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

"I appreciate JMeter's simplicity and power for performance testing."
"Any front-end technologies like Angular, React, or others might access the services. Therefore, you must ensure that using SAP with JMeter works fine. Unless you ensure this, the front-end team may not access the services properly."
"One valuable feature of Apache JMeter is the ability to replicate scenarios where bulk files have to be uploaded via API."
"The scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."
"A lot of things are valuable. It is free. It has a lot of features, such as report generation and integration with CI/CD, which makes it very competitive with the other paid solutions available in the market. It is a good solution."
"What I like best about Apache JMeter is its user-friendly GUI because even if you don't have very good coding knowledge or understanding, or even if you don't come from a development background, you can still use the solution with just a few clicks. This is what's unique about Apache JMeter, in comparison with other tools in the market. As Apache JMeter is open source, when there's a missing feature, you can search in several community blogs for plugins that you can use to modify Apache JMeter to meet your requirements, and this is another advantage."
"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 solution's initial setup is easy."
"We find the product to be scalable."
"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."
"The performance and reporting of this solution have been its most valuable features."
"he initial deployment process is easy."
"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'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

"It should start supporting the presentation layer. It currently provides performance testing specifically at the application and API level. It can be extended to the presentation layer, which includes mainly Angular and React frameworks. It should also be easy to use and easy to train people."
"Self-healing and page rendering for the end-users are not available in Apache JMeter."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"Apache JMeter may have difficulty recognizing dynamic objects in some critical cases, which can lead to challenges in terms of object identification."
"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."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"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."
"In Micro Focus LoadRunner we can go from the UI and we can configure it. There is no such feature in Apache JMeter. There should be UI-based recording history or logs."
"I'd not sure if they have the same level of documentation for performance and security testing."
"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."
"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 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."
 

Pricing and Cost Advice

"Apache JMeter is a free open source solution and it is why we are using it."
"I haven't looked into it. Most of our projects are nonprofit or grant-based. Everything is public commons, so we don't really have to worry about that so much."
"No licensing is required as it is a free, open-source tool."
"Everything is included, and there are no additional costs."
"We use the open source version."
"It is free."
"It is open source. There are no licensing costs associated. If you need enterprise support, you'll probably end up paying for a license. You would also factor in the infrastructure cost, but that's not significant."
"This is an open-source solution, so there are no licensing costs involved."
"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."
