alt Hacker NewsStreamlit apps or similar are doing a great job at this where I'm at.
As simple to build and deploy as Excel, but with the right data types, the right UI, the right access and version control, the right programming language that LLMs understand, the right SW ecosystem and packages, etc.
Are they actually as simply to deploy as Excel? My guess would be that most streamlit apps never make it further than the computer they're written on.
