Google Analytics Inspector

GA4 Inspector is a developer tool for debugging Google Analytics 4 implementations. It intercepts every GA4 network request in real time and displays it in a structured, readable format in Chrome's side panel — replacing the manual process of digging through DevTools network requests and decoding URL parameters by hand.

If you work with GA4 — whether you're a developer implementing tracking, an analyst verifying data quality, or a QA tester checking an e-commerce funnel — this extension shows you exactly what data is being sent to Google Analytics, flags what's wrong, and generates a report you can hand to a developer to fix.

GA4 Inspector automatically detects whether each event is being sent directly to Google Analytics (client-side) or routed through a server-side Google Tag Manager container (sGTM). Three tabs at the top of the panel let you filter between All, Client-Side, or sGTM events. Each event card is clearly tagged so you can verify both data pathways independently.

GA4 encodes product data as compressed pr strings (pr1, pr2, etc.) that are difficult to read in raw form. The extension decodes every item into a structured card showing item name, ID, price, quantity, brand, category, variant, and all custom dimensions and metrics. Custom dimensions are displayed in a clearly labelled section, and custom metrics are shown separately — so you can verify that product data is being structured correctly rather than serialised into a single string parameter.
