Grails vs. FuelPHP vs. Kohana

Grails is a framework used to build web applications with the Groovy programming language. The core framework is very extensible and there are numerous plugins available that provide easy integration of add-on features.

FuelPHP is a fast, lightweight PHP 5.4 framework. In an age where frameworks are a dime a dozen, We believe that FuelPHP will stand out in the crowd. It will do this by combining all the things you love about the great frameworks out there, while getting rid of the bad.

Kohana is an elegant, open source, and object oriented HMVC framework built using PHP5, by a team of volunteers. It aims to be swift, secure, and small.
