I like netbox, had it deployed for quite a while. It's performance was abysmal and I had to shape my world around how they wanted things.

This is the usual case of "We need X and Y does X", but ignoring that Y also does Z,M,Q and washes dishes and you really don't need those things.

Sometimes building what you need is the easiest solution, specially when what you need is CRUD infront of a DB...
