GTM Inspector
Peek inside any public Google Tag Manager container. Enter a website URL to auto-detect its GTM IDs, or paste a container ID directly — and see every tag, trigger and variable, including the internal infrastructure GTM hides in its own UI. Reads published containers only; nothing is stored.

This is the quick look. Want the full audit?
The GTM Inspector shows you what’s in a container. Tracking Auditor tells you whether it’s right — a scored audit across consent, GTM governance, GA4 event quality and conversion integrity, with a prioritised fix plan and a client-ready report. Your first audit is free.
