Gradio

What is Gradio?

Gradio is an open source Python package that gives your model or function a web interface without any JavaScript, CSS or frontend work. After pip install gradio, a few lines of Python wrap a function in an Interface, or you can lay out a larger app with Blocks or a ChatInterface for chatbots. More than 40 components cover input and output for images, audio, video, 3D, dataframes, plots and more. Setting share=True prints a public link to the demo running on your computer, which expires after 72 hours, while permanent hosting is available for free on Hugging Face Spaces. Gradio can load models and Spaces from the Hugging Face Hub, offers a Python client, a JavaScript client and cURL access to query an app programmatically, and can be mounted inside a FastAPI app. ML engineers, researchers and developers use it to prototype, collect feedback and ship internal tools. The library is free to use.

Use cases

• Build a demo for a machine learning model
• Create a chatbot interface in Python
• Share a prototype with a public link
• Host a demo on Hugging Face Spaces
• Build dashboards from live data
• Query an ML app from Python or JavaScript

Who it's for

• ML engineers
• Researchers
• Data scientists
• Python developers

Why use Gradio

• You stay in Python, so a data scientist can ship a working interface without learning web development.
• One parameter produces a link you can send to a client or colleague, while the code keeps running on your own machine.
• Free hosting on Hugging Face Spaces gives demos a permanent address.
• Programmatic clients let other code call the same app, which is useful for pipelines and automation.
• A large set of ready components covers common ML input and output types.

How to get started with Gradio

1. Install the library with pip install gradio.
2. Write a Python function and wrap it in gr.Interface, or compose a layout with gr.Blocks.
3. Run the script to launch the app on your local machine.
4. Set share=True for a temporary public link, or deploy the app to Hugging Face Spaces for permanent hosting.
5. Call the app from Python, JavaScript or cURL using the generated API page.

Gradio limitations

• Public share links expire after 72 hours unless you set up your own Share Server
• A share link exposes your app publicly, so add authentication or avoid sensitive functions
• The first call to a model through Inference Endpoints can be slower while it loads

Gradio pricing

Gradio is open source, so you can use and self-host it for free.

Prices can change and may vary by country or exclude tax. Check the official pricing page.
