Google Lighthouse
An open-source automated auditing tool from Google that measures web page performance, accessibility, SEO, and best practices.
Lighthouse is the engine behind Google PageSpeed Insights and the basis for AuditJet's synthetic monitoring. It runs in Chrome (or headlessly), simulates a mid-range Android device with 4G throttling, and produces scored reports across Performance, Accessibility, SEO, and Best Practices categories. The performance score is a weighted composite of FCP, Speed Index, LCP, TBT, and CLS.
