Why is it not recommended to run a Django application using the manage.py file in production?

The manage.py file in Django is intended for development and debugging; it runs the built-in development server, which is not optimized for production.

Reasons not to use manage.py runserver in production:

• The built-in server is single-threaded and inefficient under high load.
• It lacks support for scaling and load balancing.
• It does not provide crash protection or advanced security features.
• It does not support advanced web server configurations (e.g., SSL, caching).

In production, it is common to use WSGI servers (like Gunicorn, uWSGI) behind a reverse proxy (Nginx, Apache), which provides stability, performance, and security.
