NiceGUI

We like Streamlit but find it does to much magic when it comes to state handling. In search for an alernative nice library to write simple graphical user interfaces in Python we discovered justpy. While too "low-level-html" for our daily usage it provides a great basis for "NiceGUI".

Purpose

NiceGUI is intended to be used for small scripts and single-page user interfaces with a very limited user base. Like smart home solutions, micro web apps or robotics projects. It's also helpful for development, when tweaking/configuring a machine learning training or tuning motor controllers.

Features

• browser-based Graphical User Interface
• shared state between multiple browser windows
• implicit reload on code change
• clean set of GUI elements (label, button, checkbox, switch, slider, input, ...)
• simple grouping with rows, columns and cards
• genral-purpose html and markdown elements
• built-in timer to refresh data in intervals (even every 10 ms)
• straight-forward data bindings to write even less code

Install

python3 -m pip install nicegui

Usage

Write your nice GUI in a file main.py:

from nicegui import ui

ui.label('Hello NiceGUI!')
ui.button('BUTTON', on_click=lambda: print('button was pressed'))

Launch it with:

python3 main.py

The GUI is now avaliable thorugh http://localhost/ in your browser. Note: The script will automatically reload the page if you modify the code.

API

The API reference is hosted at https://nicegui.io and is implemented with NiceGUI itself. You should also have a look at examples.py for an extensive demonstration of what you can do with NiceGUI.
