MEAN vs Volt: What are the differences?

Developers describe MEAN as "A Simple, Scalable and Easy starting point for full stack javascript web development". 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. On the other hand, Volt is detailed as "A ruby web framework where your ruby runs on both server and client". Volt is a ruby web framework where your ruby code runs on both the server and the client (via opal.) The DOM automatically update as the user interacts with the page. Page state can be stored in the URL, if the user hits a URL directly, the HTML will first be rendered on the server for faster load times and easier indexing by search engines.

MEAN and Volt belong to "Frameworks (Full Stack)" category of the tech stack.

"Javascript" is the primary reason why developers consider MEAN over the competitors, whereas "Handlebars" was stated as the key factor in picking Volt.

MEAN and Volt are both open source tools. It seems that MEAN with 11.8K GitHub stars and 3.57K forks on GitHub has more adoption than Volt with 3.3K GitHub stars and 209 GitHub forks.
