description Lighthouse Overview

Lighthouse is an open-source, automated tool for improving the quality of web pages. Built directly into the Chrome DevTools, it audits performance, accessibility, progressive web apps, SEO, and more. It is the engine behind Google PageSpeed Insights, but running it locally in your browser gives you more control and immediate feedback during development. It is an essential tool for developers who want to build high-quality, performant, and accessible websites from the ground up.

It provides clear, actionable advice for every audit it performs.
