Shashidhara Allalappa - PeerSpot reviewer
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

"When someone in our organization wants to test web applications, they use Apache JMeter since they face no hurdles while using the solution."
"It's a free tool."
"The reporting features are really good. There's a lot less latency than other solutions."
"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."
"Very user-friendly and easy to use."
"The biggest thing I liked about it is that there is a huge user base out there, and being shareware and being Apache, if I have any question on how to get something done, I get 18 different answers. Out of those, there would be at least a few good approaches for what I was trying to do. So, the support system out there is most valuable."
"It's very useful for performance and load testing."
"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."
"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."
"The performance and reporting of this solution have been its most valuable features."
"he initial deployment process is easy."
"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."
"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."
 

Cons

"The solution is not user-friendly, there is no framework for autocorrelation or parameterization."
"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."
"To improve Apache JMeter, reducing the complexity of load generators and distribution testing would be beneficial."
"The solution needs more metrics for reporting."
"Modeling a test is difficult. If you don't have much knowledge, you won't be able to do it easily. Testing APIs is also difficult."
"Both scalability and stability could be improved in Apache JMeter."
"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 tool needs improvements related to client-side metrics, integrating with tools like YSlow or HTTP Watch, and enhancing mobile testing capabilities."
"I want the solution to be able to monitor Apache Kafka activity as well."
"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."
"I'd not sure if they have the same level of documentation for performance and security testing."
"It is very slow sometimes."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"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."
"The solution’s interface could be improved."
 

Pricing and Cost Advice

"Everything is included, and there are no additional costs."
"The tool is open-source."
"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."
"It is free."
"Apache JMeter is far less expensive than HP Performance Center."
"We use the open source version."
"The solution is open source with no user fees or licenses."
"The product has reasonable pricing."
"ReadyAPI Performance’s pricing is reasonable."
"We find the cost to be affordable."
"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."
