Karma vs LambdaTest: 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 LambdaTest? Perform Cross Browser Testing on 2000+ Real Browsers and Operating System Online. LambdaTest is a cloud-based testing platform and it provides access to a powerful network cloud of 2000+ real browsers and operating system that helps testers in cross-browser and cross-platform compatibility testing.

Karma and LambdaTest belong to "Browser Testing" category of the tech stack.

Some of the features offered by Karma are:

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

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

• Selenium Web Automation
• Real-time testing of web app on cloud based desktop and mobile browsers
• Test your locally hosted web app using SSH Tunnel feature

"Test Runner" is the primary reason why developers consider Karma over the competitors, whereas "Integration with Gitlab" was stated as the key factor in picking LambdaTest.

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.
