Cocoa (OS X) vs Geddy: What are the differences?

Developers describe Cocoa (OS X) as "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. On the other hand, Geddy is detailed as "A simple, structured web framework for Node". Geddy is a full stack open source MVC framework based on ruby on rails methodology with built-in authentication module, passportjs and socket.io integration.

Cocoa (OS X) and Geddy belong to "Frameworks (Full Stack)" category of the tech stack.

Geddy is an open source tool with 1.9K GitHub stars and 270 GitHub forks. Here's a link to Geddy's open source repository on GitHub.
