What is better for automation testing – Selenium or Katalon?

Selenium and Katalon are both strong automation testing tools, but the better choice depends on your project needs and experience level. Selenium is open-source, highly flexible, and widely used for web automation, making it ideal for teams needing customization and integration with frameworks. However, it requires programming knowledge. Katalon, built on top of Selenium and Appium, offers a user-friendly interface, built-in features, and faster test creation, which suits beginners or teams needing quick setup. For large, scalable, and customizable automation frameworks, Selenium is often preferred. For faster implementation, easier maintenance, and all-in-one testing capabilities, Katalon can be the better choice.
