gunicorn VS hypercorn

I'm hoping so – gunicorn has a long-open pull request that would fix `--reuse-port`, which currently does nothing

https://github.com/benoitc/gunicorn/pull/2938

However, I'm curious about the best way to deploy, specifically with regard to WSGI. I've tried using the raw eventlet WSGI server (`eventlet.wsgi.server(eventlet.listen(("", 8000)), application)`). I then start it with `python manage.py runserver`. This has worked okay, but I'm unsure about how scalable it is. It seems like the standard stack is Django + Gunicorn + NGINX. Based on `python-socketio` documentation, this should be possible. I tried django + eventlet + gunicorn, but it seems like gunicorn a) [doesn't play nice with eventlet](https://github.com/benoitc/gunicorn/pull/2581) and b) only supports one worker. Gevent + Gunicorn doesn't have this bug, but still only supports one worker. Also, I'm not sure how actively maintained gevent is. So I'm not sure how scalable either Gunicorn + eventlet or Gunicorn + geventlet is as a WSGI server. So I'm not sure if Gunicorn is my best bet, or if it's too limited.

For building your API, I recommend using the Flask library. It is very beginner-friendly, and you will be able to build a simple API in a matter of minutes! Keep in mind that, for a more serious project, you should definitely use something like gunicorn to run you API as a production server.

Interesting looks like it might actually be a python bug. Somehow just changing from sys.exit(0) -> os._exit(0) apparently fixes it.

The cool thing is that you can easily migrate your WSGI- application such as Flask, Django, or Gunicorn to AWS.

Yeah, that's kind of the impression I was getting. I stumbled across a github issue for gunicorn along these lines.

In addition [Hypercorn](https://github.com/pgjones/hypercorn) (a ASGI and WSGI) also does not use gunicorn, having migrated many years ago.

You might find some recommendations to use hypercorn rather than uvicorn, I tried that initially but I couldn't resolve an issue with socket permission, I raised it as a bug in their GitHub repo.

for those wishing to use http3 with a Python web framework, the ASGI hypercorn[1] currently supports it.

made a Django example last week with a sample client based on the examples from aioquic[2]: https://github.com/djstein/django-http3-example

this example also includes the first pass at async Django REST Framework using adrift[3] based on these GitHub issues:

- https://github.com/encode/django-rest-framework/pull/8617

- https://github.com/encode/django-rest-framework/issues/8496

what about hyopercorn ? looks like it supports http3

By using Hypercorn like so:
