Lighthouse
Lighthouse 是由 Google 开发的开源自动化 Web 质量审计工具，可集成于 Chrome 开发者工具、命令行或 Node.js 模块中使用。它能对网页的性能（Performance）、可访问性（Accessibility）、最佳实践（Best Practices）、搜索引擎优化（SEO）及渐进式 Web 应用（PWA）合规性进行全面检测，并生成评分报告与优化建议，帮助开发者提升网页质量。
Core Facts
Timeline (last 90 days)
The Kaury language's official website is itself written in Kaury, showcases six running sites, scores 100 in Lighthouse on desktop, 98 to 100 on most pages on mobile, and 93 on the homepage because it runs a 3D scene.
Mature accessibility tools such as Axe-core and Lighthouse work around the static-HTML limitation of not being able to detect JavaScript-rendered content by running in a real browser environment, but this introduces higher operational costs and complexity.
Lighthouse scores use Lab Data, while the Core Web Vitals report in Google Search Console uses real user data (Field Data) from the Chrome User Experience Report, and the two may differ significantly.
The core metrics of the Lighthouse performance score include FCP, LCP, TBT, CLS, and Speed Index.
Lighthouse's audit engine communicates with the browser kernel based on the Chrome DevTools Protocol (CDP).
Lighthouse's audit engine communicates with the browser kernel via the Chrome DevTools Protocol (CDP) and adopts a Gatherer-Auditor architecture, where Gatherers are responsible for collecting raw data and Auditors evaluate based on predefined rules and generate recommendations.
Lighthouse performance score core metrics include FCP, LCP, TBT, CLS, and Speed Index, with each metric converted to percentile scores based on the distribution of the HTTPArchive real-world website dataset.
The AI Agent can directly invoke Lighthouse's inspection capabilities, read audit results, and autonomously navigate to the problematic location in the source code to make modifications.
Lighthouse's audit system covers five dimensions: Performance, Accessibility, Best Practices, SEO, and Progressive Web Apps, giving a composite score of 0–100 for each dimension.
Google announced the direct integration of the Lighthouse tool into the AI Agent workflow within Chrome DevTools.
