HTTP Alternate / Development Server
What is port 8000?
Port 8000 is commonly used for development web servers. Django's built-in dev server runs here by default (python manage.py runserver), as does Python's http.server module, Jekyll, and many other development tools. It is not typically exposed directly in production — place nginx or Apache in front as a reverse proxy instead.
