Katalon Reviews & Product Details

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 Review collected by and hosted on G2.com.

The low-code approach, ease of adoption, and ability to scale automation are the biggest strengths for me. Katalon supports multiple testing types in one platform and integrates well with CI/CD. KRE, reusable components and AI/self-healing capabilities also help make regression automation easier to manage at scale. Review collected by and hosted on G2.com.

Performance and stability with large regression suites could be improved. Licensing costs when scaling execution can also be a challenge, and I’d like to see further improvements in debugging and self-healing capabilities. Review collected by and hosted on G2.com.

All-in-One Solution, Low-Code & No-Code Automation, Pre-Built Test Framework, Rich Built-in Reports & Analytics, Easy CI/CD Integration, Built-in AI & Self-Healing Tests and Data-Driven Testing Review collected by and hosted on G2.com.

Performance Issues – Katalon Studio can be resource-intensive, leading to slow performance, especially with large test suites. Also Limited Flexibility Compared to Open-Source Tools – While it provides a codeless option, customization and complex scripting can sometimes be more restrictive than Selenium or Appium.

The facility to create scripts by recording actions through browsers, the ability to use variable data to execute numerous tests with different data, is the best automation tool I have used and still exploring their longest capabilities. Review collected by and hosted on G2.com.

The platform seems to use a lot of hardware resources. I'm on an 8GB laptop and it gets slow when I use the platform. Review collected by and hosted on G2.com.

Another thing Katalon has given users unpaid trial for long time now. Review collected by and hosted on G2.com.

I think katalon can be more efficient and fast. Review collected by and hosted on G2.com.

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 Review collected by and hosted on G2.com.

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 Review collected by and hosted on G2.com.

Katalon's built-in features, AI Assistance & easy integrations with JIRA and DevOps, to mention a few. Our coverage using Katalon has been much faster, close to 8 to 10x. Most importantly, the support from the team is very good. Review collected by and hosted on G2.com.

The only downside I see is the price being a little high, but the features and support outweigh it. Review collected by and hosted on G2.com.

I like the unified platform for web, API, mobile, and desktop automation. Its intuitive, easy-to-use interface, customizable scripting, detailed reporting, and seamless CI/CD integration make creating and running tests simpler. It reduces the overall automation effort while remaining flexible enough to handle complex test scenarios. Review collected by and hosted on G2.com.

Better performance, more reliable desktop automation, improved debugging, and enhanced handling of dynamic UI elements would make the platform even better. Review collected by and hosted on G2.com.

We have used Katalon mainly to automate our web and api tests to avoid long hours of regression testing manually in our test environments before a release and using testops as a centralised location for all our test cases it is great value at the moment as like i said we are able to release more software due to the time its saving us Review collected by and hosted on G2.com.

Nothing majorly to dislike - maybe just the fact that we have struggled with some Jira integration where certain fields do not pull through to testops Review collected by and hosted on G2.com.

API Script writing is easy. Can easily integrate API. Review collected by and hosted on G2.com.

Provide options to resize the screen. The screen is too busy Review collected by and hosted on G2.com.
