Title: What's actually on your network right now? (not a trick question)

Launching NetLanvas here today — it's a self-hosted tool that builds a live topology map of your network automatically: every device, every link, every VLAN, kept current without you doing anything. On top of the mapping, it runs standing security checks most networks never get audited for — default/public SNMP community strings still enabled, exposed management interfaces, unverified access points, devices that show up with no explanation.

It's open source (Apache 2.0) — github.com/markeaster/NetLanvas — runs on Docker (a Pi handles it fine) or as a native Windows/macOS install. There's a live read-only demo if you want to poke around before installing: demo.netlanvas.com

Curious what this crowd runs today for network visibility — dedicated NMS, a spreadsheet, nothing? And what would make a topology/security tool actually worth installing vs. just living with router admin pages one device at a time.
