Eventloupe separates seen, failed, and unknown
A planned Chrome DevTools extension for inspecting GA4, Meta Pixel, GTM, and dataLayer events alongside their observed network responses.
- For
- Analytics implementers debugging browser-side tracking
- Worth noticing
- The sample distinguishes a confirmed HTTP 500 from an unobservable response, which remains “unknown,” not an inferred error.
Field notes
The walkthrough spans a sample product-page flow, from a GTM container load through view_item and add_to_cart events, consent status, and tags from multiple platforms. The documentation describes parallel capture from dataLayer or SDK activity and network traffic, followed by six evidence stages and rule-based diagnostic codes. The page says the same input returns the same result and that no AI decides validity; the extension itself is still presented as forthcoming.
