  Consent Mode Monitor: Consent Mode Checker and GTM Consent Audit

  Consent Mode Monitor: Free GTM scanner

• Apr 17, 2026
  description

  Verify Consent Mode V2 directly in your browser, in seconds.
  
  Consent Mode Monitor is a Consent Mode V2 monitor and GTM consent management checker that helps you spot broken consent setups fast.
  
  Consent Mode Monitor analyses your GTM configuration and highlights tags with missing or incorrect consent. It parses the site, does not require GTM permissions, and does not change your GTM setup.
  
  Using the Chrome extension means you can check sites faster, directly on the page, and you are less likely to be blocked by Cloudflare or similar WAF systems. You can also get a full audit report.
  
  
  KEY FEATURES:
  
  1. Consent Mode V2 monitor: validate consent behaviour while browsing, ideal for quick compliance checks.
  
  2. GTM consent audit: identify tags with missing or incorrect consent so you know what is actually broken.
  
  3. No GTM access required: works by parsing the site’s published setup, without changing anything in your container.

  Run a 1-click scan of Google Consent Mode on any website that uses GTM and share the result via URL report.
