Cuca is a light web development framework that supports CGI and FastCGI. It has a widget-bases approach to reuse functionality and does not implement an MVC architecture. Content can be generated directly by the controller with the help of external widgets that can generate code using markaby, eruby or any other user implemented 'generator'. It supports pretty URL's, layouts, sessions and the rendering of 'partials'.
