This extension shows web vitals metrics for the current page and lets you quickly navigate to PageSpeed Insights, WebPageTest, and Treo Site Speed. For PageSpeed Insights tests we also show the original observed data along with the simulated metrics.

Looks good! Do the initial stats that appear on the top come from a lab test?

@colinmcdermott It's data directly from the site you're on! So it is technically lab data, where your computer is the lab environment.

Hi everyone! I often want to run more in-depth tests on the page I'm on, so I built this extension to make it easy to access different tools. I also often see PageSpeed Insights report inaccurate lab data, due to the simulated throttling it applies. But, for example, if you can see that the observed metrics are worse than the ones after simulated throttling then it's clearer that the throttling isn't working correctly.

Good!
