Hello! I am trying to embed the Google Pagespeed page on my website and I keep getting the following error displayed: 403. That’s an error. We’re sorry, but you do not have access to this page. That’s all we know.
If you are the server administrator of that site. Otherwise no.
You could build an app with node since lighthouse is open source. Or you might consider a screenshot, or using GTMetrix to create a PDF report and display it / link to it.
