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

"It is scalable. You can scale up to 1,000 users in JMeter. If you can put up four slave servers, you can easily ramp up to 1,000 users."
"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."
"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 is cost-effective and simple to use."
"It is open source as well as relatively extendable. It allows us to extend and add additional functionality and features. Its deployment is also very easy."
"The solution's initial setup is easy."
"The performance of the solution is excellent."
"We find the ease of use and the reports and graphs available valuable."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"he initial deployment process is easy."
"We find the product to be scalable."
"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 can scale."
"The performance and reporting of this solution have been its most valuable features."
"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."
 

Cons

"They should improve the solution on its UI front."
"To the best of my knowledge, the documentation could be improved. It should be enhanced to better support newcomers. Currently, only people with some experience can easily understand the content. Including more sample programs, applications, and use cases would help many more people adapt to using the solution."
"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."
"JMeter output reports can be difficult to understand without training."
"The memory utilization in JMeter is very poor."
"It requires integration with other tools for live metrics, which is time-consuming."
"In this tool, automation in general is almost non-existent. Everything is done manually."
"There could be improvements in terms of memory utilization. We are going to migrate away from JMeter in the near future."
"The solution’s interface could be improved."
"I'd not sure if they have the same level of documentation for performance and security testing."
"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."
"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."
"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 we are using an outsourced solution, it is not paid for by our company."
"I switched to Apache because it is free. Other tools are much too expensive and can cost up to $50,000 a year if you are looking at commercial options."
"Apache JMeter is far less expensive than HP Performance Center."
"The solution is open-source."
"We didn't pay licensing fees for Apache JMeter because it's an open-source tool. We only paid for the machines where we installed Apache JMeter modules."
"Apache JMeter is a free open source solution and it is why we are using it."
"I haven't looked into it. Most of our projects are nonprofit or grant-based. Everything is public commons, so we don't really have to worry about that so much."
"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."
"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."
