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

"JMeter lets us generate virtual users and T-load, per our requirements. It's easy to configure and adjusting the virtual users according to the DPS we want to achieve."
"It is scalable. It is cloud-based."
"The ease of use is the solution's most valuable feature. Also, the ability to easily create test cases is also very good. It's easy to just ramp up on the solution."
"JMeter is user-friendly, and that's a notable advantage of JVTech. It's straightforward and easy to use, unlike some other load testing tools, making it very easy to understand."
"It's open source, so I like that about the product. And there's a lot of community support for it."
"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."
"Overall, I would rate Apache JMeter as eight to nine out of ten."
"It is very quick and user-friendly."
"We can scale."
"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 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."
"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."
"The performance and reporting of this solution have been its most valuable features."
"he initial deployment process is easy."
 

Cons

"The user interface is a little bit tricky."
"Because so much is being done these days with authentication processes, a better system for either getting bearer tokens or some kind of token-based authentication prior to executing APIs would benefit the product. It is there, and you can do things. It is just not real clean at this point. There should be a better authentication process for JMeter or some automation or better guidelines for gaining and utilizing tokens on the fly."
"They can improve it a little bit in terms of distribution load testing. We struggled with it during the distribution. In terms of reporting, runtime monitoring is not currently included, and it should be included. They can also improve it on the reporting side in terms of the comparison of the reports. They can also focus more on integration with CI/CD. Currently, people are using their own customized tools. It would be nice if Apache can provide some standard tools and procedures for integration with CI/CD tools like DPR. There are some tools, but it would be nice if official standard tools and procedures are available."
"The reporting section of the solution can be better."
"There is room for improvement in the scripting concepts. The scripting and even the results and reports were very elaborative and informative in LoadRunner, but not in JMeter because everything has to be done manually."
"The memory utilization in JMeter is very poor."
"It will be much easier, and beneficial for the individual to run it on their own machines rather than having a high-end infrastructure, more CPUs, or more memory that has been consumed by Apache JMeter."
"Considering the kinds of tests we are performing here, where we launch several tests at the same time as a batch request, JMeter is not the best tool for the job. Those kinds of things could be done easily with other tools, like T6."
"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."
"It is very slow sometimes."
"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."
"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."
"We need some time to understand and configure the solution."
"The solution’s interface could be improved."
 

Pricing and Cost Advice

"Everything is included, and there are no additional costs."
"The solution is open-source."
"Apache JMeter is far less expensive than HP Performance Center."
"Apache JMeter is a free tool."
"Apache JMeter is an open-source solution, so it's free to use."
"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."
"We are using the free version, and if required, we can easily switch to the other version."
"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"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."
