CheckGTM Helper

See any site's tracking setup in one click: GTM containers, server-side GTM, GA4, Consent Mode and ad pixels.

Open any website, click CheckGTM Helper, and see the tracking running on that page. The extension only reads the page in front of you, and only when you click it. It doesn't collect or send any data to any server. What you'll see: • Google Tag Manager containers, how many there are, and whether one is loaded twice • Whether the site uses server-side GTM: a custom gtm.js domain, a transport_url, or GA4 hits sent to a first-party server • GA4, Google Ads and Floodlight IDs • Consent Mode state: defaults, after the visitor's choice, and right now • The ad pixels and analytics tools running on the page, with their IDs and a warning when a pixel loads twice • The platform the site is built on, such as Shopify or Salla stores • The latest dataLayer events • Color-coded quick notes: red for problems, yellow for warnings, green for what's working Need more than what the page exposes? Run a free full GTM container audit on checkgtm.online. It reviews your tags, triggers, variables and consent setup, and tells you what to fix. Available in Arabic and English, with dark mode.
