About Lighthouse

Lighthouse is an open-source, automated tool for improving the performance, quality, and correctness of your web apps. When auditing a page, Lighthouse runs a barrage of tests against the page, and then generates a report on how well the page did. From here you can use the failing tests as indicators on what you can do to improve your app. * Quick-start guide on using Lighthouse: https://developers.google.com/web/tools/lighthouse/ * View and share reports online: https://googlechrome.github.io/lighthouse/viewer/ * Github source and details: https://github.com/GoogleChrome/lighthouse
