Katalon is recognized as a March 2019 and March 2020 Gartner Peer Insights Customers’ Choice for Software Test Automation.[3] [4]


Katalon Studio provides a dual interchangeable interface for creating test cases: a manual view for the less technical users and a script view gearing toward experienced testers to author automation tests with syntax highlight and intelligent code completion.[5]

Katalon Studio follows the Page Object Model pattern.[6] GUI elements on web, mobile, and desktop apps can be captured using the recording utility and stored into the Object Repository, which is accessible and reusable across different test cases.

Test cases can be structured using test suites with environment variables. Test execution can be parameterized and parallelized using profiles.

Remote execution in Katalon Studio can be triggered by CI systems via Docker container or command line interface (CLI).[7]

From version 7.4.0, users are able to execute test cases from Selenium projects,[8] along with the previous migration from TestNG and JUnit to Katalon Studio.

In version 7.8, users can save team effort while debugging with smart troubleshooting approaches offered via highlight features: Time Capsule,[9] Browser-based Video Recorder,[10] Self-healing[11] and Test Failure Snapshots.[12]


The test automation framework provided within Katalon Studio was developed with the keyword-driven approach as the primary test authoring method with data-driven functionality for test execution.[5]

The user interface is a complete integrated development environment (IDE) implemented on Eclipse rich client platform (RCP).[5]

The keyword libraries are a composition of common actions for web, API, and mobile testings. External libraries written in Java can be imported into a project to be used as native functions.[13]

The main programming language used in Katalon Studio are Groovy and Java.[14][15] Katalon Studio supports cross-environment test executions based on Selenium and Appium.[16]

Katalon Studio started out as Freeware. In October 2019, Katalon introduced a new product set with proprietary licenses in its seventh release.[26] The new products and licenses include, including Katalon Studio (Free), Katalon Studio Enterprise, and Katalon Runtime Engine, so that teams and projects of various complexities can have a flexible allocation on budget, licensing, and scalability.[27]

Relevant productsEdit

Katalon TestOpsEdit

Katalon TestOps is a web-based application that provides visualized test data and execution results through charts, graphs, and reports. Its key features include execution grid, advanced reports, monitoring and alert, and AI analytics. Katalon TestOps can be integrated with Jira and other CI/CD tools.[28]

Katalon TestOps was originally released as Katalon Analytics in November 2017. In October 2019, Katalon officially changed the name to Katalon TestOps.[29] It is currently available in beta version.

Katalon RecorderEdit

Katalon Recorder is a browser add-on for recording user's actions in web applications and generating test scripts. Katalon Recorder supports both Chrome[30] and Firefox.[31] Katalon Recorder functions in the same way as Katalon Studio's recording utility, but it can also execute test steps and export test scripts in many languages such as C#, Java, and Python.


Katalium is a framework[32] that provides a blueprint for test automation projects based on Selenium and TestNG. The framework is built to help users who still need to work with TestNG and Selenium to quickly set up test cases.[33]

Katalium Server[34] is a component of the Katalium framework. It is a set of enhancements to improve the user experience with Selenium Grid. Katalium Server can be run as a Standalone (single) server in development mode.

Both Katalium Framework[35] and Katalium Server[36] are made open-source.

Katalon StoreEdit

Katalon Store serves as a platform for testers and developers to install add-on products (or ‘plugins’) and add more features and optimize test automation strategies in Katalon Studio. Users can install, manage, rate, and write reviews for plugins.[37]

In Katalon Store, plugins are made available in 3 main categories: Integration, Custom Keywords, and Utilities. Katalon Store also allows users to build and submit their own plugins.[38]


Katalon Studio can be integrated with other software products,[39] including:
