TagHound

TagHound Analytics/GTM/Pixel Debugger helps validate your analytics tools implementation as well as ad network pixels and Google Tag Manager dataLayer events - all in one tool. It works all the time for all the supported networks at once. In total, TagHound supports 22 analytics and ad platforms, including Google Analytics 4 (and older versions) & Google Tag Manager (events and dataLayer viewer), to give you a holistic tracking and pixel analysis experience.

Just navigate to any page, open your DevTools panel (F12), or click the extension icon (less information) and it will show you all your pixels and events, with a never-seen-before error validation (over 1200 validation rules). Just click the event to see all the data in a clear format, grouped by attributes. TagHound allows you to group events by type, performance and attributes. You can RECORD your debugging activity while navigating through any website and even export the results.
