Analyze web page performance using Web Vitals and network timing metrics.
Analyzes web page performance via Core Web Vitals (LCP, FID, CLS), network timings, JS tasks, layout shifts, and resource optimization. Audits with thresholds and recommendations.
Audits web page performance measuring Core Web Vitals (LCP, FID, CLS, FCP); identifies bottlenecks and recommends optimizations for speed, UX, and SEO.
Audits web page performance using Chrome DevTools MCP: measures Core Web Vitals (FCP, LCP, TBT, CLS, Speed Index), identifies render-blocking resources, network chains, layout shifts, caching issues, accessibility gaps. Invoke for load audits, Lighthouse scores, site speed optimization.
