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 features that I appreciate are quite basic. It is easy to ramp up the threads and start calling the application. A lot of connectors can already be found within Apache JMeter, but we are not using the entire set because the integration between the customers and platform is based on HTTP. We are just going to produce lots of HTTP sequences."
"Apache JMeter is stable."
"The most valuable feature of this solution is being able to launch many requests and scheduling simulating human interactions with the application."
"The most valuable features of Apache JMeter include SCTP sampler, throughput controllers, stepping up thread group, parallel controller, timers, and the ability to use gRPC protocol."
"The new version of the solution is stable."
"The most valuable feature of this solution is that it is free."
"Overall, I would rate Apache JMeter as eight to nine out of ten."
"To me, what's most valuable in Apache JMeter is that it's a lightweight tool for application testing. It's the best load-testing tool for my company because Apache JMeter simulates your application during testing. Apache JMeter also creates threads with good server utilization. Apache JMeter allows you to focus on analyzing the situation, looking into measurements, response time, and client-server responses, which I find valuable."
"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 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."
"The performance and reporting of this solution have been its most valuable features."
"We find the product to be scalable."
"We can scale."
"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."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"he initial deployment process is easy."
 

Cons

"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."
"The reporting is not very good."
"Its reporting could be improved. There should be a better visual representation. That would be helpful for easy consumption of the reports."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"They should improve the solution on its UI front."
"In future releases, it would be helpful if there was an integration with ALM Octane."
"Improving JMeter's sync time would be beneficial."
"Automation is difficult in JMeter."
"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."
"I'd not sure if they have the same level of documentation for performance and security testing."
"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."
"The solution’s interface could be improved."
"It is very slow sometimes."
"I want the solution to be able to monitor Apache Kafka activity as well."
"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

"Since it's free, there's no need for extensive support or improvements in pricing."
"No licensing is required as it is a free, open-source tool."
"Apache JMeter is far less expensive than HP Performance Center."
"I was using the free version of the software."
"Free"
"It is free."
"JMeter is open source, so there are no licensing costs associated with it."
"Apache JMeter is a free open source solution and it is why we are using it."
"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."
