Fast to develop, not necessarily as fast as a 'written and optimized by hand' UI.

Have you used FastAPI? Certain functionality like file upload is mind blowingly slow.

FastX is popular these days.

I have trouble finding the FastX project you mentioned. Can you tell me its website?

The top results I get are for the Fast and Furious movie. After specifying the context ("API", "web", "framework") I get hits for remote desktop software which also has API:

https://www.starnet.com/fastx/ https://www.starnet.com/help/fastx-v3-api/

And "fastx python" returns a module for parsing FASTA files

https://pypi.org/project/pyfastx/

Sorry for the confusion. I just meant, naming something "Fast" and then a descriptor, has become very popular.

FastHTTP, FastGPT, FastChat, FastAI, FastLED, FastText, FastClick, FastHub, FastSAM

Most of these have 10s of thousands of stars on github.

Anyone have experience with Django Ninja?
