I am definitely target audience for this.

I am often in need of building internal tools, dashboards - simple apps with simple UI that doesn't need to be unique, drive engagement, or whatever. It needs to get the job done and let me move on.

Streamlit is close but the peculiar approach they take (rerun the script) makes it unwieldly for more complex apps (say, a few related pages, a few dozen components each).

I've been looking for a way to just let me do "GUI app in Python" that get delivered over HTTP and rendered in browser, and Rio is exactly what I was hoping for.

Yeah, no chance Meta will rewrite FB frontend to use Rio. Also pretty sure that I won't be doing any fancy websites in it. But if I can skip dealing with React/Vue/HTMX/whatever on the frontend for some internal thingy.

I only tried doing some simple stuff but so far I really like what I see!
