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

"The solution is free. You don't need to worry about licensing costs."
"The reporting features are really good. There's a lot less latency than other solutions."
"Scripting with the solution is good."
"Monetary benefits with Apache JMeter are notable since it doesn’t require a licensed version."
"The most valuable features are the integration with Jenkins and the reporting."
"We are using it just for load testing. We are using its free version, and it is scalable."
"The most valuable features of Apache JMeter are user-friendliness, large resource, and the quality of assistance they provide. Additionally, it is easy to integrate with cloud platforms, such as AWS."
"To me, what's most valuable in Apache JMeter is that it's a lightweight tool for application testing. It's the best load-testing tool for my company because Apache JMeter simulates your application during testing. Apache JMeter also creates threads with good server utilization. Apache JMeter allows you to focus on analyzing the situation, looking into measurements, response time, and client-server responses, which I find valuable."
"The performance and reporting of this solution have been its most valuable features."
"he initial deployment process is easy."
"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."
"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's like a centralized interface that allows us to increase the quality of our APIs."
"We can scale."
"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."
 

Cons

"Apache JMeter could use improvement in reporting. Currently, it isn't easy to generate reports in PDF format. While receiving reports in PDF format is possible, it requires a lot of customization. Additionally, when comparing the load test to others solutions it could improve."
"The solution needs to improve reporting. Currently, there is not enough automation involved with the feature. For example, there should be an automatic way of saving reports."
"You really need a technical team in order to really utilize the product."
"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."
"Some features still require a certain knowledge level to use effectively, and making these features more user-friendly would be beneficial."
"JMeter is lagging when it comes to GUI performance testing because we need to install some third-party plugins for recording the GUI script, and the performance isn't very reliable."
"The UI needs some work. The first time I used JMeter, I couldn't record the full scenario to mimic the user experience. Since then, they have introduced some plugins and a third-party tool called BlazeMeter."
"It should be easier to combine multiple scripts. If you have multiple scripts, you need to write a new script to combine those scripts. The virtual user generator is slow."
"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."
"I'd not sure if they have the same level of documentation for performance and security testing."
"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."
"The solution’s interface could be improved."
"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."
"It is very slow sometimes."
 

Pricing and Cost Advice

"There are operational costs related to using Amazon Cloud, but the tool itself."
"This is an open-source solution, so there are no licensing costs involved."
"The solution is free of cost as it is open source."
"I was using the free version of the software."
"It is free."
"This is an open-source product."
"Apache JMeter is a free, open-source solution."
"The solution is open source."
"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."
