In the past, web standards were very confusing. Either most of the features are not compatible with every browser, or their implementation is different. Even if the picture is a lot better today, cross-platform testing is still utterly essential. However, there are instances where you may notice some websites breaking on one browser but running smoothly on another. It happens when a particular website has not been tested thoroughly on all existing web browsers.

In the virtual world, your website shows your personality. Every browser offers some unique features, but along with some limitations. It is next to impossible for any developer to maintain a library of mobile devices and desktops representing a demographic region. That is when cloud tools come in and play an important role. Most cross-platform testing tools run on clouds, which helps you to get comprehensive data. In this article, we share a list of top tools that will help you find and debugging errors that might be the result of incompatibility.

To help you ensure that your website runs smoothly on all browsers, you need to use cross-platform testing tools. These tools will help you understand how your website will perform on each web browser.

How to Select A cross-platform Testing Tool?

Cross platform testing is an essential step, preferably a formality of testing your website or application on all browsers. It helps to improve the performance of your website. Here are some of the things to look out for:

  • Code validation: Does your application or website report code errors?
  • Performance: Is your website slow or crashes from time to time?
  • UI inconsistencies: Are there any flaws with the design or the theme of your website?
  • Responsive design: Is your website design responsive enough?

A cross-browser tool should be capable enough to resolve all the errors you face with your website or application. A tool that provides the user with an in-depth analysis with a screenshot is the best.

What happens if I don’t use the Cross-browser test?

Inconsistencies are the new normal for most websites. Each browser renders each website differently. Also, some browsers might not support features that run entirely on others. Your aim should be to ensure that your website runs smoothly on the most popular browsers. If your website is not accessible on most websites, it will directly impact your revenue (among other things).

For instance, an eCommerce with maximum errors and crashes will not increase their revenue compared to a site with fewer errors and crashes. According to a survey conducted, most businesses ensure a loss of $59,400 every year due to website crashes.

Which Browsers are Important for Cross-Platform Testing?

Recently Microsoft announced they would be using V8 or Blink instead of their Chakra or EdgeHTML engine. It also means that the majority of the web browsers now will offer similar code compatibility. It might seem to be a step back in terms of healthy competition – a website that worked perfectly only on Google Chrome is most likely to run correctly on other web browsers like Brave and Opera. This, combined with the decreased usage of Internet Explorer, cross-platform testing has become extremely important.

Technically, your website or application should be working correctly on web browsers that are used by users and customers on a large scale regularly. Below we have mentioned some of the popularly used web browsers along with user percentage:

  • Chrome: 60%
  • Safari: 15%
  • Firefox: 5%
  • UC Browser: 4.5%
  • Internet Explorer: 3%
  • Opera: 3.15%
  • Microsoft Edge: 2%

Every tool mentioned on our list has decent features. It is almost impossible to find a free cross-platform testing tool online. But most tools listed by us come with a free trial period.
