panel VS DearPyGui

panel – data exploration & web app framework for Python

https://panel.holoviz.org/ It's a web app framework for Python similar to what Dash does for plotly. It plays nicely with bokeh visuals and I think the front-end is built using bokeh css elements.

I'm following the Panel FastAPI example here: https://github.com/holoviz/panel/blob/main/examples/apps/fastApi/main.py

If you want to build Python dashboards, look at the solara (react-style lib, https://solara.dev/) and panel (https://panel.holoviz.org/).

panel

My suggestion is https://panel.holoviz.org/

Fully open sourced, makes it easy to make reactive apps with small changes, can even configured as a graphical REPL.

I am doing something like this in a [panel](https://panel.holoviz.org/) dashboard, which I am currently converting to nicegui. Maybe I can provide an example in some days.

Ill have to check it out and see how it compares to voilà and holoviz panel. What I like about Holoviz panel is you can create a data web app from code that resides in a notebook or create a completely standalone app from just plain py scripts, and it supports many different visualization backends. I have found it to be the more flexible and generalizable data web app framework among the others I have come across (like Voilà, Dash, Plotly, and Streamlit).

Like the previous three alternatives, Panel is an open-source Python library for creating interactive dashboard web apps. Panel is extremely flexible, allowing you to use any plotting library you like. Like Gradio but unlike Streamlit, you can use Panel in Jupyter notebooks. Panel dashboards can also be deployed as standalone web apps, but like Plotly Dash, you'll need to set up a server to deploy it yourself.

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

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

If it's just to align text in the centre or to the right of a box, you could use a button and, by using theming, hide the fact that it's a button. https://github.com/hoffstadt/DearPyGui/issues/1111

Personally, i like PyQt or PySide they have basically everything you need to make a proper app or even simple apps, but there is another DearPyGui this is basically python version of imgui the c++ library, it provides some good customization options and can be used for simple or complex projects too, their discord is also very helpful.

There are some examples in the showcase as well. https://github.com/hoffstadt/DearPyGui/wiki/Dear-PyGui-Showcase

I'm a big fan of DearPyGUI

Use a button and set width of the button equal to the width of the window. Using theming to set the button text alignment to center. A comparable solution, for aligning to the right, can be found here. https://github.com/hoffstadt/DearPyGui/issues/1111

I was using PyQt5/PySide which will give you a nice native look but I eventually shifted over to DearPyGui for most of my smaller utilities. Its just faster for me. You will get more options and freedom with PyQt/PySide though and can use QT Designer to design your interfaces pretty easily.
