Meteor is a JavaScript framework that can help you with your web, mobile, and desktop development projects through technologies you already know and use. Thus, you can combine a series of elements you are familiar with and just worry about the specific features of your project. Besides, you can create apps that are less bloated thanks to an integrated JavaScript stack and make them work in a wide variety of systems and devices. 

Meteor, or MeteorJS, is a free and open-source isomorphic JavaScript web framework written using Node.js. Meteor allows for rapid prototyping and produces cross-platform (Android, iOS, Web) code.
