We have a huge collection of over 410 million different user agents. Look around to find user agents for which ever browser, operating system, device, software type or layout engine you need. If you need to decode a user agent, use the User Agent Parser or the Browser Detection API.
We've been decoding user agents for more than 13 years and we've seen it all - the good, the bad and the downright weird! This website is a collection of resources dedicated to understanding and working with user agents, including the new proposal which may end up eliminating user agents: Client Hints.
As well as this, we've also got resources (such as our Frontend Library) dedicated to detecting frontend web browser features and settings, so that you can understand what technology your website visitors are using and help solve their technical problems. It's the same technology we use on whatismybrowser.com.
You can use our user agent parser form to paste in a user agent and decipher it. If you want to automate sending lots of user agents, then look at our Browser Detection API - not only will it let you easily decode millions of user agents, it will tell you if your visitor's web browsers are up to date or if someone is trying to send you a dangerous or weird user agent. Our API has lots of helpful features and is trusted by thousands of companies - check it out now.
