This page shows you what your web browser is sending in the "User-Agent" header for your HTTP requests. Want to know what headers your browser is sending?
Each bit of your user agent indicates something particular about your system.
There's no "standard" way of writing a user agent string, so different web browsers use different formats (some are wildly different), and many web browsers cram loads of information into their user agents. That's where WhatIsMyBrowser.com steps in - we decode your user agent string to figure out everything it's saying.
Check out our user agent analyser page, which gives you a neat breakdown of all the things we can tell you about your browser and computer based on your user agent. We have a User Agent API if you need to use the detection in your own system too.
It is possible to change or "fake" what your web browser sends as its user agent. Some mobile web browsers will let you change what the browser identifies itself as (ie "Mobile Mode" or "Desktop Mode") in order to access certain websites that only allow desktop computers. If you change this setting, the user agent is what is affected.
If you'd like to see lots of other user agents that this site has been sent, check out our User Agents page.
What are user agents all about and what are they used for?
Does changing your user agent help?
