If you work in IT with multiple client networks to keep track of, or you just have a lot of personal internet-connected devices around the place, NetBox looks like an awesome tool for interactive documentation!
I’ve only just come across it recently, but I am definitely keen to try it out for my own stuff.
It was originally developed as an internal tool at Digital Ocean (one of the big online cloud server hosts), and they released it to the public as an Open Source project 6 years ago.
