User reviews

One of my standard Chrome extensions for testing new GTM containers or executing and integrating additional JavaScript. The additional consent banner reset function saves time and many annoying clicks.

Thank you for that tool. It is a very helpful free alternative to the GTM Injector.

Super helpful tool. And the developer always tries to improve it. Clear recommendation for web analysts who have to do many technical implementations (especially with the Google Tag Manager).
