Drawbridge

network diagrams · draw.io compatible

Diagrams that route themselves.

Drop in your devices and Drawbridge routes the connections — clean orthogonal lines that hop where they cross and stay clean when you move things around. It opens and saves draw.io files, and your diagrams are saved where you choose rather than in an account of ours.

The drawing in the middle, the tools within reach.

Studio is the layout Drawbridge now opens in. An app bar names the document and switches between the drawing, the page as tables, what is left to finish and the handover pack. The tools float over the drawing, the pages run down the left with a picture of each, and whatever you select is on the right. It comes in six themes, light and dark.

Prefer the layout Drawbridge always had? Classic is one click away, and stays your layout once you choose it.

routing

Connectors route like you’d draw them

Orthogonal routing by libavoid — the lines avoid your shapes, hop where they cross and re-route live while you drag. No waypoint fiddling.

privacy

No account, no tracking

Fully offline after the first visit. No sign-up, no analytics, no telemetry — your diagrams are saved where you choose. Collaborating in the browser relays through us, encrypted and stored nowhere; the privacy page is precise about it.

formats

Speaks draw.io, Visio — and your switches

Opens and saves .drawio files without losing a byte of what other tools wrote, and imports and exports Visio .vsdx. Paste the output of show cdp neighbors or show lldp neighbors and the topology draws itself.
