Gradio

What Gradio sends out of your computer by default, when, to whom, and the switch that stops it, version by version, with how we know.

The answer

By its source at 6.2.0, not run: Gradio sends an event to huggingface.co when an app is created, when it launches and on errors (the interface's components, inputs, outputs and events, the Gradio version, whether sign-in is used, and error messages), and checks api.gradio.app for a newer version each time an app builds its interface; GRADIO_ANALYTICS_ENABLED=False, set before the program starts, stops both (it also sets HF_HUB_DISABLE_TELEMETRY for that process), and you are then no longer warned that a newer Gradio exists.

When
The code at 6.2.0 sends an event when an app is created, when it launches, and on errors, each in a background thread, through huggingface_hub's telemetry sender: a request to huggingface.co whose path names the event; not run.
Where
vendor telemetry collector · huggingface.co
What it sends
the interface's components, inputs, outputs and events, the Gradio version, and whether sign-in is used, in the request's user agent (usage); error messages, when an error is reported (diagnostics)

Many model demos and Hugging Face Spaces run on Gradio, and a copy you run yourself carries the same default. — github.com · analytics.py, read 2026-10-10
Gradio hands these events to an internal sender in huggingface_hub, which at 1.27.0 does not read HF_HUB_DISABLE_TELEMETRY; Gradio's own switch is the one that stops them. — github.com · _telemetry.py, read 2026-10-10

The switch

GRADIO_ANALYTICS_ENABLED=False

Accepted values
False
What it is
environment variable
Where it must be set
in the environment of the program, before it starts (see Turn them off) · turn them off
Other spellings
analytics_enabled=False when the app builds its interface
Also turns off
its version check; Hugging Face Hub telemetry for that process (it sets HF_HUB_DISABLE_TELEMETRY)
What turning it off costs
you are no longer warned that a newer Gradio exists
Proof
found in code and documented; not tested by us
