How this page works
Browsers describe themselves to the pages they open. This page reads that description, plus a few settings such as your language and time zone, and turns them into plain English. It also checks for features that the tests on this site rely on, so you can see at a glance why something might not work.
Version numbers can be approximate: some browsers deliberately hide the exact version or the operating system to make users harder to track.

Frequently asked questions
Why does it say Windows 10 when I have Windows 11?
Some browsers report both as Windows 10. Chrome and Edge give the real version, which this page uses when it's available.
What does "Cores" mean?
It's the number of processor threads your device lets the browser use. Some browsers round this down for privacy.
