PageSpeed vs Lighthouse §

Differences §

• PageSpeed Insights measures the performance metric only, whereas Lighthouse audits other aspects of a website, as well (SEO, accessibility, progressive web app, etc.)
• Google PageSpeed uses a “combo” of lab and real-world data, whereas Lighthouse uses lab data only (under consistent conditions) to build its report

Lighthouse is now incorporated into PageSpeed Insights. It is PageSpeed’s integrated analysis engine.
