kivy VS nicegui

We will create this complete Python registration form using Kivy. We get started by installing Kivy, a powerful Python framework for building interactive applications.

For reference, YouTube runs on Python[1,2,3]:

> 1. Python and Django: YouTube’s backend is predominantly written in Python, offering a balance of performance and readability.

> 2. Google Cloud Platform...

> 3. Java and C++: YouTube also utilizes Java and C++ for specific backend services, as they provide better performance for certain tasks.

A long time ago, I looked into these Python frameworks:

I have a multi-threaded app using Kivy for the GUI and sometimes need to update the GUI from a background thread. This app is a few years old and I recently updated to Kivy 2.2 and am now getting an exception with the message "Cannot create graphics instruction outside the main Kivy thread" -- which is related to this change in Kivy 2.1: https://github.com/kivy/kivy/pull/7270

I suggest you use kivy which is suitable for the desktop but also has the advantage of being one of few options for creating Python based native(ish) mobile apps (for IoS and Android app stores).

I think the best one right now for python is "beeware": https://beeware.org/

You also have Kivy which is prety good: https://kivy.org/

Anyone has some experience with Kivy [1]? It seems that it checks off some of my requirements, like cross-platform, supporting touch interfaces, ease of development, allows complex/fancy UIs as well, etc.

There are hot reload tools like kivy.tools.kviewer and KivyMD HotReload and I think others... but maybe they used something else, hard to tell

I was looking at this space and nicegui seemed like the best ootb experience.

https://nicegui.io/

Dash is similar in spirit, as a "build web UIs with Python" framework. Dash seems more similar to nicegui (https://nicegui.io) architecturally than to Hyperdiv. Like nicegui, it builds a static dom that is then mutated via callbacks or data bindings.

By contrast, Hyperdiv lays out UI declaratively based on state, and when state changes, the app re-runs, generating an updated UI. Streamlit and Hyperdiv seem to work similarly, though I'm not sure how Streamlit handles state and state-based layout.

For native GUI, DearPyGui[0] as modern as you can.

For browser web-based GUI, you can use nicegui[1]

I want to bring to attention a set of frameworks that make webdevelopment using Python simple and fun. The popular opinion maybe that webpages developed with Python maybe slow. But this is not the case. Do checkout https://github.com/ofjustpy/ofjustpy/, https://github.com/zauberzeug/nicegui/ and https://github.com/justpy-org/justpy . All these frameworks are build on top of Starlette and make web development really easy. If you want simple and ready to use the nicegui is the choice. If you want fast, scalable, and more control then give ofjustpy a try.

Yes, NiceGUI aims for a very gentle learning curve. Coming from Streamlit I suspect your main adaptation will be that in NiceGUI you need to write valid Python code. Streamlit constantly reevaluates your script which feels nice and easy but creates lots of problems down the road. See https://github.com/zauberzeug/nicegui/discussions/21.

Auth is a big limitation. It's not a built-in component, they have [an example](https://github.com/zauberzeug/nicegui/blob/main/examples/aut...) using the FastAPI layer for auth, but I haven't had time the time to try implementing it. It's definitely not something you get out of the box with NiceGUI.

For scaling, I am viewing it mostly as an internal tool builder. I wouldn't recommend it for external applications. So as far as scaling an internal app I think it works fine. [Their website](https://nicegui.io) is built with NiceGUI, and it works fine, but you can feel the lag occasionally on some of their larger demo pages.

Well, I was at PyCon Ireland last weekend and I missed the NiceGUI talk. I hear postive things about it and anything shiney and anything frontend-related always catches my attention (although I admit talking to a friend when I missed this talk was just as fun, and it was worth it).
