Detect Your Browser User-Agent Online — 101IP

The User-Agent page on 101IP helps you find out which browser, operating system and device are being used to access the internet. We parse the navigator.userAgent string using UAParser.js and display the data in a clear, human-readable format.

What is a User-Agent and why does it matter?

A User-Agent is a text string that your browser sends to servers in HTTP headers. It can reveal:

browser name and version (Chrome, Firefox, Safari, etc.);
operating system (Windows, macOS, Linux, Android, iOS, etc.);
device type: desktop, laptop, smartphone, tablet;
CPU architecture and other technical parameters.

What does the User-Agent detector show?

Browser — name and version detected from User-Agent;
Engine — rendering engine (Blink, WebKit, Gecko, etc.);
OS — operating system family and version;
Device — vendor, model and device type if available;
CPU — processor architecture (x86, x64, ARM, etc.);
Languages and timezone — locale and time zone from your browser;
Screen and DPR — screen resolution and pixel density;
Online status and touch — whether touch input and network connection are present;
Raw User-Agent — full string with one-click copy.
