Has monitoring capabilities integrated into it to see the performance of components while the test is in the running phase
NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. NetStorm gives the feasibility of generating load with multiple load arrival models helping components to be tested based on its usage. NetStorm has monitoring capabilities integrated into it to see the performance of components while the test is in the running phase. One more great functionality is the ability to control the load runtime by increasing or decreasing the virtual users or pausing the users to keep on repeating the transactions without exiting.
Mahendra Andhale - PeerSpot reviewer
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.

Pros

"This tool helps to focus on real-time transactions that occur at a very high rate."
"NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. NetStorm gives the feasibility of generating load with multiple load arrival models helping components to be tested based on its usage."
"Designs dynamic scripts and scenarios, as per our requirements, which is one the most important feature available in NetStorm. It helps us to do performance testing of our application in a periodic way."
"The performance and reporting of this solution have been its most valuable features."
"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."
"he initial deployment process is easy."
"We find the product to be scalable."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"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."
"We can scale."
 

Cons

"In the next release, we are looking for a JS instrumentation feature that would be helpful in identifying client-side issues at an early stage, or during testing."
"The user interface had to be improved for the product. Its user interface should be made simple and easy to customize as per user needs."
"Need to add or support some more APIs in the Script Manager window."
"I want the solution to be able to monitor Apache Kafka activity as well."
"It is very slow sometimes."
"The solution’s interface could be improved."
"I'd not sure if they have the same level of documentation for performance and security testing."
"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."
"We need some time to understand and configure the solution."
"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."
 

Pricing and Cost Advice

"NetStorm is priced well when compared to many well-known tools."
"This solution operates on a licence basis and the usage and cost varies according to the use case. It is more expensive if you include access to the learning center. On average it costs approximately 800 Euros."
"ReadyAPI Performance’s pricing is reasonable."
"We find the cost to be affordable."
