What is Gradio?
Open-source Python framework for demo UIs around ML models.
Who is Gradio best for?
Gradio is best for Python developers and machine learning researchers who want a model demo without writing frontend code.
Model demos from Python
A few lines wrap a Python function in a web interface, with no frontend skills needed.
Showing work in progress
One launch setting gives a public link to an app still running on your own machine, handy for clients or colleagues.
Chatbot and media prototypes
Ready-made chat, audio, video, image, 3D and dataframe components cover most AI demo inputs and outputs.
Tools for AI agents
An app can also run as an MCP server, so clients such as Claude Desktop or Cursor can call its functions as tools.
How much does Gradio cost?
Gradio is free and open source under the Apache 2.0 license, so the only cost is hosting: Hugging Face Spaces runs apps on free CPU hardware, and dedicated GPUs start at $0.40 an hour.

How long do Gradio share links last?
Gradio share links expire after 1 week. They pass traffic through Gradio's share servers to your own computer, so the app only works while that machine stays on. For a permanent address, host the app on Hugging Face Spaces or set up your own share server.
Can a Gradio app work as an MCP server?
Yes. Launching a Gradio app with mcp_server=True turns its functions into MCP tools that clients such as Claude Desktop, Cursor or Cline can call. Gradio builds each tool from the function's name, docstring and type hints.
