No. Point it at any address that loads in a browser: staging, a preview deploy, production, or the competitor you keep bringing up.
Sixty-one rules. Contrast, hit areas, type scale, spacing steps, focus rings, motion that ignores the reduced-motion setting, and whatever you add yourself.
The scan needs to fetch the page, so it needs a connection. Everything after that runs on the handset, history included.
Nobody. The page never leaves your phone, and the only thing that goes home is a count of findings fixed with no address attached.
It removes the part of review that is arithmetic, so the meeting is about the idea instead of the contrast ratio on one button.
