But is it really that good? Well, that depends on the context and your purpose.
In this review, we’ll fill you in on Katalon – the good, the bad, and the “why didn’t anyone warn me about this” parts. Let’s begin.
Katalon Studio is a cross-platform test automation tool that was released in 2015. It was developed by Katalon LLC (previously a subsidiary of KMS Technology before the spin-off as an independent entity in 2019). Briefly, it’s an all-in-one testing platform that tries to solve the problems of test automation.
So what does Katalon solve? In a nutshell, it tries to bridge the middle ground between script-based testing for techies and codeless testing for newbies. It tests web, API, mobile, and desktop applications all in one environment.
The platform has expanded beyond just Katalon Studio to include Katalon TestOps (for orchestration and analysis of tests) and Katalon Runtime Engine (for CI/CD integration and command-line execution). In addition, it includes Visual Testing, and recently, AI-powered capabilities for test generation and maintenance.
Katalon offers both record-and-playback as well as script editing capabilities. This is what it generally does:
The tool is built on top of open-source tools like Selenium and Appium. It tries to wrap them in a more user-friendly interface and offers additional features. However, we see comments like this about Katalon Studio from time to time:
"I personally really dislike Katalon. It's a decent tool if you have no coding experience, but it scales horribly and is incredibly hand-holdy. You'll find yourself frustrated more often than not, and end up having to code anyway."
So it seems there are two sides of the coin. Let’s decipher each one for you.
Katalon has carved out a unique position in the market. It’s not just for the coding wizards or exclusively for those allergic to code. Its user base spans across:
According to Katalon’s website, they serve over 65,000 enterprises and teams, including some big names like FPT Software, Sony, Panasonic, and BBVA. The platform claims to have more than 1 million users worldwide.
Let’s break down Katalon’s features one by one.
Test creation technique is probably Katalon’s strongest selling point. It is easier for people in your team with almost no technical expertise, and this is all you need to do:
Technical individuals have access to a script mode wherein they can test in Groovy or Java with all Selenium WebDriver functions available.
A shout-out to the object repository. It holds all of the things that your tests are dealing with in one location. So maintenance isn’t as painful when your developers decide to swap that button ID at 4:59 PM on a Friday.
Later in 2023, Katalon started deploying AI capabilities for test automation and auto-healing tests. While promising, these are currently in their infancy and community feedback is mixed.
There are solutions that push your efficiency even further with AI-driven automation. Katalon helps you in structuring test cases, but the solution we give you will also generate them intelligently. You will need no manual effort in the process.
That solution is aqua cloud. Aqua’s AI-powered test case generation takes your efficiency to the next level. All you need to create a complete test case is a requirement (which can also be generated in 2 seconds with aqua). With 2 clicks, you create test cases automatically. Compared to manual test case creation, it means 98% more efficiency. You can take it one step further with aqua – one more click and you have thousands of rows of synthetic test data ready too. So, requirements, test cases, and test data – all within 3 clicks. Furthermore, you get customisable reports, one-click bug tracking, seamless integrations (Jira, Azure DevOps, much more) within a centralised management.
Don’t experiment; go with a proven, 100% AI-powered solution
Katalon lets you run tests across multiple browsers (Chrome, Firefox, Edge, Safari) and mobile platforms (Android, iOS). You can execute tests:
The execution profiles feature is particularly useful, allowing you to maintain different configuration sets for various environments (dev, staging, production).
However, there are complaints regarding the test execution too:
"It's one step forward, two steps back with these apps - I'll record a test for one of our sites (i.e., user registration), and it'll run well, but then fail on a random element the next time."
“The smoke test suite of one of our applications is taking hours to run for all the markets. It is implemented using Katalon. This frustrates me a lot because often it is faster to just do manual testing."
Mobile testing in Katalon has also received criticism for being less robust than web testing. Setting up mobile test environments is particularly challenging for beginners.
On paper, Katalon’s integration list is impressive:
In practice, these integrations often require significant configuration and don’t always work seamlessly. The Jira integration, while functional, is also complex and has occasional sync issues.
Katalon TestOps offers analytics and reporting features, including:
The reports are visually appealing and can be exported in various formats (HTML, PDF, Excel). However, the more advanced analytics require a higher-tier subscription, and some users feel the basic reporting could be more comprehensive.
A review on TrustRadius mentioned:
“The reporting is good but not great. We often need to export data and create our custom reports for management presentations.”
This is where things get interesting. Katalon’s support structure varies dramatically depending on your subscription tier:
The community forums are active, but the community is small. Documentation is comprehensive but sometimes lags behind new features.
Katalon’s pricing model has evolved significantly over the years. It has transitioned from a completely free tool to a tiered subscription model. As of 2025, Katalon offers:
This pricing is controversial in the testing community. Many managers question whether this cost is worth it. Not specifically about Katalon Studio, low-code test automation tools have a reputation for being a waste of money, and we can see it from Reddit:
"Katalon I have heard of but avoided because they had their own way of working that really tied you to the product and I had enough of that when I worked with QTP/UFT from HP/MicroFocus."
"Because they lure in the gullible (i.e. managers) with their promises of easy automation but spectacularly fail to deliver. The poor testers then have to pick up the pieces and try and make it work."
After sifting through countless reviews, forum posts, and our testing experience, here’s a balanced view of Katalon’s strengths and limitations:
Pros:
Cons:
Of course, it’s not up to us to make a decision, and ultimately, it’s your choice. However, it seems that some of the users have already made their decisions and stated them publicly. Like this one, on Reddit put it:
“The best practice with Katalon is to uninstall it and use another tool.”
So even as a dedicated no-code automation solution, people suggest using Playright, Selenium, and other solutions instead of Katalon.
If Katalon doesn’t seem like the perfect fit, here are some alternatives worth considering:
Automate 200% of your test management efforts with AI

The right choice depends on several factors. You need to consider your team’s technical skills, budget, and specific testing needs. You can use multiple tools and integrate them too, for example, aqua cloud + Selenium might work best for you.
After spending many hours researching Katalon and gathering real user experiences, here’s our take: Katalon occupies an interesting middle ground in the test automation. It’s neither the simplest tool for complete beginners nor the most powerful for automation experts.
Katalon shines brightest when:
However, it will disappoint if:
The truth is, there’s no perfect testing tool – just the right tool for your specific context. So if you are in search of a test management solution that is not solely tied to automation (flawed automation by the way), then your selection should be aqua cloud instead of Katalon.
Yes, Katalon is a low-code test automation tool. It allows users to create automated tests using a record-and-playback feature and a visual test design interface. However, it also supports scripting in Groovy and Java for advanced users who need more flexibility.
Yes, Katalon introduced AI-powered test automation and self-healing capabilities in 2023. However, these features are still evolving, with mixed feedback from the community. If you’re looking for a more mature and impactful AI-driven approach you need aqua cloud. With 98% time savings in test case generation, AI-powered test data creation, and smart automation, aqua cloud delivers faster, more reliable test management at scale.
Yes, Katalon is a solid choice for API testing. It supports REST, SOAP, and GraphQL requests. It also offers automated assertions with request chaining. Its built-in scripting and integration with CI/CD pipelines make it useful for both beginners and advanced users. However, it is not as powerful as dedicated API testing tools when it comes to large-scale performance testing:
Katalon is a low-code test automation tool, meaning you can create and execute tests with minimal coding. It offers a record-and-playback feature and a keyword-driven approach. So Katalon makes it accessible for testers with little to no programming experience. However, for advanced test customisation, users can write scripts in Groovy or Java, using Selenium WebDriver functions.
JMeter is for performance testing. It pushes systems to their limits—load, stress, scalability. Numbers, graphs, response times.
Katalon is for automation. It handles UI, API, and functional testing. Record, script, run. Low-code, AI-powered, easy for teams.
JMeter breaks things. Katalon checks if they work. Different goals, different tools.
