CloudNet-Draw – Automatically generate Azure network diagrams (opens in new tab)

I’m a Cloud Security Architect, and I built this tool to solve a very specific pain: every time I started a new project, I had to manually create a network diagram of the Azure environment — hubs, spokes, peerings, subnets, NSGs, UDRs, etc.

It was repetitive and error-prone. So I made CloudNet-Draw.

It’s a Python-based CLI that queries Azure via the API and outputs a .drawio file representing the full virtual network topology — no manual drawing required.

It’s free and open source — no telemetry, no cloud backend. Just Python and Azure SDK.

Would love to hear what you think, and happy to take feature ideas or feedback.

Thanks!
