When you are trying to use mean stack you will come across two different stacks one is mean.js and other is mean.io. We will look at the differences between these two today. 

Mean.js is a fork of mean.io. They both use swig for templating and karma and mocha for testing, passport integration etc.

Mean.io uses cli tool named mean for scaffolding and boilerplate generation and Mean.js uses Yeoman Generators.

Mean.io uses a more self-contained node packages modularity compared to mean.js. Mean.js uses modules in frontend and connects them with Express.

For deployment, both have Dockerfiles in the repositories.
