Gradio

Python library that lets you create web interfaces for machine learning models in minutes.

Overview

Gradio is a Python library that lets you create web interfaces for machine learning models in minutes. With a simple Python API and no JavaScript or CSS required, you can build interactive demos and deploy them instantly to Hugging Face Spaces or share them locally.

The framework includes 40+ pre-built components for handling images, audio, video, 3D models, dataframes, and more. It's designed for rapid prototyping—from initial demos to production-ready applications—with automatic scaling and permanent hosting options available.
