The ease of starting automation with Katalon is amazing: during an internal course we were able to quickly make it work and have 10 users internally split worldwide script their first Web UI automated scenario with no technical issue or limitation like third party software install / library install / machine configuration...

The fact that a Docker image is provided for remote run with ease and all the capabilities which come with Katalon Platform are great compared to other tools: TestOps website to upload / centralize all tests results with screenshots and video records, visual testing simplified, etc...

Also Katalon does not stand idle and keeps innovating, bringing new features or product, and has both a very active and professional support in addition of a supportive forum community.

Last but not least Katalon still provides a free unlimited version of their studio, with less feature than paying version of course, but it's a clear advantage compared to competition where often only full version 30 days trial are proposed which can be complicated for demo / training / PoC etc...

Perfect for Web UI clearly, whereas not so great for Desktop App test automation...

I guess all this hard work to make Katalon such a great tool comes with a price, explaining why license prices increased significantly over the years and are now close to competition. Yet it is something to keep in mind that Katalon is not as affordable as it used to be.

Allows us to hide selenium complexity and make test automation scripting very easy, close to no code but keeping some dev-like abilities when needed.

Very easy to understand as compared to the other automation platforms out there. Has a wide array of options to choose from in terms to automation operations. Hardly had to look out for help guides in order to walk through my certification program. Was really a breeze!

None that I can point out. Had a great experience overall.

Helping me automate with just the UI and no-code approach, Katalon would be my go to tool going forward as a preferred choice.

One tool does it all! WebUI, API (SOAP/REST), Native, Mobile, parallel executions, multi-browser, Git interoperability, Eclipse IDE etc. Support is great too. I love that it supports all levels of users, from quick record/playback and keywords, to experienced developers that need everything. I've used Katalon every day for the past three years and it's head and shoulders over its competition... and I've been developing test automation for 33 years, so I know what I'm saying here!

Price and inability to have some users with the free license to start with, because we have paid license usage.

Test automation of (mostly) web applications. Having a tool that I can depend upon at the heart of our test automation framework makes my job as QA Automation Architect much easier.

Ease of use to get up and running quickly. Capable of great data-driven testing and limitless potential to get you through the complicated testing scenarios.

I have not found the auto-heal functionality to be very useful. The beauty is that it can also be disabled.

Regression testing for many customers. Complex testing necessary to fit the user experience.

The great thing about the Katalon platform is its wide range of features and it is so easy to learn. and it also supports CI/CD tools.

Some features are only accessible in paid version.

Katalon supports all types of testing like web, mobile, API, and Desktop so Katalon is an all-in-one package to work with. and because of active participants and a big community, getting help about any issue is so quick.

Simplicity, ease and convinence bundled with a plethora of features that has made testing and test orchestraion a cake walk. Scaling up is also pretty easy and fast

Nothing. Everything is perfect about katalon studio. I can talk in kength about the pros and pros of this fantastic tool that is helping the customers around the globe

Test automation and test orchestraion Integrated with a super platform testops that has made the test management really convenient. On top of it the katalon testops platform helps the PO/Managers to get the insights of their releases really afst

Katalon greatly reduces the the amount of time creating and maintaining test cases using recording and creation of test objects

We have no issues with katalon: our team enjoy using the tool

Katalon is allowing us to quickly create automation tests so we can reduce the amount of manual testing required

Combining Selenium, JavaScripts, Groovy, and has a great report system

Some missing Integration like AWS Codecommit

It has Framework ready to work, and there is no time wasting, updating your basic scripts, such as WebDriver,.....

Katalon has transformed from a simple Selenium/Appium wrapper into a unified, AI-driven Quality Management platform. The platform's recent evolution stands out for several key capabilities: TrueTest™ Autonomous Test Generation: Uses AI agents to analyze real user traffic and journey paths in production, automatically generating functional regression test scripts without requiring manual flow mapping.GPT-Powered Studio Assist: Integrates generative AI directly into Katalon Studio to generate custom Groovy code snippets from natural language, explain complex script failures, and auto-generate test data on the fly.Smart Self-Healing Selectors: Reduces test maintenance by using dynamic dual-locator algorithms and visual AI; if an object ID or XPath changes in a deployment, it automatically recovers during execution and suggests permanent locator updates.Unified Cross-Platform Engine: Executes tests across Web, Mobile (iOS/Android), REST/SOAP APIs, and Windows Desktop within a single unified script framework. Visual Testing AI: Catches layout shifts, pixel distortions, and responsive design breakages using integrated visual regression models directly in the execution pipeline.TestOps Quality Insights: Analyzes historical execution data to flag flaky tests automatically, predict release risks, and deliver root-cause failure analysis.

Bundled package with claude code support will be beneficial

Katalon solved the implementation, maintenance, organizing tests, reporting, Test Ops, parallel execution, cloud execution, parallel cloud execution, parallel mobile cloud execution, and cloud tunneling to execute private network-based applications.

Katalon is a very useful and intuitive application. it enables me to easily record various types of automated test cases such as Web, Mobile, API and Desktop. I have been mostly creating test cases for Web UI applications in our Telecoms environment. We have been heavily testing our customer Service Management tool (Which is web based) using Katalon.

We have an older Java based Customer service management and payments tool that we need to automate testing for. However so far we have been unable to use Katalon for this. We have to be searching for other applications to be used for this automated testing. It would be so great if Katalon would also support legacy Java User interface testing.
