Lighthouse Extension

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.

Carlos Espinoza (ID: 000000bcfa3e77fc) Voted 3 ★ - Updated 02/09/2023 New update that removes it from the developer tools limits the functionality to only giving it an URL. This limits websites that use auth in different ways such as cookie tokens, tab exclusive auth tokens, etc. It opens on a new tab which I rather not.
