How to read it

Parse UA, Client Hints, browser, OS and bot clues.

01

Windows 11

Regular UA strings often still show Windows NT 10.0; Windows 11 needs Client Hints platformVersion context.

02

Client Hints

Chrome / Edge can expose brands, platform, architecture, bitness and full versions; some fields are async.

03

Bot detection

UA keywords such as bot, crawler, spider, Headless or Selenium move the result to review or fail.
