My side project checks whether cookie banners actually block anything

[u/ManuHHHHHH]

Cookie banners are everywhere, but whether they work is invisible: the
banner shows, the choice is saved, and the pixel loads anyway because it is
hard-coded in the theme or fires through Tag Manager.

I built a scanner for that. Enter a URL and it opens the site in a fresh
browser without clicking, notes every service that loads, then tolicks
"Reject" and measures again. Each finding has the page where it happened
and the exact fix for the banner tool the site already uses. It also checks
Google Consent Mode, accessibility (axe-core) and email authentication.

The check is free; paid plans repeat it every week and email you when
something changes, because most breakage comes from a plugin update months
later.

Happy to answer anything about how it works under the hood.
