Katalon Studio could improve by making test maintenance easier for very large projects, especially when applications undergo frequent UI changes. It would help if Katalon Studio handled large test suites more efficiently as projects grow. Additionally, advanced customization sometimes feels limited compared to fully code-based frameworks, and an additional feature such as smart locator management would be beneficial.
I feel nothing needs improvement for Katalon Studio, as it is already the best in the industry, providing the best enhancement for users. Katalon Studio is already top-notch with no need to improve.

One needed improvement is that if I run it one time, it works, but if I run it continuously, the application gets stuck. If I run the application 15 to 20 times, it may get stuck. I take off one point because of the slowness.
Based on my experience with Katalon Studio, improvements are needed, particularly regarding desktop application recording and playback, which should be more flexible and not limited to relying solely on .exe files installed on the system. We've encountered issues when connecting to remote machines where applications are installed, making it necessary for the tool to accommodate testing in such cases. This flexibility is crucial for service providers who may not have the option to onboard clients directly at their locations. Additionally, there is a need for improvements in mobile application automation compared to other applications available in the market.

I have noticed a little lag while loading applications during my automation process with Katalon Studio, and I'm not sure if that is due to the free user restrictions, but I think this lag in application loading can be improved. Katalon Studio sometimes restarts during automation, and as mentioned earlier, the app experiences lag, so those are the main areas that need improvement.
The pricing could be improved. Offering a discount on Katalon Studio licenses could encourage more users. There is significant competition, so providing a good offer with extra features could be beneficial.

Extending the certification validity, especially after the trial period, would be beneficial. Providing clearer guidance during the trial period for certification and training modules would also help. It would allow users to build expertise and promote the product effectively.
I would like Katalon Studio to develop manual test case generation using AI capabilities, as other tools like those using OpenAI are already doing this. Also, enhancing its test management aspects and improving support levels with translators for non-English speakers would be beneficial.
It should be faster while executing, and there are some defects, like choosing the new device with the test case. Parallel execution is available, but not with the free version. The videos or training videos are not providing proper information on setup, and it should give more insights so everyone can understand.
I would like to see improvements in how Katalon Studio works with iOS applications, especially with React Native applications. The speed is very slow. It takes time. Katalon Studio also takes my laptop memory, and execution becomes slow for the script. There are parallel execution options. I'm sure their online cloud version must be very fast, but as a service-based company, we are under NDA with our clients and can't run their code on our servers. I would like to see iOS improve and see a more capable recording feature. Katalon Studio has released an AI version, and I have a demo scheduled to see the new features.

Test report generation must be improved. It doesn’t fetch the right data. Even if we provide the proper screenshots, some are not fetched properly. HTML and PDF work fine. Sometimes, the client needs the report in Excel format. So, we skip the images because they are not properly implemented in Excel. Most clients know it. During parallel execution, some reports are randomly switched. We perform standalone switching to avoid such scenarios. The tool would be better if it improves object repository handling, Excel properties, serial execution, report generation, and scenario preparation.
Speaking of the improvement required in Katalon Studio, I can say that in my company, we struggle a lot with iOS automation. For iOS apps, in my company, we struggle a lot since we set it all up on Mac, an area that can be improved. If Katalon Studio allows for more integrations with other test management and project management tools, it would be great since, right now, its integration capabilities are very limited.
The product’s regression testing time could be reduced. The dashboards also take too much time to load. Additionally, its licenses are expensive. We have to purchase two licenses, including an enterprise license and a KRE license.
The product is comparatively slow. It is very slow when calling a test case within another test case and searching for it. The product is slow in the test case and execution. The product should be made more smooth and speedy.
The tool's maintenance is very difficult since they do not follow call by value or call by reference. Due to this, any change happening is not reflected throughout all the test cases. There are some issues with data parameterization as well.

Katalon Studio's support and service need to improve. They reply late and do not provide clear guidance, or a clear transition plan. The solution can be further improved with better loading time. In future releases, I would like to see the feature offered by their competitor included in Katalon. The competitors have image testing that captures a certain object on our website. Katalon would benefit by adding this feature.
Katalon Studio could improve having visual testing, but I think they're launching that feature very soon. We would like to see an increase in the usage of AI.
Katalon lacks integration ability with other software, including integrating other languages like .NET and PHP. I've also had issues with new releases as the system often crashes and the previous version is no longer supported on a particular feature. More testing needs to be carried out before new versions are released. I'd like to be able to export our test system to any other product. This is currently not possible. Finally, the product only supports XPath and not CSS. CSS is faster than XPath and most companies want to use it. There are a lot of solutions on the market and if an end-user has too many problems with a product, they will jump to a new one.

I've seen that our clients are not truly aware of the power behind Katalon. Many of the clients are now ready for the traditional Selenium, perhaps a more friendly layer like Cucumber or SpecFlow. But I think they will understand if we start doing automation with Katalon and they would be much more interested. The automation developers are starting to have really high demand and the salaries have increased, so with Katalon they might be interested in two things - the velocity of testing plus bringing manual testing to the automation world.

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. It is a bit slow. The other tools on my Mac are not slow, but Katalon is slow.

It would be helpful if we could develop from scripts in other languages. For example Python. It would be more convenient than working with Jira and Java. For some of my colleagues who don't have the knowledge in the development, it is easier to work with Python rather than with Java. After two years of using this solution for free, we were limited in the features that we could use and had to start to pay for them. Now, we are having difficulties in using it and had to limit our automation experts to the features that Katalon allows us to use for free. It was free access and they claimed that it would be free for all time. I would like to see it integrate other tools other than Jira, and to have support in other development languages would be helpful.
There is not much support offered for the free version, which is something that could be improved. Support for more frameworks would be a really good addition to this tool
The free version of the solution is not user friendly at all. The solution's most valuable aspect is related to the record and playback. However, they need to improve the record and playback facility. TestComplete and UFT both have a much better record and playback functionality in comparison. It's one of the main reasons why I have, for example, inline tools, like UFT 5.0. They need to improve their object repository. The solution isn't as mature as TestComlete or UFT. Although they are continuously writing more functionalities, this is one area they really need to improve in. Technical support needs to be improved upon.

My recently-updated Katalon studio version hangs a lot and is not a stable version. The support system should be improved in many areas such as Katalon Studio forums and the Katalon community page, where developer responses take a lot of time to reply to user questions. Actually support response time is more than expected.
The browsing is messy. The solution tends to rush the tests on multiple processes. That doesn't work in most cases. They need to write a different script for the same test case on the cloud and another script to run the test on Firefox, for example. Also, in terms of reporting, in the documentation, it's mentioned that Katalon takes screenshots if the test case fails. But not on all test cases. I need to take screenshots manually. Often, running parallel test cases at the same time doesn't work. If it launches the first test case and it tries to launch the second test case at the same time, for example, the first test case will finish but the second will not stop. A lot of people are talking about this issue on the forums. The application is prone to freezing when it loads. Katalon doesn't support testing of hybrid applications. It's a limitation.

At the moment, this solution only works for web-based products. It's sort of like a Selenium wrapper, which is quite well done. The Object Spy is rather frustrating to work with, so I tend not to use it. Instead, I just go and look at the objects in the HTML code, in Chrome for example. A more user-friendly Object Spy would be an improvement. I would like to see the extension to other GUIs such as Windows and SAP.
Katalon Studio is a regression testing tool that enables you to go low-code, boost productivity, and ease scalability. It is suitable for all platforms and operating systems, regardless of application complexity.
