17 Reasons Why Gradio Is not Just One other UI Library

“Oh, Gradio? That is a Python library for constructing UIs, right?”

We hear this lots, and while Gradio does allow you to create interactive UIs with minimal Python code, calling Gradio a “UI library” misses the larger picture! Gradio is more than a UI library—it is a framework for interacting with machine learning models through each UIs and APIs, providing strong guarantees around performance, security, and responsiveness.

In this text, we’ll introduce features which might be unique to Gradio and explain how they’re essential for constructing powerful AI applications. We’ll share links to Gradio’s official documentation and release notes, so you’ll be able to explore further for those who’re curious.

1. Universal API Access

All Gradio apps are also APIs! If you construct a Gradio app, you can too use Gradio’s robust client libraries for programmatic access to those Gradio applications. We provide:

• Official SDKs in Python (gradio_client) and JavaScript (@gradio/client), plus support for cURL API access
• Automatic generation of REST API endpoints for every event defined in your Gradio app
• Robotically-generated API documentation, accessible through the “View API” link
