Network diagrams that route themselves
Drawbridge is a free editor for network architecture diagrams. Drop in
your devices and it routes the connections for you: clean right-angled
lines that keep clear of your shapes, jump where they cross, and
re-route while you move things around.
It opens and saves draw.io files without losing anything 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.
Your diagrams stay yours. There is no account, no ads, no analytics and
no tracking. Files are saved where you choose, and the app works fully
offline. Work on the same drawing live with a colleague: the desktop app
collaborates peer to peer.
