Google Pagespeed Insights vs. Lighthouse

The million-dollar question is that if performance insight is provided on a website’s backend, then why do you require Google Lighthouse?

The answer is quite simple. Google Lighthouse tests your website while Google Pagespeed only tests the speed.

The significant difference between Google Pagespeed and Google Lighthouse is that the former focuses only on speed and later auditing other performance aspects. If you want a comprehensive report and suggestions for your website performance, then Google Lighthouse is the tool for you. On the other hand, Google Pagespeed Insight is the tool to tell you precisely what your viewer is experiencing at your website.

These are different tools but note that Pagespeed Insight uses Lighthouse data and combines it with real-world information to show a brief report of your webpage performance.
