In Solara you can dynamically put together the UI like in react, in pynecone you need to use their primitives to make lists and conditional rendering. Also, state management is not tied to solara, but could use dataclasses or pydantic, wrapped in a reactive variable.

I think what sets Solara apart from the rest is that we use a 10 year proven paradigm, React, but on the Python side, although with a more Pythonic API. For instance making reusable components in Python is a real benefit. Pynecone uses ReactJS in the front end, but on the Python side it’s their own API.

I do like pynecone, their API is pretty. I do wonder with many of these frameworks. Does the paradigm works for more complex apps, or does it end in complexity hell once you go past the hello world examples. At least React has proven itself.
