About Gradio

Gradio is an open-source Python package for building demos and web applications for machine learning models, APIs, and other Python functions. It is maintained in a public repository and is documented with guides and examples for getting started.

You install it with pip and write a few lines of Python to define inputs, outputs, and a function. The gr.Interface class connects a function to input and output components, and demo.launch() opens the app in a browser or embeds it in a notebook. Built-in sharing features can create a link to share the demo. It runs in code editors, Jupyter notebooks, Google Colab, and other Python environments.

It suits Python developers, data scientists, and others working with models or data analysis who need a working web interface without JavaScript, CSS, or hosting setup. Python 3.10 or higher is required.
