Lighthouse is an automated auditing tool for web pages. It checks performance, accessibility, and other website qualities, helping developers turn a vague concern about page quality into findings they can investigate.
Find problems in a product page
Audit a page when loading behavior, accessibility, or search-facing details need attention, with diagnostics tied to specific aspects of the implementation.
Check a change with repeatable analysis
Use the audit as part of evaluating a website update. It provides a consistent starting point for comparison, alongside actual user and browser testing.
