The Best Free Website Speed Test Tools

After years of working on websites I’ve gathered a constantly updating list of my favorite tools. Below I’ve compiled my list of the best free website speed tests with their features. Enjoy!

GTmetrix Website Speed

GTmetrix is by far my favorite, it pulls data from Google’s Page Speed Insights and Yahoo’s Yslow services along with their own additional tests and metrics. Even the free tier offers a ton of great features, for example you can keep a history if you test the same page more than once, you can change the browser and browser extensions that are used for the test, you can change the location the test is from, and more. Upgrading to Pro adds even more features.
