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."
"The most valuable features are the integration with Jenkins and the reporting."
"One valuable feature of Apache JMeter is the ability to replicate scenarios where bulk files have to be uploaded via API."
"User-friendly and open source."
"It's stable and reliable."
"We use Apache JMeter for load testing, where we provide the throughput time."
"The solution has good transition controllers and distributed testing."
"Monetary benefits with Apache JMeter are notable since it doesn’t require a licensed version."
"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 find the product to be scalable."
"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 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."
"he initial deployment process is easy."
 

Cons

"There is room for improvement in the scripting concepts. The scripting and even the results and reports were very elaborative and informative in LoadRunner, but not in JMeter because everything has to be done manually."
"They should improve the solution on its UI front."
"The memory utilization in JMeter is very poor."
"In this tool, automation in general is almost non-existent. Everything is done manually."
"If the solution was GUI based, I believe that it would be more versatile."
"The UI has room for improvement."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"We would like some reporting and analysis tools to be added to this solution."
"We need some time to understand and configure the solution."
"I'd not sure if they have the same level of documentation for performance and security testing."
"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."
"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."
"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."
"It is very slow sometimes."
 

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."
"I was using the free version of the software."
"No licensing is required as it is a free, open-source tool."
"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."
"We didn't pay licensing fees for Apache JMeter because it's an open-source tool. We only paid for the machines where we installed Apache JMeter modules."
"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."
"We are using the free version, and if required, we can easily switch to the other version."
"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."
"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."
