Flask is missing... pydantic, dependency injection, openapi, swagger, real async.

But there are definitely options for Flask if you want to use async.

  flask-openapi3 looks good but has only 246 stars. Would be worried using it in production. flask-pydantic has no openapi tie-in. Oh look, there's me bumping the openapi request that's been an issue since 2020: https://github.com/pallets-eco/flask-pydantic/issues/17 https://github.com/pallets-eco/flask-pydantic/issues/17 which has an open PR since 2022. It's possible between Quart and svcs (for DI) and some Pydantic/Marshmallow/OpenAPI extension you might be able to mimic what FastAPI does. But I'd just use FastAPI. I use async too. It's a lot easier to scale in my opinion. Do none of these pieces matter to you? Like do you not do any data validation or care about OpenAPI?

    At $JOB we're using both flask-pydantic and flask-openapi via those libraries and they are serving us just fine. But yes async does not matter to me.

  Of course you can assemble FastAPI scrim scratch, that’s not the point. The selling point is everything integrated, like Django.

So nothing of importance.

  What do you do for data validation?

Dependency injection in fastapi honestly feels like a horrible afterthought. Flask's g is much easier to reason about, and 99% of projects don't need the 'performance improvements' of async.
