What it is
NiceGUI lets you write a web user interface in Python. You describe buttons, dialogs, charts, and other elements in Python code, and the framework shows them in a web browser. It is aimed at small web apps, dashboards, robotics projects, and smart home tools.
- Build a small dashboard that shows live data with plots, tables, or 3D scenes
- Create a control panel with sliders, switches, and buttons for a machine or device
- Add a simple file upload page or form to a Python script
- Run a UI inside a Jupyter Notebook for interactive exploration
Great for
- Python developers who want a quick web interface for a script or tool
- Hobbyists building dashboards or controls for hardware or smart home projects
- Engineers tuning machine learning or motor controller settings through a browser UI
- People who want to run a UI in a desktop window instead of a browser tab
Not ideal for
- Large public websites that need heavy custom front-end work, since the README centers on Python-driven UIs rather than custom JavaScript pages
- Teams that need to write their UI in JavaScript or TypeScript, since all UI logic is written in Python
- Projects needing a verified production security or scaling track record, which the README does not address
How to get it
- 1
Install with a package manager
You'll need: Python 3
Install NiceGUI from PyPI
python3 -m pip install nicegui - 2
Run it
- Create a file named main.py.
- Add `from nicegui import ui`, then a label and a button, and end with `ui.run()`.
- Run `python3 main.py` in a terminal.
- Open http://localhost:8080/ in your browser.
- 3
Get the most out of it
- Use the live demos in the official documentation at nicegui.io to learn each element
- Point AI coding assistants at nicegui/llms.md, which the README says ships with the package
- Browse the examples folder in the repository for larger sample projects
- Run the docker image `docker run -p 8080:8080 zauberzeug/nicegui` to try the website without installing Python packages
Downloads
Strengths
- Simple example: a few lines of Python produce a working page, as shown in the README
- Includes many ready-made elements such as charts, tables, Markdown, and file upload
- Reloads the page automatically when code changes, which speeds up iteration
Trade-offs
- The README says less about production deployment, security, and scaling than about getting started
- Built on Vue and Quasar behind the scenes, so deep customization may require knowledge of those tools
- Documentation and examples are hosted on an external site, so the README alone gives limited detail
