I built a free tool to automatically generate Azure network diagrams

Hi HN,

I'm Kristoffer, a cloud security architect. I built CloudNetDraw to solve a problem I kept running into: diagramming Azure networks manually is slow, error-prone, and annoying.

This tool connects to your Azure environment (via user login or service principal) and auto-generates Draw.io diagrams of your vNets, peerings, subnets, and even flags NSGs and UDRs. It supports both HLD and MLD, and exports clean, editable files.

Privacy-wise, nothing from your environment is stored — diagrams are generated in memory and deleted right after download.

You can use the hosted version, or self-host it in your own tenant (it's open source, no tracking).

Would love feedback, suggestions, or just to hear what people think.
