User Agent strings come in all shapes and sizes, and the number of unique user agents is growing all the time. We've collected millions of user agents and have categorised them here for you, based on some of the things we can detect about them - Operating System, Browser, Hardware Type, Browser Type, and so on.
Our user agent parser and our database of user agents is powered by the millions of user agents we collect on whatismybrowser.com.
You can browse an organised collection of them below (or you can parse a custom user agent here).
If you need to integrate our user agent parser directly into your website or system then it's very simple to use our API. It's free to use with paid tiers for more access and better features. This lets you identify the browser, OS and device your users have. Find out more.
If you want to get our database of more than 2,100,000+ user agents you can download it very easily. This will let you do things like advanced filtering and searching, identify trends in user agents, perform statistical analysis and other interesting applications. Weekly downloads are available on our more advanced API tiers. Find out more.
