Karma vs Nitrous.IO: What are the differences?

Karma: Spectacular Test Runner for JavaScript. Karma is not a testing framework, nor an assertion library. Karma just launches a HTTP server, and generates the test runner HTML file you probably already know from your favourite testing framework. So for testing purposes you can use pretty much anything you like; Nitrous.IO: Making coding in the cloud a reality. Get setup lightning fast in the cloud & code from anywhere, on any machine.

Karma belongs to "Browser Testing" category of the tech stack, while Nitrous.IO can be primarily classified under "Cloud IDE".
