Custom GTM and GA4 Loader

Custom Loader is a free power-up that loads GTM and GA4 scripts through your own domain or a same-origin path, making them harder for ad blockers or tracking restrictions to detect. This helps you capture more complete analytics and advertising data.

Custom Loader is available to all Stape users. You can find it in the Power-Ups tab in your Stape account.

Custom Loader changes the standard loading path for gtm.js and gtag.js and loads them through your domain or the same-origin path you choose. This makes GTM and GA4 scripts more resistant to ad blockers because they stop using the default paths that blockers target. 

• Recover more tracking requests from ad blockers. Custom Loader changes the paths used by gtm.js and gtag.js, so blocking tools have fewer default Google script patterns to target.
• Support more stable first-party cookies. Custom Loader works with a custom domain or same-origin path. This helps your tracking setup use first-party cookies and reduces data loss from browser tracking restrictions.
• Measure how many requests Custom Loader recovers. Stape Analytics turns on automatically when you enable Custom Loader, so you can see the recovered requests and understand how much data it brings back. 

Use Custom Loader to keep GTM and GA4 scripts running, send more requests to your sGTM container, and improve reporting and campaign optimization.
