First-party sessions vs aggregated public data
Auditzy™ monitors captured sessions and page views from visitors on your site. PSI’s CrUX section summarizes eligible Chrome-user data without exposing your individual first-party visits.
First-Party RUM vs Lighthouse and Public CrUX
Auditzy™ monitors real-user experiences on your site for captured sessions and page views, with context such as device, network speed, device memory (RAM), operating system, browser, location, page, and configured journey. PageSpeed Insights reports a Lighthouse lab test and aggregated Chrome UX Report data when the tested URL or origin is eligible.
Short Answer
PageSpeed Insights combines one controlled Lighthouse audit with available CrUX data aggregated from eligible Chrome users over a rolling reporting window. It does not expose your individual first-party sessions or page views. Auditzy™ captures real-user experience data directly from your site, reveals variation across user and page segments, and connects website-speed differences with configured conversion funnels.
