Website and Android app tracking usually breaks quietly: a release changes the checkout, the purchase event still fires, but value or currency no longer arrives. Teams find out weeks later from a ROAS drop or a finance mismatch. How it works - Record a key journey once, such as product → cart →...

As answered by people managing SpeedCurve and AnalyticsProof.
AnalyticsProof's answer:
User journey tests are recorded once in a browser that runs on our servers, then replayed every day. Each step shows what the page pushed to the dataLayer next to what was sent to GA4 (and other tools), plus a cookie-banner check of what tools send before consent and after rejection. An MCP server lets AI assistants read results and set up checks.
AnalyticsProof's answer:
It checks the journeys that make money, such as cart and checkout, step by step, and says exactly which event or parameter stopped arriving after a release. Nothing is installed on the site. The same check runs on Android and smart-TV apps, which most tag-audit tools don't cover. Pricing starts with a free plan instead of an enterprise contract.
AnalyticsProof's answer:
Analytics leads, Head of Digital and e-commerce managers at companies that release often, and analytics/PPC agencies that look after tracking on many client websites.
AnalyticsProof's answer:
Built by Václav Ráš, a web analytics consultant who kept finding the same problem with clients: a release quietly breaks tracking and nobody notices for weeks. AnalyticsProof automates the check he used to do by hand in DevTools after every release.
