Lighthouse Review 2026
Automated tool for improving the quality of web pages.
What is Lighthouse?
Google Lighthouse is a free, open-source automated tool for auditing the quality of any web page. Built into Chrome DevTools and available as a standalone CLI, Lighthouse runs comprehensive tests across five categories: Performance, Accessibility, Best Practices, SEO, and Progressive Web App compliance. Each audit generates a 0-100 score with specific, actionable recommendations for improvement. For SEO, Lighthouse checks meta tags, crawlability, structured data, mobile-friendliness, and link integrity. The tool can be integrated into CI/CD pipelines to catch performance regressions before deployment. Lighthouse powers the PageSpeed Insights API and is the engine behind web.dev performance recommendations. Originally released in 2016 by Google, it remains the definitive standard for web page quality assessment.
Founded in 2016, Lighthouse has established itself as a leading solution in the technical space. It serves SEO professionals, digital marketing agencies, freelancers, and in-house marketing teams worldwide.
