Lighthouse | Glossary

Lighthouse is an open-source auditing tool from Google that generates lab metrics and recommendations for performance, accessibility, SEO, and best practices. It can run in Chrome DevTools, CI, or via the CLI.

Why it matters: Lighthouse provides repeatable lab tests for diagnosing issues and tracking improvements over time.

Quick tips:

Use consistent throttling profiles for comparable results.
Treat scores as diagnostics, not goals; fix the underlying issues.
Pair with RUM for real-world validation.
