Show HN: ConsentScope – detect cookies loaded before user consent
consentscope.proSo I recently ran a small experiment.
I tested 20 websites (SaaS, e-commerce, agencies, blogs) to check something simple:
Do they actually wait for user consent before loading analytics?
14 out of 20 loaded Google Analytics or other tracking scripts before the user clicked “Accept”.
In most cases:the cookie banner was visible, no interaction had happened yet but GA/GTM requests were already firing. You don’t really notice this unless you’re watching the Network tab closely.
So I built a small tool to monitor:
cookies being set
localStorage/sessionStorage usage
tracking-related network requests
the exact timestamp of the consent click
Originally it was just a script for internal audits. It grew into a Chrome extension called ConsentScope.
What it does:
-compares before vs after consent
-classifies cookies (necessary / analytics / marketing)
-shows a simple timeline of events
-optionally exports a report
It doesn’t auto-click banners. It doesn’t interpret the law. It just shows what technically happens.
I’m curious if others have checked this on their own sites. Feel free to ask anything technical — happy to share details.
