PHP-MVC vs webapp2: What are the differences?

PHP-MVC: Simple and easy to understand MVC skeleton application. This project is - by intention - NOT a full framework, it's a bare-bone structure, written in purely native PHP ! The php-mvc skeleton tries to be the extremely slimmed down opposite of big frameworks like Zend2, Symfony or Laravel; webapp2: Lightweight Python web framework compatible with Google App Engine’s webapp. webapp2 is a simple. it follows the simplicity of webapp, but improves it in some ways: it adds better URI routing and exception handling, a full featured response object and a more flexible dispatching mechanism.

PHP-MVC and webapp2 can be primarily classified as "Frameworks (Full Stack)" tools.
