GTmetrix Pingdom WebPageTest PageSpeed Insights
Scores and recommendations 27 PageSpeed recommendations and 18 YSlow recommendations Approximately 11 recommendations 6 recommendations 20 Audits/Opportunities

Browsers Firefox (default) and Chrome Uses real browser Firefox, Chrome, Opera, and Edge Emulated browser

From the above comparison chart, we can understand that each test tool has a different sort of data or results. So, it is important to understand how each tool works before relying on them.

We have used these speed test tools for some of our A/B testing work. You can take a look at these articles to learn more.

So, based on our personal view, here are the best tools based on certain use cases.

  • Quick checks: GTmetrix, Pingdom Tools, and PageSpeed Insights
  • In-depth analysis: GTmetrix and WebPageTest
  • SEO check: PageSpeed Insights, GTmetrix, and Pingdom Tools
  • Mobile devices: WebPageTest, GTmetrix, and PageSpeed Insights
  • Advanced options: WebPageTest and GTmetrix

We are using GTMetrix as a base for speed improvements. GTMetrix and other tools like Pingdom and WebPageTest are also developed from Google’s original open-source PageSpeed library with certain customization and modifications. Instead of using all the metrics, GTMetrix has used the rules which are important.

Google PageSpeed Insights seems to be using a few other rules apart from the open-source PageSpeed library which is not a part of the open-source library.

Also, Google PageSpeed Insights & Lighthouse should have the same results. But as per this reference, results seem to be different and the issue is still open.

On the whole, we conclude that GTmetrix is the best speed test tool because it checks all the important use cases that we consider. 

We will update this article, so you will always be aware of a better option arises or if the existing ones don’t meet our standards. We hope that the above information has provided you with the clarity you require.
