Neutron Drive vs Codepen

Collaborating with Neutron Docs works similar to Google Docs. You can invite a friend/coworker for pair program or assistance

You can enable auto save with changes tracking and get minute to minute tracking of changes. But not good for tracking time spent on a projects because every 30 days or 100 changes gets automatically deleted.

CodePen makes it really easy to export code as a zip or Github Gist.

CodePen has an impressive amount of support for preprocessors (such as Jade, Haml, Slim, Sass, Less, Stylus, Coffeescript and PostCSS). There is also plenty of frameworks and libraries to pick from (Foundation, Bootstrap, Angular, D3, Backbone, Ember etc.).

The codepen profile page allows you to display all of your public pens, and control which order you want them to be viewed in. This is great for showing off your work to possible employers, other devs etc..

To fork a pen only requires clicking one button, and you'll be able to modify the pen on your own account.

You can search through other pens, either by keyword or popular, picked or recent.
