Neat idea and elegant execution. The vibe I'm getting from the README is that I'd want to reach for this as a Python dev (over Streamlit or Gradio) if I already have a FastAPI app and want a simple dashboard in front of it. Is that right or am I misreading?

That's probably not a very good strap line - FastUI let's you declare new views and parts of views without writing any React, but the frontend if still just React, albeit optionally pre-built.
