What problem does it solve?
Diagnoses and fixes UI performance across loading speed, rendering, animations, images, and bundle size. Use when the user mentions slow, laggy, janky, performance, bundle size, load time, or wants a faster, smoother experience.
Core Features & Use Cases
- Assess Performance Issues: Measure Core Web Vitals (LCP, FID/INP, CLS), load time, bundle size, runtime performance, and network metrics; identify bottlenecks across initial load, interactions, and animations.
- Optimization Strategy: Provide a systematic plan for loading performance, rendering performance, animation performance, and network optimization.
- Core Web Vitals Optimization / Verification: Target improvements to LCP, FID/INP, CLS, TTI, FCP, and perform before/after verification.
- Performance Monitoring: Suggest tools and metrics for ongoing monitoring and real-user performance data.
Quick Start
Run a performance audit of the current UI and implement the top recommended optimizations to achieve smoother interactions and faster load times.
