Marketing Tag Radar - GA4/GTM Debugger

About

Marketing Tag Radar is a Chrome extension for teams that need to review browser-visible marketing measurement implementation quickly.

Watch measurement fire in real time in the Chrome side panel as you browse. Unlike debuggers that show GA4 alone, it streams GA4, ad tags, Adobe Analytics, dataLayer pushes, and unknown beacons into one live feed — annotating each hit with a quality score, the issues it found, and the user action (click / scroll) that preceded it. Diagnostics run locally in the browser. The extension does not automatically send captured diagnostic data to the developer's servers or third-party servers.

Key capabilities:

- Live measurement feed: GA4, ads, Adobe, dataLayer, and unknown beacons in firing order, with per-tool filters and inline quality scores and issues
- Click-to-fire attribution: see which action (click / scroll / keypress) preceded each measurement hit
- Variable drill-down: expand dataLayer and JavaScript global variables level by level, like the Chrome console
- Deep GA4 diagnostics: events, IDs, collection routes, session quality, conversion quality, duplicate firing, and ecommerce/CV
- Cross-tool review: tag management, ad conversions, Adobe, consent signals, cookie attributes, unknown traffic, and technology candidates with supporting evidence
- Implementation score, firing timeline, prioritized action queue, and expected-vs-observed comparisons
- Export audit reports as JSON, Markdown, CSV, or a client-ready HTML report

This extension does not claim to prove every admin setting or server-side send. It helps teams quickly understand the marketing-measurement signals that are visible from the browser: network requests, HTML, cookies, dataLayer, JavaScript variables, and captured tag activity.
