Three Tools For Website Performance Testing

So you’ve built an awesome looking site. Congratulations! Curious to see how fast it is? Check out these three tools for helping you test the performance of your website.

PageSpeed Insights

Provided by Google this tool will basically run a lighthouse test for you. You’ll get performance statistics for both mobile and desktop as well as metrics on accessibility, SEO, and general best practices.

Even if you’ve run lighthouse tests on your own PC, it’s a good idea to run it again using this tool as it runs in an isolated environment. Sometimes the extensions you’ve installed in your browser can interfere with the lighthouse test.

GTmetrix

This tool is purely focused on performance. The measurements are similar to PageSpeed Insights but it gives a nice waterfall chart for the loading of your site, a video and an option for monitoring/alerting with a free account.

WebPageTest

The most feature rich option of the three this one offers:

  • Option to test from a variety of different devices
  • Option to test from a variety of different Internet connection types
  • Option to test from different locations all over the world
  • Option to test on a re-load
  • Option to test on various web browsers
  • Export reports to a variety of different tools
  • A total of 15 different reports to be gained from a single scan
