Easy to deploy and not hard to learn, but keeps on crashing on Linux and is a bit slow
Pros and Cons
- "It has been good so far for API testing on Mac. It is not that hard to learn and use. There is so much support out there, so if anyone wants to start using it, there is enough help."
- "Currently, I'm the only one who can use it because I have a Mac. It is giving a hard time to my team members who are on Linux. My team members are using Linux, and Katalon doesn't support Linux very well. It keeps on crashing. It crashes and shuts down almost every time they save their work, so they are not able to use it. It should have good support for Linux. We don't know what the problem is. If the Katalon team can pick up this issue, it will be very helpful."

Professional Services Manager at a non-profit with 201-500 employees
Good testing framework with a straightforward setup but needs more features
Pros and Cons
- "The initial setup is pretty straightforward and easy enough to complete."
- "It seems to lack a few requirements that a typical customer would want. Compared to other solutions, this product is lacking."
What is our primary use case?
We primarily use the solution according to customer requests. We don't use it for a specific feature; we tend to use it when and if we are requested to. The client dictates that on their end. It's largely used as an automation testing tool. That's how it is meant to be used.
What is most valuable?
The solution has very good integration capabilities overall.
The client has an extremely stable testing framework, and therefore they rely on Katalon to get the results. The reporting is very good.
The initial setup is pretty straightforward and easy enough to complete.
The stability, overall, seems to be reliable.
We haven't found the scalability to be lacking.
What needs improvement?
The solution could always add more features. It seems to lack a few requirements that a typical customer would want. Compared to other solutions, this product is lacking.
I'd like the integration with Jira to be a bit better.
The pricing could be slightly improved.
For how long have I used the solution?
I've been using the solution for about a year at this point. It hasn't been that long. We tend to switch back and forth, between solutions. We tend to switch month to month.
What do I think about the stability of the solution?
I haven't come across any stability issues. Our clients haven't complained. It's pretty much big and glitch-free. It does not crash or freeze. Our customers have found it to be reliable.
What do I think about the scalability of the solution?
We haven't found any limitations with the scalability. Our clients haven't hit any barriers as of yet. It's my understanding that the solution can scale.
How are customer service and technical support?
I've never been in touch with technical support in the past. Therefore, I can't speak to how easy it is to get in touch with them, or how knowledgeable or responsive they are. Unfortunately, I have no insights to share.
Our team often Googles questions and can find answers online if they need to.
How was the initial setup?
We did not find the initial setup to be overly complex or difficult. it was very straightforward. It was simple.
We have a team that can Google questions and find information online pretty easily if there is any maintenance that needs to be handled. We tend to handle the maintenance aspect for our clients.
What's my experience with pricing, setup cost, and licensing?
It's my understanding that the pricing could be improved upon. I cannot recall the exact pricing. I cannot speak to the cost or licensing terms. We're just basically maintaining the solution for our clients.
What other advice do I have?
We are just end-users and use it according to our client's requirements. We don't have a specific business relationship with Katalon.
Some customers use ALM, and we use Jira, due to the lower price. These help us with project management aspects. This solution isn't well known, as it might be in other countries.
This solution is very useful for companies, such as banks or insurance organizations, that need something that can be used for commercial purposes. It's a good solution for enterprise-level companies.
I'd rate the solution at a seven out of ten. It's okay, however, if it offered more features to its customer base, it would be much better.

Software QA Test Engineer at a tech services company with 51-200 employees
Good reporting as well as integration with Jenkins and Slack, but it crashes often
Pros and Cons
- "The most important feature is the Jenkins integration; it is pretty straight forward and allows us to run nightly builds."
- "It would be helpful to have an automatic save feature."
What is our primary use case?
We evaluated Katalon Studio along with Postman and SoapUI to be part of our testing framework. We used it mainly for microservices, API automation, and testing API endpoints. We click one button to have it run all of the tests and generate a report.
How has it helped my organization?
Katalon Studio is useful because it helped us to generate reports to see which test cases passed versus which ones failed. It gives a good graphical representation of the results.
What is most valuable?
The most important feature is the Jenkins integration; it is pretty straight forward and allows us to run nightly builds.
The integration with Slack is very helpful.
The Katalon Analytical Studio, which is directly integrated, offers better reporting capabilities, which is a good feature.
What needs improvement?
We found that Katalon Studio crashes a lot of the time and it would be very good if it were more stable. When it crashes, the tests are not always saved and this means that you have to start again from scratch. It would be helpful to have an automatic save feature.
For how long have I used the solution?
We used Katalon Studio for about two months while we were evaluating different products.
What do I think about the stability of the solution?
This solution crashes often and stability is something that needs improvement.
I would rate the stability a six and a half out of ten.
What do I think about the scalability of the solution?
Scalability depends on the scope of the project. It is not meant for load testing. However, if it can be integrated then you would see that it's more scalable in that aspect. Because it is just for API endpoint testing, it is not as scalable as one would assume. Again, it is for endpoint testing as opposed to load testing.
We had a team of four or five people who were using this product. They are test engineers with similar roles.
How are customer service and technical support?
It is a growing community. There are documents available but I would say that the community is pretty small as compared to what Postman has.
Which solution did I use previously and why did I switch?
Prior to this solution, we were using TestNG. It is more about writing automation code as opposed to using an automation tool. Using it means that you have to write a lot of code. Code snippets will do for some testing but if you want to do regression testing then there is a lot more to do. One of the reasons that we implemented Postman, and evaluated Katalon Studio, was to get away from writing code and using something more stable.
How was the initial setup?
The initial setup is quite straightforward.
We deploy per release, where every two weeks we deploy a new release.
Our implementation strategy is to create the test case first, then to create a test suite in the object repository. We can add all of the endpoints, and the calls for the endpoints. We run the tests through the suites, which will test all of the test cases. It is then run with the Jenkins integration and Slack integration to get the results, and what has passed or failed will be clear.
What about the implementation team?
The implementation is straightforward if you are using it from the local machine. You can download it directly through the provider interface.
If you are running it through the Jenkins you will require a plugin to be downloaded. Jenkins supports plugins that include the Katalon plugin, and once downloaded, you enter your code into the repository and run it from there.
What's my experience with pricing, setup cost, and licensing?
We were using the free version of this tool.
Which other solutions did I evaluate?
We evaluated Postman and SoapUI along with Katalon Studio. Ultimately, we chose Postman because it has been in the market for a while, it has good open-source documentation and has a more active community. In general, people trust it.
What other advice do I have?
Products such as this one are a byproduct of artificial intelligence. It comes up with very nice code snippets that we can use, and it is good to see the industry moving forward in this aspect. The future is AI and Katalon is a part of that.
When it comes to testing RESTful APIs, this is a good solution but in the alternative, Postman is out there. That is the one that we ultimately chose to implement.
I would rate this solution a seven out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

Test Lead at a financial services firm with 1,001-5,000 employees
Good end-to-end UA, Web,API, and mobile app testing capability
Pros and Cons
- "The basic framework and project organization is very good."
- "We have had some issues when it comes to stability, which is something that needs to be improved."
What is our primary use case?
We primarily use this solution for user acceptance testing, web testing, regression testing, and mobile app testing.
What is most valuable?
The most valuable feature is the capability of doing end-to-end testing for both web and mobile apps.
The basic framework and project organization is very good.
Data design testing capabilities are useful.
What needs improvement?
The maintenance of the tools can be improved.
We have had some issues when it comes to stability i.e when project has lot of items in workspace, which is something that needs to be improved.
For how long have I used the solution?
I have been using Katalon Studio for just under two years.
What do I think about the stability of the solution?
At times, Katalon is a little bit non-stable i.e When a project has lot of items in workspace, it takes a while to save . We have had a couple of issues related to instability for more complex models, but we are hoping that it will get better. Because of these issues, we are not able to integrate this solution into our platform.
What do I think about the scalability of the solution?
The scalability is okay for our immediate purposes. We have a maximum of ten users who are all test engineers.
How are customer service and technical support?
We did have a couple of questions for technical support but we did not have direct interaction with them. Instead, we asked them through the web community forums, and some of them were answered.
It was a difficult problem so that may be why not all of our questions were answered. Also, you don't always get reliable answers from the community. For example, we followed some free advice to help with the implementation and it was not good for that purpose.
Which solution did I use previously and why did I switch?
Prior to Katalon Studio, we were using UFT for our testing. We switched because Katalon is free and doesn't cost any money. It works in the meantime, and they have the capabilities that we need. The cost was definitely a factor.
How was the initial setup?
The initial setup is really simple, which is one of the good things about this product.
It was really easy to implement and use. I look for information online from Katalon before we started our testing.
What about the implementation team?
We completed the implementation using our in-house team.
It takes two or three people to deploy and maintain this solution.
What's my experience with pricing, setup cost, and licensing?
There is a free version of the tool to use and support is available through the community forums, but there is a licensed version as well.
Which other solutions did I evaluate?
We did not evaluate other options. We needed certain capabilities and we found Katalon to be acceptable.
What other advice do I have?
It is a good product. I would recommend it because they are promoting that they will update it for free, for life. We have had issues with stability but it might be better with the licensed version.
I would rate this solution a seven out of ten.
Which deployment model are you using for this solution?
On-premises

It scales well, supporting the execution of large test suites
What is most valuable?
- Katalon Studio provides the team much flexibility to adapt to various situations to address a problem appropriately. There are certain test cases that can only be tested manually, but Katalon allows the team to automate as many test cases as possible.
- The “Debug from here” feature reduces the debugging time considerably.
- It produces detailed and useful logs, helping the team to detect a defect’s root causes easily.
- It scales well, supporting the execution of large test suites.
- It can be used to verify various issues, ranging from minor errors like typos to performance and stability problems of the system.
How has it helped my organization?
Before using Katalon Studio, we spent weeks to verify all test cases manually for every major build. Now, we need only several days to fully perform regression testing, reducing the time to market greatly.
What needs improvement?
While the web testing is great, we expect more from the API testing.
For how long have I used the solution?
More than six months.
What was my experience with deployment of the solution?
No. It's very easy to deploy.
What do I think about the stability of the solution?
Rarely.
What do I think about the scalability of the solution?
Not yet.
How are customer service and technical support?
Customer Service:
They provide very good customer service.
Technical Support:Excellent, since they promptly respond to our requests.
Which solution did I use previously and why did I switch?
Robot Framework. However, it required more technical involvement, so the dev team needed to join and spent time setting up before our QA could join.
What about the implementation team?
In-house.
What was our ROI?
After several years using Katalon Studio, the team now already automates more than 20% of the test cases, saving much of the verification time as well as exceeding the target set when starting the test automation effort.
What's my experience with pricing, setup cost, and licensing?
The tool has been completely free until now.
Which other solutions did I evaluate?
TestComplete and UFT. They're all costly.
