Google Lighthouse is an open-source tool developed by Google for auditing the quality and performance of web pages. It provides a comprehensive analysis of five key aspects: Performance, Accessibility, Best Practices, SEO, and Progressive Web App (PWA) capabilities. By running a Lighthouse audit, developers can receive detailed insights and recommendations to improve load speed, accessibility for all users, adherence to best practices, search engine optimization, and the functionality of PWA features. Lighthouse audits can be run directly in Chrome DevTools or through the command line, making it an essential tool for developers focused on enhancing site performance and user experience.
