Cocoa (OS X) vs webapp2: What are the differences?
What is Cocoa (OS X)? The Cocoa frameworks consist of libraries, APIs, and runtimes that form the development layer for all of OS X. Much of Cocoa is implemented in Objective-C, an object-oriented language that is compiled to run at incredible speed, yet employs a truly dynamic runtime making it uniquely flexible. Because Objective-C is a superset of C, it is easy to mix C and even C++ into your Cocoa applications.
What is 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.
Cocoa (OS X) and webapp2 can be categorized as "Frameworks (Full Stack)" tools.
