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 new version of the solution is stable."
"One valuable feature of Apache JMeter is the ability to replicate scenarios where bulk files have to be uploaded via API."
"The product helps me get the expected performance from applications or servers and reduces costs. It also enhances the performance of the services and helped them reach their ultimate capacity."
"The solution offers a lot of plug-ins and a huge continuously developing community that is regularly offering new features and plug-ins."
"This solution is very user-friendly, and allows for a lot of data capture when testing."
"JMeter's open-source nature allows us to create scripts easily, add any number of users during load tests, and handle large volumes of data without additional cost."
"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."
"The most valuable features are the integration with Jenkins and the reporting."
"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 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."
"We find the product to be scalable."
"he initial deployment process is easy."
"We can scale."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"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 UI could be better."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"Until now, JMeter is not supporting most of the protocols."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"Both scalability and stability could be improved in Apache JMeter."
"The solution is not user-friendly, there is no framework for autocorrelation or parameterization."
"To improve Apache JMeter, reducing the complexity of load generators and distribution testing would be beneficial."
"In this tool, automation in general is almost non-existent. Everything is done manually."
"I'd not sure if they have the same level of documentation for performance and security testing."
"We need some time to understand and configure the solution."
"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."
"The solution’s interface could be improved."
"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."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
 

Pricing and Cost Advice

"The main reason we chose Apache JMeter is that it is cost-effective and easy to use. There is no need to pay for additional services. Additionally, it does not require additional payment to vendors. The solution is open-source and free."
"This is an open-source product."
"Apache JMeter is far less expensive than HP Performance Center."
"It is open source. There are no licensing costs associated. If you need enterprise support, you'll probably end up paying for a license. You would also factor in the infrastructure cost, but that's not significant."
"Apache JMeter is a free open source solution and it is why we are using it."
"JMeter is open source, so there are no licensing costs associated with it."
"Free"
"In terms of open-source adoption, it is completely free."
"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."
