Djangi-ninja is excellent, but it's still Django and when you aren't using a lot of the "batteries included" then you're not really using Django. I mentioned SQLAlchemy which is already "fighting Django" compared to using Django Orm as an example. We picked Litestar because it's natively async, makes it easy to use dataclasses rather than Pydantic, has really fast cold start and it has great interoperability with Advanced Alchemy.

I think Django is great, and by extension that Django-Ninja is too. Considering it runs Instagram it certainly scales as well, but unlike Instagram we aren't enough engineers to be able of ripping out more and more batteries while replacing them with our own specialized batteries.
