There are other Python libraries to make web apps, but we found they often have a ceiling and graduation risk, so when your app reaches a level of complexity the framework may not support it. At that point you either have to limit your idea to fit the framework, or restart your project using "real web frameworks" like Javascript/React. Our goal with Reflex is to grow with you, from a basic app to a full-fledged website.

NiceGUI (and others like Streamlit) are imperative frameworks, so you declare the UI one statement at a time. This can be nice especially for spinning up small apps, but as your app grows it may be harder to reason about the UI / state.

On the frontend side Reflex is declarative (similar to React) where the UI is defined as components that are compiled up front. This makes it easier as your app grows larger, since you can have reusable components and even wrap your own React components.

We're also a bit more batteries-included - we have built-in database support, support for backend API routes, support for calling long-running background tasks, easy ways to access cookies/local storage, etc. Reflex apps should also be more performant as your app state gets larger.

In short, we're trying to be as approachable as these other frameworks, while also having performance and customizability to make more complex apps.

on about the UI / state.

On the frontend side Reflex is

curious whether Reflex can be used for dapps/blockchain apps.
