What is NiceGUI?

NiceGUI is a user-friendly, Python-based UI framework that allows you to create web-based interfaces that run directly in your browser. Whether you’re building buttons, notifications, or complex layouts, NiceGUI makes it easy to get started and customize your project.

Here are just a few things you can accomplish with NiceGUI:

Create interactive buttons and notifications.
Build modern, responsive web applications.
Seamlessly integrate Python’s power into your front-end.

How to Get Started

Installing NiceGUI is straightforward. Run the following command to add it to your project:

python3 -m pip install nicegui

A Quick Example

Let’s look at a simple example to see how NiceGUI works. With just a few lines of code, you can create a basic UI:

from nicegui import ui

# Add a label to the interface
ui.label('Hello, NiceGUI!')# Create a button with a click event
ui.button('Click Me!', on_click=lambda: ui.notify('Button was pressed'))# Run the application
ui.run()

Save this as main.py and start the project by running:

python3 main.py

When you execute this, your default web browser will open, and voilà — you’ve got a functioning UI! From here, you can expand your project with additional features and components.

Why NiceGUI?

NiceGUI stands out because it brings the simplicity of Python to front-end development. You don’t need to touch HTML, CSS, or JavaScript to create modern and responsive UIs. It’s perfect for developers who want to focus on functionality without being bogged down by traditional web development tools.
