagrams that live in your repository

A browser-based diagram editor for flows, queues and integrations. Diagrams are plain JSON, designed to be committed next to the code they describe.

Diagram as code

A diagram is one .baugraph.json file — node ids from labels, defaults omitted, keys in a fixed order — so a diff shows exactly what changed and nothing else.

Rich node catalogue

~90 node types and ~250 technologies, grouped by category and searchable from the palette, context menu and inspector alike.

Zones and grouping

Wrap nodes in labelled, nestable zones — a VPC, a cluster, a bounded context — and move the group as one.

Animated message flows

Send a message along a path that multiplies at every fork, with per-connection style overrides and reduced-motion support.

Everything stays local

Runs entirely in your browser. No account, no server-side storage, nothing uploaded.

Export that matches the screen

SVG (with the flows animated via SMIL) and PNG exports share the same shape, routing and colour code as the canvas.
