BrowserStack vs Karma: What are the differences?

BrowserStack: Instant access to a lab of 1000+ real mobile and desktop browsers for testing. Live, Web-Based Browser Testing Instant access to all real mobile and desktop browsers. Say goodbye to your lab of devices and virtual machines; 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.

BrowserStack and Karma can be categorized as "Browser Testing" tools.

Some of the features offered by BrowserStack are:

  • Real Device Cloud. Test on a range of physical Android and iOS mobile devices and tablets for the most accurate results
  • 1100+ desktop browsers. Latest versions of IE, Edge, Safari, Chrome, Firefox and more on a range of Windows and OS X platforms on a robust cloud infrastructure
  • Test dev environments. Our Local Testing feature allows you to test development and internal websites seamlessly, without setup or configuration

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

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

"Multiple browsers" is the primary reason why developers consider BrowserStack over the competitors, whereas "Test Runner" was stated as the key factor in picking Karma.

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, BrowserStack has a broader approval, being mentioned in 577 company stacks & 238 developers stacks; compared to Karma, which is listed in 119 company stacks and 57 developer stacks.

    #OpenSource

    I am working on #OpenSource file uploader. The uploader is the widget that other developers embed in their apps. It should work well in different browsers and on different devices. BrowserStack and Sauce Labs help to achieve that. I can test the uploader in many varieties of browsers+OS only used my browser without virtual machines.

    It's incredible how much this service has increased my productivity when it comes to testing new features in multiple browsers. And not only multiple browsers, multiple operating systems as well! And really LOVE that you can run it locally.

    We use BrowserStack to run end to end tests with Selenium on our dashboard. It runs automatically before every deployment and cancels it if anything is out of place.
