WURFL.js is a client-side JavaScript library that enables real-time detection of device models and capabilities for websites and web applications. By embedding a single JavaScript snippet, WURFL.js queries ScientiaMobile’s cloud-based WURFL Device Description Repository (DDR) to identify the accessing device’s type, model, form factor, operating system, and other characteristics. The detection process leverages the User-Agent string and, when necessary, additional client-side logic to distinguish between closely related devices (such as different iPhone models). The resulting device information is returned as a JavaScript object, allowing developers to tailor content, layout, and functionality to the user’s device. WURFL.js is available in free and commercial (Basic, Standard, Pro) editions, with commercial versions providing more detailed device data and advanced capabilities. The solution is widely used for responsive design optimization, analytics, targeted content delivery, and improving user experience across a broad range of devices, including smartphones, tablets, smart TVs, and game consoles.
