Notes

Deployment is just moving your locally working app somewhere that can run it continuously and expose it through a public URL. For a small Streamlit or Python web app, you do not need to rent a server, configure Kubernetes, or buy a domain. A free hosting platform can clone your repo, install dependencies, run your start command, and give you an HTTPS URL.
