What problem does it solve?

This tooling guide targets frontend performance by systematically improving Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) with prioritized fixes and verification to meet performance budgets.

Core Features & Use Cases

• LCP optimization: image handling, preload strategy, and critical CSS techniques to reduce load times.
• INP optimization: debounce interactions, use Web Workers, and code-splitting to minimize input delay.
• CLS optimization: reserve space, apply aspect-ratio, and avoid layout shifts during render.
• Verification: supports Lighthouse and Web Vitals monitoring to verify improvements.

Quick Start

Run the Core Web Vitals Tuner against your project to apply prioritized fixes for LCP, INP, and CLS and verify performance.
