My User-Agent tester

Go on, put us to the test. Try our User-Agent and other HTTP header parser below and we’ll show you what information we can get.

As Google press on with User-Agent Client Hints and the deprecation of the User-Agent, you may wish to use Client-Hints headers for an accurate detection. Our parser accepts both the User-Agent HTTP request header and User-Agent Client Hints.

You can even use our User-Agent and User-Agent Client Hints Parser in your own environment: download the 51Degrees UAParser from NPM.

Your HTTP headers have been automatically added below. Alternatively, you can paste your own HTTP headers with the format headername: headervalue, with one header per row, into the box to test. Once you're happy, press the submit button to see what you get.
