Executive SummaryUpdated on Jan 6, 2025

Apache JMeter and ReadyAPI Performance are tools competing in the performance testing category. JMeter seems to have the upper hand due to its open-source nature and community support, making it cost-effective compared to ReadyAPI's fee-based model.

Features: Apache JMeter is favored for its open-source nature, flexibility, and wide array of plugins, making it cost-effective for performance testing. It supports load testing across various protocols and integrates well with CI/CD pipelines. ReadyAPI Performance offers comprehensive API testing with robust reporting and automation capabilities, providing ease of use for complex testing scenarios but at a cost.

Room for Improvement: Apache JMeter lacks in GUI performance, often becoming unresponsive under large loads, and presents issues in reporting and configuration. Its reliance on community support instead of dedicated technical support is also a downside. ReadyAPI Performance is criticized for its cost and lack of a free tier suitable for students or small operations despite being robust.

Ease of Deployment and Customer Service: Apache JMeter offers diverse deployment options including on-premises and hybrid cloud environments, supported by strong community resources but lacking official support. ReadyAPI Performance targets on-premises and public cloud setups, providing established customer service, though it comes at a cost, contrasting JMeter’s free community-driven support model.

Pricing and ROI: Apache JMeter, as an open-source tool, incurs no licensing costs, making it attractive for budget-conscious organizations, with a competitive ROI especially for limited scaling. ReadyAPI Performance involves tiered pricing with licensing fees, which some users find justified by its advanced features, but it might not be economical for small operations or educational purposes.

Performance testing has become central and reporting has provided clear insights for our teams

We do have command prompt related or CLI functionality with Apache JMeter, so it is easier. However, since it is open source, much work has not been put into the GUI part. The GUI could definitely be enhanced. One drawback which I can see when I compare it with other tools is the amount of cache that it uses, the memory that it uses. It becomes very difficult to work with when we have a lot of requests that need to be processed. Anything more than 10,000 requests becomes a bit of an unfavorable task when using Apache JMeter altogether. Otherwise, it does help anyone who is starting off with performance testing.

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 features that I appreciate are quite basic. It is easy to ramp up the threads and start calling the application. A lot of connectors can already be found within Apache JMeter, but we are not using the entire set because the integration between the customers and platform is based on HTTP. We are just going to produce lots of HTTP sequences."

"Apache JMeter helps my testing analysis by providing precise reports; the HTML format report gives me the exact transactions, response times, and graphs that show average response times, as well as throughput per second."

"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."

"I like the ease of using JMeter, as it can be downloaded and used to record and run load tests, and it can record, run and create reports easily without the need to have licenses, complex installations and paid support."

"It's open source, so I like that about the product. And there's a lot of community support for it."

"It's stable and reliable."

"We appreciate that the solution is free to use, as an open-source tool."

"When there's a high number of TPS I can achieve more transactions per seconds given the hyper-limitations."

More Apache JMeter pros

"The performance and reporting of this solution have been its most valuable features."

"We can scale."

"It is a very good and handy product, there are so many features, and it is getting more popular day by day."

"It's like a centralized interface that allows us to increase the quality of our APIs."

"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."

"We find the product to be scalable."

"Eventually, we enhanced the whole automation, and how it should get integrated with the hardware, or another tool like Jenkins for CI/CD automation."

Cons

"The solution needs more metrics for reporting."

"Improving JMeter's sync time would be beneficial."

"The tool needs to have a better Graphical User Interface. Many of the solution's features are difficult to understand due to the complex user interface and user experience. The product needs to add plugins. It should also work on the integration with external partners like IDE and API gateways."

"I sometimes found the documentation to be not as explanatory as I would've liked it. In the cases that I can think of, I was looking for a rather hand-holding approach with Step A, B, and C, but then I realized that with a product that is open source like this, you can't do handholding. That is because there are so many different uses and different unique environments and setups for it, but I remember thinking a few times that if they only just said this."

"The UI could be better. It can have some Reach UI also, which would be helpful, and maybe a relatively simpler way of using it."

"At times when we overload the application, it gets stuck...After the solution gets stuck due to overloading, we have to restart our computers. In short, the solution keeps crashing."

"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."

"If you go above the 200 user mark, the application creates a bottleneck and that's one of its major drawbacks."

More Apache JMeter cons

"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."

"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."

"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."

"It is very slow sometimes. If they could improve its performance, it would be really great for the users."

"It is very slow sometimes."

"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."

Pricing and Cost Advice

"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."

"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."

"Everything is included, and there are no additional costs."

"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"

"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."

"We use the open source version."

"It is free."

"Apache JMeter is an open-source solution, so it's free to use."

More Apache JMeter pricing and cost advice

"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."

"ReadyAPI Performance’s pricing is reasonable."
