Lab Data

Last updated: 2026-03-294 min read

This guide covers Lab Data. How PageReflect runs Lighthouse in our cloud and why synthetic “lab” metrics are useful—and limited.

Each audit kicks off a headless Lighthouse pass (mobile configuration, performance category) on our servers. That produces repeatable lab metrics—useful for comparing runs and prioritizing fixes. If Lighthouse times out or is blocked, the pipeline continues and your report will note that lab data was partial or unavailable.

Sections below are outlines—we will deepen them over time. For live output, run an audit from your dashboard or try preview.
