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 recording and playback functionality is helpful."
"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."
"The most valuable features are the ability to capture the entire traffic of particular pages and the proper readability of entire pages and entire APIs."
"JMeter's most valuable feature is the RegEx Extractor."
"It's a free tool."
"The solution is free. You don't need to worry about licensing costs."
"It is an open-source tool that is easy to use. It can be easily integrated with multiple tools, including Selenium."
"It is very quick and user-friendly."
"he initial deployment process is easy."
"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."
"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."
"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."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"We can scale."
 

Cons

"One of the drawbacks of JMeter is that it can't handle a large amount of load, which forces us to switch to other tools when we need to load more than a 5,000 or 10,000 user load."
"There is some work to be done with the integration."
"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."
"Report generation needs to be improved. It is quite difficult to get to."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"The solution could use some sort of educational features to offer tips and hints to help users navigate it better. They should improve the manuals and help files."
"In this tool, automation in general is almost non-existent. Everything is done manually."
"Both scalability and stability could be improved in Apache JMeter."
"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."
"We need some time to understand and configure the solution."
"The solution’s interface could be improved."
"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 client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"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."
 

Pricing and Cost Advice

"Apache JMeter is a free open source solution and it is why we are using it."
"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."
"Everything is included, and there are no additional costs."
"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"The solution is open source with no user fees or licenses."
"In terms of open-source adoption, it is completely free."
"There are operational costs related to using Amazon Cloud, but the tool itself."
"This is an open-source product."
"We find the cost to be affordable."
"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."
