What teams say about Tag Insight
After 10 years of tracking implementations, Tag Insight is the first tool that actually solves our documentation headaches.
Nicolas JardillerCEO, KixellTag Insight changed my freelance analytics practice. I deliver better audits in half the time, and the partnership program turns my implementations into recurring revenue.
Rémi VillepeletFounder, NaashWhat used to take days now takes hours, and the quality monitoring ensures we catch issues before they impact our clients.
Romain TrublardFounder, TrackAnalyse.comFrequently asked questions
Which tags can this checker detect?
Google Tag Manager, GA4, Google Ads, Meta Pixel, TikTok, LinkedIn Insight, Microsoft UET and Clarity, Hotjar, Matomo, Piano Analytics, Segment, Amplitude and more, plus the consent management platform running the banner.
Does it see everything my site loads?
The page is rendered in a real browser and we capture the network requests it makes on load, without interacting with the consent banner. What fires only after consent, on other pages or on user actions needs the full Tag Insight audit.
Is this tool really free?
Yes. It is free to use, no account required. We only read the public page you submit; your report stays available at its private link for 90 days.
