Lighthouse is an open-source, automated tool that analyzes and audits web apps and web pages in order to improve their quality. Lighthouse collects modern performance metrics and insights on developer best practices; auditing for performance, accessibility, SEO and more. After auditing it produces a report either in JSON or HTML. Included in the report is a reference doc that explains the importance of the audit and how to fix the problem areas, which you can use to improve the web app or web page.
Lighthouse can be integrated directly into the Chrome DevTools with its own panel. To run it, you would simply have to select the Lighthouse panel and click on "Generate report". It can also be run from the command line, or as a Node module.
