Gradio is an open-source dev tools project by gradio-app (gradio-app/gradio on GitHub). It has 43,671 GitHub stars and 3,616 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 2 October 2026.
Any Python function — a model call, a transform, a pipeline — becomes your app logic.
Declare inputs and outputs; Gradio builds the UI around them.
One call serves a local web UI with API docs included.
Get a public link or deploy permanently to Hugging Face Spaces.
From Python function to interactive web app in under ten lines of code.
Chatbots, image editors, audio recorders, 3D viewers, and dataframes out of the box.
Stream tokens, audio, and video for responsive real-time demos.
Every demo ships an OpenAPI endpoint — script it like any web service.
One click deploys your demo free on Hugging Face Spaces.
Theme builder and custom CSS for demos that match your brand.
Pip-install Gradio into your environment.
pip install gradioInterface, Blocks, or ChatInterface — pick the abstraction that fits.

demo.launch(share=True)It is an open-source project at gradio-app/gradio with 3,245 forks. Check the repo's contributors and recent commits to see how active maintenance is.
Yes — Apache-2.0, including the hosted sharing links.
Gradio is purpose-built for ML demos (media components, streaming); Streamlit is a general data-app framework.
Yes — run locally on your hardware, or deploy to Spaces with GPU upgrades.
Local launches work on your LAN; public share links need internet.
