Documentation is good.
I appreciate the ease of using Postman, especially its desktop version, due to the features it offers such as cookie management and environment synchronization.
There is a lot of support available through forums and user groups, which has been sufficient for me.
 

Scalability Issues

Katalon Studio is cost-effective and scalable for small teams but less optimal for large-scale load testing.
Sentiment score
7.2
Postman is scalable for diverse teams, but performance issues and lacking features affect heavy use and expanded scalability.
It allows me to develop, run, and deploy test cases extensively.
Postman does not have database validation available, which affects its scalability.
This solution is scalable.
 

Stability Issues

Katalon Studio is stable for most users, but complex projects and updates can cause crashes and integration issues.
Sentiment score

Postman is rated highly for stability, with occasional latency or issues mainly related to large APIs and connection challenges.
It needs more stability when test cases are executed.

Room For Improvement

Katalon Studio faces scripting limitations, unreliable Object Spy, slow testing, stability issues, and lacks integration and support features.
Postman needs better integrations, UI simplification, enhanced automation, data-driven testing, improved reporting, authentication, and database connectivity.
Parallel execution is available, but not with the free version.
Providing clearer guidance during the trial period for certification and training modules would also help.
There is significant competition, so providing a good offer with extra features could be beneficial.
One of the primary challenges with Postman is handling authentication issues, especially relating to tokens and passwords.
If they can enhance it to have a database kind of validation like we have in ReadyAPI, it would be better.
Maybe Postman can be a good contender and replicate some features such as more scripting and control over API calls.

Functional automation features and the recording functionality saves time but the performance and script execution is slow
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.

Solution simplifies web service testing with impressive speed and accessibility
It is very easy for me to use and I highly prefer it compared to SoapUI and other products for performing its job. It is more handy and faster. It has impacted us very nicely. Postman is used for free by us. I'm not sure if there might be a paid version for multiple users. It is a very good product used for development. It is easy to install, as well as to learn, particularly for new users, even if they are not developers. I taught my business analyst to use it. I just showed them once, and it was easy for them to understand. For example, I gave them the URL and request format and asked them to test independently. They were able to use it on their own and do their testing as well. It was a good experience, especially for generally smart people, like those we usually hire in our company. It is pretty easy to explain, and learning it is not complex.
