How to use it

  1. Open the page in the browser you want to inspect.

  4. Compare results across browsers if you are troubleshooting compatibility.
What is User Agent?

Parse device, browser, and operating system details from the incoming user agent string.

How it works

The page reads the User-Agent string sent by your current browser, then separates its browser, operating system, and device clues. The string is a compatibility hint and can be reduced or changed by privacy settings.

Common uses
  • Check the browser identity a website receives during a support session.
  • Compare browser and device strings when diagnosing a rendering difference.
  • Copy environment details into a bug report without searching browser settings.
Limitations
  • Results depend on the browser, network, input, and external service involved.
  • This tool is informational and does not replace specialist diagnostics or professional advice.
Frequently asked questions
Can a website identify my exact device from this string?
No. User-Agent strings provide broad browser and platform hints, are often reduced, and can be spoofed; they are not a reliable unique device identifier.
Why does the User-Agent say Chromium for another browser?
Many browsers share Chromium's rendering engine and include compatibility tokens so websites serve compatible content.
Is the User-Agent always accurate?
No. Browser privacy features, extensions, and compatibility modes can alter or reduce the string.
