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

"We had some challenges testing HTTP/2 APIs, which are becoming more prevalent with advancements like 5G. So, we added another plugin to help with HTTP/2 API load testing. Apache JMeter, with additional plugins, now supports HTTP/2, which is critical as everyone moves from HTTP/1 to HTTP/2."
"The solution has good transition controllers and distributed testing."
"The most valuable features are the ability to capture the entire traffic of particular pages and the proper readability of entire pages and entire APIs."
"It's open source, so I like that about the product. And there's a lot of community support for it."
"API testing, Database Testing, and MQ testing can be done with ease."
"The most valuable feature in JMeter is the Thread Group, which helps us to see whether the performance is good."
"The most valuable feature for us is the available information on the forums and to be able to discuss and get answers from the people that are involved in using this tool."
"We like that Apache JMeter has different features and different plugins and that they are free of charge."
"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 can scale."
"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."
"he initial deployment process is easy."
"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."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"We find the product to be scalable."
 

Cons

"I sometimes found the documentation to be not as explanatory as I would've liked it. In the cases that I can think of, I was looking for a rather hand-holding approach with Step A, B, and C, but then I realized that with a product that is open source like this, you can't do handholding. That is because there are so many different uses and different unique environments and setups for it, but I remember thinking a few times that if they only just said this."
"JMeter's reporting is extremely rudimentary. The fundamental reporting mechanisms need to be drastically improved. It doesn't utilize an automatic session management mechanism or methods other tools use like parsing cookies and variables. Everything needs to be done manually. There's no automation."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"The tool needs to have a better Graphical User Interface. Many of the solution's features are difficult to understand due to the complex user interface and user experience. The product needs to add plugins. It should also work on the integration with external partners like IDE and API gateways."
"Apache JMeter may have difficulty recognizing dynamic objects in some critical cases, which can lead to challenges in terms of object identification."
"The user interface is a little bit tricky."
"To the best of my knowledge, the documentation could be improved. It should be enhanced to better support newcomers. Currently, only people with some experience can easily understand the content. Including more sample programs, applications, and use cases would help many more people adapt to using the solution."
"If the solution was GUI based, I believe that it would be more versatile."
"I'd not sure if they have the same level of documentation for performance and security testing."
"It is very slow sometimes."
"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 want the solution to be able to monitor Apache Kafka activity as well."
"The solution’s interface could be improved."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"We need some time to understand and configure the solution."
"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."
 

Pricing and Cost Advice

"The solution is open source."
"This is an open-source solution, so there are no licensing costs involved."
"The product has reasonable pricing."
"Free"
"Since it's free, there's no need for extensive support or improvements in pricing."
"We are using the free version."
"Since we are using an outsourced solution, it is not paid for by our company."
"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"
"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."
