In the field of automation testing, Selenium and Katalon are both highly popular due to their powerful capabilities that cater to testers with various needs. You must nevertheless take into account a few significant variations between Selenium and Katalon Platform:

katalon1. Usability

Everything you require is already present on the Katalon Platform. Because of its low-code approach to test automation and user-friendly design, testers with little to no coding knowledge may easily build and execute automated tests. On the Katalon Platform, seasoned users can completely switch to coding mode and develop their own scripts.

Selenium, on the other hand, necessitates a higher level of technical expertise and coding skills in order to fully realize its potential. Each testing framework must be created from scratch. However, because Selenium is an open-source solution, a sizable user community throughout the world contributes resources, documentation, and forums, flattening the learning curve.

katalon2. Test Artifact Administration

When your application scales and your number of test artifacts increases, Selenium does not offer a feature that can keep your testing activities organized. Katalon, on the other hand, offers an all-in-one solution that incorporates test artifact management with its Object Repository. 

Additionally, since applications evolve over time, automation test scripts and objects need to be updated frequently to reflect the change. Organizations may experience considerable maintenance costs if test artifact management is inadequate. 

3. Scripting Language

Only Java and Groovy are supported by Katalon, but a broad variety of languages like Java, C#, Python, Ruby, and others are supported by Selenium. Selenium offers testers the choice of using their preferred language to build test scripts because it is an open-source framework.

katalon4. Licenses

Selenium is an open-source tool that may be used for free, whereas Katalon has a free version as well as premium enterprise editions. Because of this, anyone may use Selenium, and you can increase its functionality by using its plugins. On the other hand, Katalon Platform needs an initial investment but has a tonne of built-in features that help QA teams get going quickly.

The decision between Katalon and Selenium ultimately comes down to your unique testing requirements and the level of technical expertise on your team. While Selenium is a more sophisticated and flexible tool that takes more technical expertise to use efficiently, Katalon offers an all-in-one solution that is simple to use and provides test case management.


A comprehensive test automation system, the Katalon Platform offers a wide range of functionalities and capabilities for automated testing.For testers looking for a powerful test automation software that is easy to use and has several integrations, Katalon is a wonderful option. Selenium, on the other hand, is better suited for customers that need sophisticated features like distributed testing, debugging tools, and integrated reporting.

Despite the fact that both of these automation test tools are excellent, Katalon performed somewhat better than Selenium in our evaluation.
