Check it out at web.dev, which is the actual URL.



They have two main sections. One is called Learn, where they give you tons of information about various topics like speed optimization, network resilience, security, accessibility, and more including progressive web apps.

The other main section is called Measure, where you'll punch in your website homepage or any inner page and get measurements. If you have advertisements, be prepared for low scores for crap you can't control, as always!

It's pretty slick and provides a lot more information that services like Pingdom and WebPageTest and GTMetrix don't, but also lacks some of the insight those provide too.

There's a lot to be learned from it, there doesn't seem like there will be queueing issues where you wait in line, and you can log in with your Google account and keep a record of your scores to make sure you're improving.

I'm curious if that chrome plugin is using the site you have loaded in your browser. Or is it loading it from the web? I ask because I often do dev work on domains with PW protected directories or I use my hosts file to test sites that aren't "live". I'm wondering how I can figure out what site the report is loading from.

Make an update to the host edited version like remove a 3rd party script and see if it reports the removal of the script, or addition of some large image.

I believe it's using the current site loaded since it takes about 20-30 seconds to run.

I finally got around to testing this and unfortunately it does not load from your current machine. It definitely goes out to the web to pull the publicly available site. Too bad.
