14 Best Cross Browser Testing Tools in 2021 (Latest Ranking)

Are you looking for Cross Browser Testing Tools to test your web app for cross browser compatibility. Here in this guide, we have reviewed 14 popular cross-browser testing tools that help you to pick the right choice of yours.

Cross Browser Testing is done to make sure all our site visitors see our site the way we intended to see it even though they use different browsers.

But sometimes we face a situation where a website breaks on one browser works on other browsers. This is because that particular website has not been tested thoroughly on all the existing popular browsers.

To overcome these kinds of situations we need to focus on cross-browser compatibility testing.

To ensure that your site works well in all browsers, here are some popular cross-browser testing tools which you can try out. These tools help you perform cross-browser compatibility testing across various web browsers with several versions, devices, screen resolutions, and operating systems.

You can choose the browser compatibility test tool depending on your needs.

Best Cross Browser Testing Tools

It doesn’t mean that if a website works in Google Chrome, it’ll most likely work in other browsers like Safari, Opera, Firefox, etc., 

Usually, companies follow Google Analytics or some other web analytics tracking software to gather data like how their customers are using their website. Check this Wikipedia link to see the usage share of web browsers worldwide

Usage share of all browsers as of November 2018.

• Chrome: 61.75%
• Safari: 15.12%
• Firefox: 4.92%
• UC: 4.22%
• Opera: 3.15%

What is Cross-browser Testing

Cross Browser Testing is a type of non-functional test which helps us ensure that our website or web application works as expected in various web browsers.

We could do Cross Browser Testing on different browsers both manual and automated way.

To do Cross Browser Testing manually, we (Software Testers) create tests for each browser and execute it manually on each browser.

To do it in an automated way, we could create Selenium tests with multiple conditional statements that execute test cases based on a specified browser type.

Every browser displays a website in their own style. We usually cannot have all the browsers on one machine. Each browser is designed by a different vendor. So each browser has its own features to showcase its unique presence. While testing a website, we need to ensure that our website is appearing the same across all the browsers. To do this we need to have all the browsers.

Fortunately, there are some tools to perform cross-browser testing without testing individually in a manual way.
