Common Questions

Is the network diagram builder actually free, or is there a paid tier?

It's fully free with no signup required. Drag devices onto the canvas, draw connections, label everything, and export as a PNG โ€” no account, no paywall.

Does the diagram data get saved or sent anywhere?

No. Everything runs in your browser โ€” nothing is uploaded or stored on our servers. Export your diagram as a PNG when you're done, since closing the tab clears the canvas.

When would I actually need a network diagram?

It's useful before an IT assessment, when onboarding a new IT provider so they understand your setup quickly, or simply to document what you have when nobody's quite sure anymore.
