- We mostly use notebooks as scratchpads or alpha prototypes.

- Papermill is a great tool when setting up a scheduled notebook and then shipping the output to S3: https://papermill.readthedocs.io/en/latest/

- When turning notebooks into more user-facing prototypes, I've found Streamlit is excellent and easy-to-use. Some of these prototypes have stuck around as Streamlit apps when there's 1-3 users who need to use them regularly.

- Moving to full-blown apps is much tougher and time-consuming.
