@DasFaultier@sh.itjust.works we've recently deployed Netbox which seems to somewhat do what you want, although its more targetted towards datacenter and network engineers (and maybe not lightweight enough for you?)
If you really need nothing special then maybe a good ol' spreadsheet is a better solution for you.
@ackthxbye@feddit.org Unity Mod Manager has a short linux guide which advises to just run it under mono/wine, where you got the game from should not make a difference
