WhatIsMyBrowser.com Frontend Detection Library

Our Frontend Library makes it easy to detect a number of things about your customer's web browser.

Written in Javascript, it runs in your visitor's web browser and will detect things such as Third-Party Cookie support, AdBlockers and so on. Used in conjunction with our Browser Detection API, you will get a very clear picture of your customers web browsing system and configuration.

We've made it free to use on your own website. Please read and agree to the Terms & Conditions before you start using the library.
