THE PROBLEM

GA4 shows you yesterday.
Pulsr tells you right now.

A developer renames a dataLayer event. A CMP update blocks GA4. A checkout plugin fires purchase twice — or not at all. The ad budget keeps running. Nobody notices until the monthly report. Pulsr catches it in under an hour.

⚡

GTM events checked every hour. Alerts fire in minutes, not days.

🎯

Signal over noise

Only the events that matter. Configurable thresholds per client.

🔌

Any GTM container

One Custom HTML tag. Works with any site, any stack, any CMP.
