What it does
Lab and field data together
Scheduled lab runs beside real-user metrics, with 12 months of history so trends and regressions are visible.
Competitor benchmarking
Track the sites you compete with for the same searches and see exactly where you are behind.
AI consultant and alerts
Code-level recommendations for each finding, and anomaly alerts to Slack or email the moment a metric slips.
Who it is for
Engineering teams and revenue-critical sites that need performance to hold for SEO rankings and user retention, and want a number to point at when it does not.
Built and run by Zactonz
