Google Lighthouse is an open-source web page auditing tool developed by Google's Chrome team and released in 2016. It loads a page, measures categories such as performance, accessibility, best practices and search engine optimization (SEO), and produces a report with scores and suggested improvements.

It can be run from the developer tools in the Chrome browser, as a command-line interface (CLI) or as a Node.js module, so it is also used for automated checks in development workflows.
