Bring clarity to preview mode with Stape GTM Helper

A free Chrome Extension built for agencies and Google Tag Manager experts that simplifies the GTM preview mode into a clear, structured view of tags, requests, and consent data.

Made by people who debug in GTM every day

We know, GTM’s native preview mode can get messy and hard to navigate - especially in large containers with many tags. Our extension clears up that complexity and speeds up your debugging.

Everything you need for a cleaner GTM preview

• Entities Filter. Focus only on the tags/entities you’re testing.
• JSON Formatter. Makes incoming/outgoing JSON requests readable.
• Request URL Formatter. Displays URL query parameters as structured tables or JSON.
• Tag Type Coloring. Adds color and platform logos for Meta, GA4, Google Ads, Microsoft, etc.
• Tag Status Coloring. Instantly spot failed or 4xx/5xx requests.
• Consent Status in sGTM. Shows consent state (granted/denied) directly in the preview of your server GTM container.
