Limitless integration options

No matter what kind of system or website you have, as long as you can make HTTP requests and parse JSON, you can integrate with us.

Unlike other user agent parsing libraries, it doesn't matter what programming language or CMS you've used for your website or system, simply by sending a HTTP request you can access our highly detailed parse results.

Our customers use a range of different languages including JavaScript, PHP, Python, DotNet, Java, Ruby, ColdFusion and even Microsoft Excel!

Set and Forget

Are you Sick of always updating software libraries? Don't bother any more.

Use our API and you'll always be using the latest version of the user agent parser. No libraries to download and maintain; just send a HTTP request and be confident that you're always getting the latest and greatest results.

That's one less thing for you to worry about!

The best of breed

Sure, there are other user agent parsers out there, but you're looking at the best one.

Free to use, and reasonably priced for extra features

We believe everyone should have access to the best user agent parser, so we've made the API free to use. If you need a larger monthly quota and access to more features then you can support us with a paid tier. Easy!

World class support, regardless of your plan

There's nothing worse than being stuck and not being able to get help - we want you to have an easy and enjoyable time using our API - the whole idea of the API is to make your life as a developer easier, so why shouldn't that extend to the support for it as well! We'll do whatever it takes to get you up and running regardless of your API plan.

The perfect balance of detail and ease of use

Some customers just want to be able to use the same browser detection as the homepage of in their own systems; so that's easy to do with our API. Other customers want to get all the nitty-gritty details of their user's browsers, including software types, hardware types, platforms, plugins and so on - and that's easy to do too.

Excellent documentation and sample code to get you started

You won't be left in the dark - we have a detailed API specification, a thorough integration guide and helpful sample code to get you off and running.

Constantly maintained and expanded

We use the millions of user agents we've collected from the homepage of to power our constant expansion of our user agent parser. Other parsers get updated occasionally; we're always adding more detection.

Built with love and care

It might sound strange, but what started as a side-project done in our spare time eight years ago has grown from a hobby into a fully fledged endeavour that we live and breathe. We really care about providing the best product and service. This is our niche and we own it.


  • LUXE customers are a global bunch who use a wide range of devices. We adopted API to detect their system details, so we know exactly what they're using (and don't have to bother them with such trivial questions when they make contact). The API saved us heaps of development time, freeing us up to focus on the fun stuff!

  • We are really happy with the service you provide, so useful!

  • We needed a HTTP OPTIONS response added to the API so that we could integrate with our system. We were throughly impressed with the responsiveness of the API team when they built it for us within hours! We're now all hooked up and working.

  • Brett and the crew at worked really hard to deliver us a product in the user-friendly form of an Excel file. This Excel file allows members of our team who have no knowledge of programming languages, to queue user-agent strings and utilise the whatismybrowser API.

    Extracting results and categorising our customers by the type of device they use has never been quicker!

    Also, Brett’s communication is A+

  • The API really helps manage our visitors, especially mobile devices of all kinds.
