Designed for clarity
Useful signal, minimal footprint.
Every measurement is generated locally in this tab against the hostname already open in your browser.
Same-origin probes
The check requests a tiny local health object. It contacts no analytics, ad network or external API.
Honest boundaries
A green result confirms this endpoint at this moment—not the health of the entire internet.
Session-only data
Samples remain in page memory and disappear when the tab closes. Nothing is uploaded.
