Phalcon vs. Revel vs. Fat-Free

Phalcon is a web framework implemented as a C extension offering high performance and lower resource consumption.

Revel makes it easy to build web applications using the Model-View-Controller (MVC) pattern by relying on conventions that require a certain structure in your application. In return, it is very light on configuration and enables an extremely fast development cycle.

Fat-Free Framework makes it easy to build entire Web sites in a jiffy. With the same power and brevity as modern Javascript toolkits and libraries, F3 helps you write better-looking and more reliable PHP programs.
