Karma vs Phabricator: What are the differences?

What is 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.

What is Phabricator? Open Source, Software Development Platform. Phabricator is a collection of open source web applications that help software companies build better software.

Karma belongs to "Browser Testing" category of the tech stack, while Phabricator can be primarily classified under "Code Review".

Some of the features offered by Karma are:

  • Test on Real Devices
  • Remote Control
  • Testing Framework Agnostic

On the other hand, Phabricator provides the following key features:

  • reviewing code before it hits master
  • auditing code after it hits master
  • hosting Git/Hg/SVN repositories

"Test Runner" is the primary reason why developers consider Karma over the competitors, whereas "Open Source" was stated as the key factor in picking Phabricator.

Karma is an open source tool with 10.7K GitHub stars and 1.61K GitHub forks. Here's a link to Karma's open source repository on GitHub.

According to the StackShare community, Karma has a broader approval, being mentioned in 119 company stacks & 57 developers stacks; compared to Phabricator, which is listed in 52 company stacks and 12 developer stacks.
