How these tools work
All of them run in your browser. The GTM tools fetch the public container from www.googletagmanager.com, the same file every visitor to the site downloads, and parse it in the tab. The calculator, UTM builder and name checker make no network requests at all. Nothing you type is sent to Fireshift.
They are built by the team behind the Fireshift scan, which reads what a site sends to Google Ads, GA4 and Meta from the outside and flags conversions that are not funnel progress. The tools are the parts of that work you can do by hand.
