Lighthouse is an  open-source, automated tool for auditing and improving the quality and performance of web pages.

It’s a popular choice due to its versatility and ability to measure different metrics like best practices, SEO - search engine optimization, and more…

Before jumping on how to use Lighthouse, the basic question here is:

WHY Lighthouse?

• To keep an eye on the site with respect to the web-standards.
• Lighthouse not only provides metrics but also generates an actionable report referring to specific DOM elements, CSS selectors or infrastructure setup.
• Instead of waiting for the project completion, lighthouse is helpful in getting the audits in the early stage and alarming issues can be resolved beforehand.
• Lighthouse can be used before starting extensive performance testing using other performance tools like Gatling, JMeter, BlazeMeter, etc.

Run Lighthouse

• Within Chrome DevTools
• As a Chrome Extension
• Via Lighthouse CLI

Note: Chrome Browser should be pre-installed.
