Leveraging cost-effective customization with powerful plugins but complexity reduction needed
Apache JMeter offers plugins for reporting and preparing test scenarios. It allows recording to customization, letting you download plugins to connect with databases or external systems. Despite being open source, it offers features comparable to paid tools, and its ability to customize and expand is particularly useful. Additionally, its open-source nature makes it cost-effective.
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 scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."
"We use Apache JMeter for load testing, where we provide the throughput time."
"JMeter's most valuable feature is the RegEx Extractor."
"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."
"It's a powerful tool that is open source."
"The solution offers a lot of plug-ins and a huge continuously developing community that is regularly offering new features and plug-ins."
"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."
"It's a free tool."
"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'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 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."
"We find the product to be scalable."
"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."
 

Cons

"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."
"Its reporting could be improved. There should be a better visual representation. That would be helpful for easy consumption of the reports."
"There could be improvements in terms of memory utilization. We are going to migrate away from JMeter in the near future."
"Apache should have a graphic interface."
"The installation needs some work. It could be simplified."
"The stability could be a bit better."
"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."
"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."
"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."
"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."
"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."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"I want the solution to be able to monitor Apache Kafka activity as well."
"It is very slow sometimes."
 

Pricing and Cost Advice

"There are operational costs related to using Amazon Cloud, but the tool itself."
"We use the open source version."
"Free"
"Apache JMeter is a free open source solution and it is why we are using it."
"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"This is an open-source solution, so there are no licensing costs associated with it."
"Apache JMeter is an open-source solution, so it's free to use."
"This is an open-source product."
"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."
"ReadyAPI Performance’s pricing is reasonable."
