I realise that this is probably just an example for HN so this isn't criticism of your comment! But in case anyone reading doesn't know already, `runserver` is not appropriate for running in production.

It doesn't have any security hardening, is single threaded and blocking, will reload code as it changes, and is generally very slow.

It's generally best to use something like gunicorn, uwsgi, uvicorn, etc, and also to then host behind something like nginx which is designed to be exposed to potentially malicious users.
