It doesn’t really. The website thinks I’m on a iPhone 19 pro, although I’m actually on a iPhone SE 1st gen. So it’s off by roughly a decade.

Maybe that's one of Safari's numerous 'quirks' our frontend devs keep bitching about.

Which in this case Im thankful that Apple isn't too keen on following standards like these.

I wish the website could tell us how life is like in 2027!

Mine is radically off as well. Says I've got a GeForce 980 or equivalent with 4GB instead of a 5090. I'm guessing the detection only really works on Chromium based browsers.

This stuff is used a lot in browser fingerprinting for tracking purposes. More privacy-focused browsers usually feed randomized info.

The latest Librewolf prompted me to allow the site permission to make a WebGL context. That's what it used for hardware detection.

It couldn't guess any of my hardware specs when I opened the page in Safari on my Mac.

I thought that's how airlines do the whole trickery around having different pricing if you access the site from Windows or Mac...
