It is very much maintained and got it's 1.0 release not long ago. Sadly there is a single guy doing all the work for Ninja so the tempo of releases varies. I also think there is quite a way to the stability of DRF and DRF's ecosystem. If you want permissions and throttling for example you'll have to use django-ninja-extra which is pretty much "DRF but its Ninja".

For me personally I think the micro approach of Ninja / FastAPI is at odds with what I want out of DRF. I just want to make my crud stuff and not worry about implementing e.g. throttling, etc, on my own.
