What is it?

NiceGUI lets you build web user interfaces entirely in Python. You declare elements such as buttons, inputs, tables, charts, Markdown blocks and 3D scenes, and the framework renders them in the browser and forwards user events back to your Python functions.

It suits micro web apps, dashboards, robotics and smart home control panels, and interactive tuning of machine learning or hardware parameters. The project runs as a local web server or in native mode inside a desktop window, and it also works in Jupyter notebooks. Code changes trigger an automatic page reload during development.

The backend is built on FastAPI with a Vue and Quasar frontend, and communicates over a WebSocket connection. It is distributed on PyPI, conda-forge and Docker Hub.
