WURFL

In addition, the developer can specify other content decisions be made at runtime based on device specific capabilities and features (which are all in the WURFL).

[5] While the WURFL Cloud is a paid service, a free offer is made available to hobbyists and micro-companies for use on mobile sites with limited traffic.

WURFL.io features non-commercial products and services from ScientiaMobile: WALL (Wireless Abstraction Library by Luca Passani) is a JSP tag library that lets a developer author mobile pages similar to plain HTML, while delivering WML, C-HTML and XHTML Mobile Profile to the device from which the HTTP request originates, depending on the actual capabilities of the device itself.

As a result of the "no-derivates" clause, users are no longer permitted to add new device capabilities to the WURFL file either directly or through the submissions of "patches".

On January 3, 2012, ScientiaMobile filed a DMCA takedown notice against the open-source device database OpenDDR that contains data from a previous version of WURFL.

[16] On March 22, 2012 it was announced by Matthew Weier O'Phinney that Zend Framework would be dropping support for WURFL as of version 1.12.
