Shashidhara Allalappa - PeerSpot reviewer
Extensive Protocol Support and Precise Reporting Elevate Testing, Though GUI Usability Needs Improvement
The GUI of Apache JMeter is not that user-friendly because we have many proxies, and we have to record through the proxy. With the limited SSL we have, we cannot use it for UI, which is a drawback. However, Apache JMeter is really good for REST APIs. I don't think there are any other areas other than the GUI that I would want improved about Apache JMeter; it is generally good and supports multiple protocols.
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.

Quotes from Members

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

Pros

"The most valuable feature of this solution is that it is free."
"It's a free tool."
"The reports and analysis tools are very good. They are the solution's most valuable features."
"I appreciate JMeter's simplicity and power for performance testing."
"The solution helps by detecting bottlenecks."
"It is an open-source tool that is easy to use. It can be easily integrated with multiple tools, including Selenium."
"It's a powerful tool that is open source."
"JMeter is a free tool with a large user population, which comes in handy because we have a vast knowledge base to tap into when needed. It's also easier to hire consultants who know JMeter."
"he initial deployment process is easy."
"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."
"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."
"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

"Its reporting could be improved. There should be a better visual representation. That would be helpful for easy consumption of the reports."
"In future releases, it would be helpful if there was an integration with ALM Octane."
"The reporting section of the solution can be better."
"Improving JMeter's sync time would be beneficial."
"One of the drawbacks of JMeter is that it can't handle a large amount of load, which forces us to switch to other tools when we need to load more than a 5,000 or 10,000 user load."
"Running JMeter in GUI mode uses a lot of memory, which means we need to switch to a non-GUI mode when using a heavy load."
"From an improvement perspective, consider a scenario where your application needs to retrieve data from PayPal and store it in an Excel file in an external network."
"JMeter should be more stable. Every time there is a new release coming up, a lot of its older functionalities or the new functionalities that are brought in are not very well-documented. It should be documented properly, and there should be proper use cases."
"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."
"The solution’s interface could be improved."
"I'd not sure if they have the same level of documentation for performance and security testing."
"I want the solution to be able to monitor Apache Kafka activity as well."
"It is very slow sometimes."
"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."

"This is an open-source solution, and there are no fees."
"Apache JMeter is a free open source solution and it is why we are using it."

"We use the open source version."
"ReadyAPI Performance’s pricing is reasonable."
