In a past job of a fairly decent sized org (around 80 engineers, maybe 10 different active projects, a few dozen microservices, component library, template generators, and some custom CLTs) it was very useful as a way of documentation for your engineers.

I'm sure you used stuff like confluence but it was always a terrible way to search across code bases and projects to understand how they worked.

Backstage was interactive documentation. I can see what projects we have, I can click on one, see who is maintaining it, what their communication is, what their various perf/benchmark scores were. It was nice.

Apparently it's even grown beyond documentation needs from what I can tell and it provides platform tooling now.
