What you can monitor
The Lighthouse signals your team already knows, kept in context
Start with the summary, then open the result that needs attention. You do not need to read a raw Lighthouse report to understand where the change happened.
Loading and stability metrics
Follow LCP, CLS, FCP, and TBT with their measurement history.
Mobile and desktop baselines
Keep both strategies visible without treating a desktop score as a substitute for mobile.
Diagnostics and opportunities
Open the detailed audit to find the checks and recommendations behind a weak result.
A simple monitoring loop
From a URL to an explainable regression
Add the pages that matter
Group pages by project and monitor the home page, landing pages, checkout, or any public URL that affects your users.
Choose a testing rhythm
Enable mobile, desktop, or both, then select an available schedule that matches how often the site changes.
Review changes with context
Use history and release markers to narrow down when a regression appeared, then open the detailed audit.
