Lighthouse Scout is a Chrome extension designed to automate site-wide performance audits using the PageSpeed Insights API. This tool allows users to analyze up to 100 pages at a time by simply entering a URL, with the option to extend the analysis to 1,000 pages. By leveraging available sitemaps or performing intelligent crawling, it identifies performance issues across an entire website, making it easier for users to enhance their site's speed and efficiency.

The extension provides detailed metrics on key performance indicators such as First Contentful Paint, Largest Contentful Paint, and others, offering insights into performance, accessibility, best practices, and SEO. With direct links to PageSpeed Insights reports, users can quickly access in-depth analysis for any page. A free Google PageSpeed API key is required for operation, ensuring that data is fetched accurately while maintaining user privacy.
