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.

Hourly monitoring

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.
