In plain English

NiceGUI is a Python framework for building user interfaces that show up in a web browser. Instead of designing HTML pages or wiring up a separate JavaScript frontend, you write Python code that describes the buttons, labels, sliders, dialogs, charts, and so on, and NiceGUI takes care of rendering them in the browser and shuttling clicks and inputs back to your Python code. The tagline is "create web-based user interfaces with Python, the nice way." A minimal example from the README is just a few lines: import ui from nicegui, call ui.label and ui.button, then ui.run(), launch it with python3 main.py and the interface is reachable at http://localhost:8080/. It also reloads automatically when you change the code. You install it with pip install nicegui, and it is also available as a Docker image and on conda-forge. The framework is aimed at micro web apps, dashboards, robotics projects, smart home setups, and similar use cases, plus developer tools, for example, tweaking a machine learning algorithm or tuning motor controllers while watching live values. Beyond standard widgets, it can plot graphs and charts, render 3D scenes, accept input from virtual joysticks, annotate images, show tables and tree structures, embed audio and video, and refresh data on a timer as fast as every 10 ms. It runs in Jupyter Notebooks, supports data binding, shared and per-user pages, persistence, custom routes, global keyboard shortcuts, and theming. Under the hood, the README says NiceGUI is built on FastAPI, Starlette, and Uvicorn for the server side, with Vue and Quasar handling the browser side. The full README is longer than what was provided.

Copy-paste prompts

Prompt 1

Using NiceGUI, build a Python dashboard that shows a live-updating line chart of CPU usage refreshed every second.

Prompt 2

Create a NiceGUI web form with text inputs, a dropdown, and a submit button that calls a Python function and shows the result on the page.

Prompt 3

How do I add a 3D scene widget to a NiceGUI app? Show me a minimal working example.

Prompt 4

Build a NiceGUI app where each browser tab has its own independent state so two users do not see each other's data.

Prompt 5

Write a NiceGUI app with a virtual joystick widget that logs the X/Y position to the Python console in real time.
