You’ve started your online business, and it starts doing well after some time, but have you checked your business website compatibility across all the browsers that visitors use to access it?

No? Then it’s time to think about it.

Let’s consider that your web app performs well across Mozilla and Chrome browser, but it doesn’t look attractive and works inappropriately across other browsers; what will happen when an individual uses any other browser to visit your site? You would lose a visitor or maybe a potential user.

Therefore, it is required to test the browser compatibility of your website across all the required browsers, for which you need a cross-browser compatibility testing tool. However, you can also choose traditional methods to test cross-browser compatibility; they will consume a lot of time, resources, efforts, and costs because you’ll have to load your web app on computers and mobile devices to test it in a combination of browsers. Thus, it’s ideal to choose a cross-browser testing tool for browser compatibility testing.

In this article, we have compared the top ten cross-browser testing tools of 2019. Before proceeding to that, there are some other things that you should know about cross-browser testing.

Cross-Browser Testing

Cross-browser testing is an essential task that needs to be executed on your web app to ensure that it delivers a fantastic and consistent user experience across all browsers, devices, and operating systems that visitors could use to access your website. Delivering the same user experience across all combinations will help you get more users while increasing your sales.

What Needs to Be Tested in Cross-Browser Testing?

A few factors that need to be tested while performing cross-browser testing are:

  • CSS validation, HTML or XHTML validation
  • Page validation by enabling or disabling JavaScript
  • Page layout in multiple screen resolution
  • Ajax and jQuery functionality
  • Font size validation, all images, and alignment
  • Header and footer section
  • Page styles and date formats
  • Special characters with HTML character encoding or

Any such element that is not working properly in other browsers, OS, and devices. Knowing these factors, you might have understood why it is feasible to choose a cross-browser testing tool over traditional cross-browser testing techniques.

Now, let’s take a look at 10 different cross-browser testing tools.

1. LambdaTest

The first tool in our list is LambdaTest. It is a cloud-based testing platform that offers cross browser testing across a combination of more than 2,000 browsers, OS, and devices for free. The specialty of LambdaTest is that it provides both manual as well as automated cross-browser testing for your web app. So, people who are willing to perform real-time cross-browser testing, live interactive testing, or visual testing of their app can opt for the manual process, whereas individuals who want to automate their testing process can run automated Selenium scripts on LambdaTest’s scalable cloud grid. Also, when it comes to price, LambdaTest offers the most affordable pricing plan at $15/month with a bucket full of features.

However, it allows you to automate cross-browser testing across a combination of 1,000+ browsers, OS, and devices by running Selenium and Appium test scripts, which is less compared to LambdaTest.
