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 Apache JMeter is its popularity. It is the best open-source tool with all the features needed."
"Monetary benefits with Apache JMeter are notable since it doesn’t require a licensed version."
"Overall, I would rate Apache JMeter as eight to nine out of ten."
"This solution is easier to use than any other tool in the market; there is not even a requirement to learn a lot of scripting in order to use it."
"We find the ease of use and the reports and graphs available valuable."
"The ease of use is the solution's most valuable feature. Also, the ability to easily create test cases is also very good. It's easy to just ramp up on the solution."
"The most valuable features are the integration with Jenkins and the reporting."
"Apache JMeter is stable."
"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."
"The performance and reporting of this solution have been its most valuable features."
"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."
"We can scale."
"he initial deployment process is easy."
"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 like a centralized interface that allows us to increase the quality of our APIs."
 

Cons

"The only thing is the learning curve. It's high."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"Scalability is somewhat of an issue, which I would rate around five or six. For runs involving a thousand or more users, JMeter presents a problem because of memory and related issues."
"Until now, JMeter is not supporting most of the protocols."
"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."
"There is some work to be done with the integration."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"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."
"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 want the solution to be able to monitor Apache Kafka activity as well."
"We need some time to understand and configure the solution."
"It is very slow sometimes."
"I'd not sure if they have the same level of documentation for performance and security testing."
 

Pricing and Cost Advice

"The tool is open-source."
"The solution is open-source."
"Apache JMeter is a free tool."
"Since we are using an outsourced solution, it is not paid for by our company."
"No licensing is required as it is a free, open-source tool."
"Free"
"The solution is open source with no user fees or licenses."
"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"

"ReadyAPI Performance’s pricing is reasonable."
"We find the cost to be affordable."
