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

"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."
"JMeter is a free tool with a large user population, which comes in handy because we have a vast knowledge base to tap into when needed. It's also easier to hire consultants who know JMeter."
"JMeter can be integrated with most open-source platforms like Grafana, Prometheus, or even with custom-made tools by extending it and integrating from GitHub."
"We are using it just for load testing. We are using its free version, and it is scalable."
"JMeter lets us generate virtual users and T-load, per our requirements. It's easy to configure and adjusting the virtual users according to the DPS we want to achieve."
"The solution has good transition controllers and distributed testing."
"This solution is easier to use than any other tool in the market; there is not even a requirement to learn a lot of scripting in order to use it."
"It is scalable. You can scale up to 1,000 users in JMeter. If you can put up four slave servers, you can easily ramp up to 1,000 users."
"We can scale."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"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."
"he initial deployment process is easy."
"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."
"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."
 

Cons

"The installation needs some work. It could be simplified."
"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."
"Currently, the integration pipeline is implemented by using Jenkins or a similar tool platform. These are continuous integration tools. As far as I know, integration is done by using custom scripts. It would be good if the integration with a continuous integration pipeline, like Jenkins or Hudson, can be done out of the box without using a script."
"The reporting section of the solution can be better."
"Improving JMeter's sync time would be beneficial."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."
"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'd not sure if they have the same level of documentation for performance and security testing."
"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."
"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."
"It is very slow sometimes."
"I want the solution to be able to monitor Apache Kafka activity as well."
 

Pricing and Cost Advice

"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"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."
"The product has reasonable pricing."
"Free"
"Apache JMeter is an open-source solution, so it's free to use."
"Apache JMeter is a free tool."
"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."
"Everything is included, and there are no additional costs."
"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."
