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 thread groups, samplers, and listeners, which are all determined by the script's requirements, are the most valuable features of this solution."
"Apache JMeter is stable."
"Apache JMeter is well-known and widely used among developers, particularly on popular developer forums. While it may not have the most user-friendly interface, it offers strong support through official manuals and various articles from companies providing load testing services. The tool is free, has a substantial community, and serves as a fundamental choice for testers, especially those new to performance testing. While other tools like K6 may be more developer-oriented, JMeter's affordability and accessibility make it suitable for those without extensive performance testing experience."
"What I like best about Apache JMeter is its user-friendly GUI because even if you don't have very good coding knowledge or understanding, or even if you don't come from a development background, you can still use the solution with just a few clicks. This is what's unique about Apache JMeter, in comparison with other tools in the market. As Apache JMeter is open source, when there's a missing feature, you can search in several community blogs for plugins that you can use to modify Apache JMeter to meet your requirements, and this is another advantage."
"They can easily view the results and gain valuable insights."
"I use all the tools, but one feature that stands out is JMeter's ability to test when services are sending a particular kind of request. We are using specific ports to send queries, and assess the performance based on the time it takes these queries to respond. You can use it with stuff other than the web performance."
"The most valuable features of Apache JMeter are user-friendliness, large resource, and the quality of assistance they provide. Additionally, it is easy to integrate with cloud platforms, such as AWS."
"It is easy to set up."
"he initial deployment process is easy."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"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."
"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 find the product to be scalable."
"The performance and reporting of this solution have been its most valuable features."
"We can scale."
"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."
 

Cons

"The reporting is not very good."
"It should start supporting the presentation layer. It currently provides performance testing specifically at the application and API level. It can be extended to the presentation layer, which includes mainly Angular and React frameworks. It should also be easy to use and easy to train people."
"The tool should be made a bit more robust, and better support should be made available."
"Report generation needs to be improved. It is quite difficult to get to."
"Improving JMeter's sync time would be beneficial."
"While using Apache JMeter, we are unable to view the graph while the test is running because it consumes resources, which is a drawback. With BlazeMeter, you can view the results in real-time."
"Apache JMeter could be a more user-friendly product from the end user's perspective."
"Currently, the integration pipeline is implemented by using Jenkins or a similar tool platform. These are continuous integration tools. As far as I know, integration is done by using custom scripts. It would be good if the integration with a continuous integration pipeline, like Jenkins or Hudson, can be done out of the box without using a script."
"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."
"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."
"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."
"The solution’s interface could be improved."
 

Pricing and Cost Advice

"Since it's free, there's no need for extensive support or improvements in pricing."
"Apache JMeter is a free tool."
"Free"
"In terms of open-source adoption, it is completely free."
"JMeter is open source, so there are no licensing costs associated with it."
"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"
"Apache JMeter is a free tool."
"This is an open-source solution, so there are no licensing costs associated with it."
"ReadyAPI Performance’s pricing is reasonable."
"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."
"We find the cost to be affordable."
