Synthetic journeys.
Scripted multi-step flows that behave like a real visitor. Chrome, Firefox, and Safari on desktop and mobile, running out of US, EU, and APAC regions to catch geo-specific breakage.
pillar 1Product
See every tag fire from real user sessions.
135 data points per event across 80+ ad and analytics vendors, captured from live traffic instead of scheduled crawls. When a tag breaks, you know inside two seconds, with the revenue already attached.

What the platform does, at a glance.
The product is four things, layered: scripted journeys that behave like users, validated checks on every run, incidents that open themselves, and alerts the right human actually sees.
Automated checks.
GA4 events, Meta Pixel, LinkedIn Insight, TikTok Pixel, and Core Web Vitals are validated on every run. You find out the minute a tag stops firing, not at the end of the month.
pillar 2Incidents, self-opened.
Failed checks open incidents automatically, with severity, affected components, and resolution notes tracked in one timeline across every site you monitor.
pillar 3Alerts that route.
Slack, email, Microsoft Teams, PagerDuty, and webhooks. Route by severity, site, or owner so the right person sees a purchase failure before the next campaign push.
pillar 4# how_it_works
From signup to first alert in under 15 minutes.
No engineering ticket. One script in the head, real-user data on the next pageview, alerts before the next campaign push.
1
Drop in one script.
A ~30 KB gzipped tag in <head>. Auto-detects GTM, GA4, Meta, TikTok, and 80+ other vendors. Runs independently of GTM, so a GTM outage will not blind you.
2
Watch real sessions.
Every real user visit is observed. Tag fires, HTTP status, latency, consent state, and revenue values stream into BigQuery for your team to query.
3
Hear about failures first.
Purchase tag missed? Slack ping inside two seconds with the cart value. Consent block? Email with the exact violation. Every miss ties back to the dollars at stake.
