Google Lighthouse
Google Lighthouse is an open-source, automated tool for improving the quality of web pages. It audits web pages for performance, accessibility, progressive web apps (PWA), SEO, and best practices, providing actionable reports with scores and recommendations. It can be run from the command line, as a Node module, or directly in Chrome DevTools.
Developers should use Lighthouse to identify and fix issues that impact user experience, such as slow loading times, poor accessibility, or non-compliance with web standards, which is crucial for optimizing websites for search engines and users. It is particularly valuable during development and testing phases to ensure web applications meet performance benchmarks and accessibility guidelines, helping teams deliver high-quality, inclusive digital products.
