Open-source and flexible but needs client-side scripting
It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS. Also, the APIs tested with SoapUI can be directly used, avoiding the need to create collections like in Postman. The client-side scripting, if incorporated, would provide a complete solution for performance tests. It can handle user distribution and transaction throughput distribution effectively.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The performance and reporting of this solution have been its most valuable features."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"It stores good reports, as in, improved reports if compared with the SoapUI. It also has in-built security. You just need to switch and check the security testing. My team has never used it, but I know ReadyAPI provides those facilities as well."
"It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS."
"We find the product to be scalable."
"It is a very good and handy product, there are so many features, and it is getting more popular day by day."
"ReadyAPI automation can help us validate the functionality of most web services, allowing us to find out the exact number of defects before deployment to the user interface."

Cons

"I'd not sure if they have the same level of documentation for performance and security testing."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"This solution could be improved by offering artificial AI testing in addition to API testing. For example, we would like to have machine learning testing because when test applications, manual work could be completed automatically using this functionality."
"I'm not sure if they have the same level of documentation for performance and security testing."
"It is very slow sometimes."
"This is an area for improvement with the tool. We unnecessarily use JMeter for some website testing, which we would like to avoid by introducing this tool for API and load testing because it provides load testing features."
"It is very slow sometimes. If they could improve its performance, it would be really great for the users."
"I want the solution to be able to monitor Apache Kafka activity as well."
"The solution could improve by increasing the Gbps speeds and by having better support for storage."
"The solution could improve by increasing the Gbps speeds and by having better support for storage."
