Android SDK vs. MEAN vs. Padrino

Android provides a rich application framework that allows you to build innovative apps and games for mobile devices in a Java language environment.

MEAN (Mongo, Express, Angular, Node) is a boilerplate that provides a nice starting point for MongoDB, Node.js, Express, and AngularJS based applications. It is designed to give you a quick and organized way to start developing MEAN based web apps with useful modules like Mongoose and Passport pre-bundled and configured.

Padrino is a ruby framework built upon the excellent Sinatra Microframework. Padrino was created to make it fun and easy to code more advanced web applications while still adhering to the spirit that makes Sinatra great!
