After I came across OpenAPI in a Nestjs project I thought I was stuck in the stone age with Flask. But after I continued the project I didn’t feel I was missing out too much because I don't build large web apps. Flask with another batteries included framework is a nice combination. In my opinion, they both serve distinct use cases.
