Free tool · Google's own tests
X-ray your site
Type your address. Your browser asks Google PageSpeed Insights to test it, and the scores appear next to the standard every Stewart Code page is built to. Nothing here is a sample number.
Test any public website
A test takes 20 to 60 seconds. It runs on Google's servers through the free PageSpeed Insights API, which has a shared daily limit; if Google says the limit is reached, the same test runs on pagespeed.web.dev.

"Ours" is this site's home page, tested the same way at the same time. Real-user rows come from Google's Chrome UX Report and show "no data" when a site has too little traffic. The standard column is our launch standard for scores and Google's "good" thresholds for real users (web.dev).
X-ray this page
See inside any page of this site
Press the X-ray button in the header on any page. It outlines the headings, shows the structured data behind each section, times the page load in your own browser and shows what an AI assistant reads. It runs entirely in your browser and loads only when you press it.
Questions
About the X-ray
Where do the numbers come from?
From Google PageSpeed Insights, called from your browser at the moment you press the button. We do not store, edit or estimate any of them.
Why do my scores change between runs?
Lab tests vary a little with network and server load. That is why our launch test takes the lowest of five runs.
What if Google says the daily limit is reached?
The free API has a shared daily limit. Run the same test on pagespeed.web.dev, or try again later.
Is this the full audit?
No. It is a preview. The Deep Audit is a person reviewing up to 25 of your pages, with a prioritized fix list. If the X-ray shows a slow site, the Speed Sprint fixes your top templates.
