DeviceDetector is a precise and fast user agent parser and device detector written in Ruby, backed by the largest and most up-to-date user agent database.

DeviceDetector will parse any user agent and detect the browser, operating system, device used (desktop, tablet, mobile, tv, cars, console, etc.), brand and model. The gem detects thousands of user agent strings, even from rare and obscure browsers and devices.

The code is optimized for speed of detection, by providing optimized code and in-memory caching.

DeviceDetector has been ported to Ruby and open-sourced by the Podigee team, as part of our give-back to the community.
