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

"JMeter is easy to use for a user who doesn't have too much knowledge of programming or certain languages."
"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 most valuable features are the ability to capture the entire traffic of particular pages and the proper readability of entire pages and entire APIs."
"The reports and analysis tools are very good. They are the solution's most valuable features."
"It's a free tool."
"We really appreciate that the solution comes with a live community, which continuously provided plugins and support protocols."
"JMeter's most valuable feature is the RegEx Extractor."
"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."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"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."
"he initial deployment process is easy."
"The performance and reporting of this solution have been its most valuable features."
"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."
"We can scale."
"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."
 

Cons

"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"If JMeter could provide a web version of editing, that would be good."
"At times when we overload the application, it gets stuck...After the solution gets stuck due to overloading, we have to restart our computers. In short, the solution keeps crashing."
"From an improvement perspective, consider a scenario where your application needs to retrieve data from PayPal and store it in an Excel file in an external network."
"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."
"We would like some reporting and analysis tools to be added to this solution."
"Given that Apache JMeter is a free and open-source tool, documentation improvement may not be a major concern, as it is mostly contributed on a voluntary basis. The essential information is already available. However, in terms of the interface, there are occasional bugs, and the tool may not address them as quickly as some users would like. Fixing defects and bugs might take a considerable amount of time, with users sometimes having to wait for several months or even a year for the next release to address specific issues."
"You really need a technical team in order to really utilize the product."
"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."
"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."
"I want the solution to be able to monitor Apache Kafka activity as well."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"It is very slow sometimes."
"The solution’s interface could be improved."
"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

"No licensing is required as it is a free, open-source tool."
"Since it is an open-source product, buying or paying for any license is unnecessary. One just needs to download it to be able to use it."
"In terms of open-source adoption, it is completely free."
"This is an open-source solution, and there are no fees."
"This is an open-source product."
"The solution is free of cost as it is open source."
"Apache JMeter is a free tool."
"We are using the free version."
"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."
