Featured Reviews

Shashidhara Allalappa - PeerSpot reviewer
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.
Shiju Chandran - PeerSpot reviewer
Good performance testing, simple UI, and the ability to run the same script across different domains
StresStimulus simulates browser HTTP calls. I would love to see where it can also simulate a real browser to measure visually complete time. For example, to be something similar to TruClient. We run tests on SQL statements and stored procedures directly, even before integrating with UI. I wish there were a way to connect to my application DB and run SQL queries using a JDBC connection. In a world where the applications are changing every day, I hope StresStimulus comes up with an option to compare HTTP requests before and after deployment and tell me what requests have changed. This would help avoid rescripting every time, and this would be a huge deal.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We like that Apache JMeter has different features and different plugins and that they are free of charge."
"JMeter is basically the art of the entire performance testing process."
"It's easy to set up."
"We had some challenges testing HTTP/2 APIs, which are becoming more prevalent with advancements like 5G. So, we added another plugin to help with HTTP/2 API load testing. Apache JMeter, with additional plugins, now supports HTTP/2, which is critical as everyone moves from HTTP/1 to HTTP/2."
"The solution is scalable."
"It's a free tool."
"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."
"The performance of the solution is excellent."
"Compared to other tools, there is not a whole lot to Stress Stimulus UI. This makes it easy to use, be it while scripting, executing, or having to train someone new to the team."
"Designed to be a modern testing tool, StresStimulus made it easy for us to upgrade from an older deprecated testing tool and adapt to Agile DevOps testing principles by shifting left with performance testing."
"Technical support is great."
 

Cons

"They can improve it a little bit in terms of distribution load testing. We struggled with it during the distribution. In terms of reporting, runtime monitoring is not currently included, and it should be included. They can also improve it on the reporting side in terms of the comparison of the reports. They can also focus more on integration with CI/CD. Currently, people are using their own customized tools. It would be nice if Apache can provide some standard tools and procedures for integration with CI/CD tools like DPR. There are some tools, but it would be nice if official standard tools and procedures are available."
"The solution could use some sort of educational features to offer tips and hints to help users navigate it better. They should improve the manuals and help files."
"There is some work to be done with the integration."
"The stability could be a bit better."
"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."
"The installation needs some work. It could be simplified."
"The reports in Apache JMeter could improve."
"Apache JMeter may have difficulty recognizing dynamic objects in some critical cases, which can lead to challenges in terms of object identification."
"We run tests on SQL statements and stored procedures directly, even before integrating with UI. I wish there were a way to connect to my application DB and run SQL queries using a JDBC connection."
"StresStimulus has a dedicated blog where users of the tool can log new feature requests or enhancements to existing features."
"Result analysis (snap-out tabs for side-by-side comparisons) need improvement."
 

Pricing and Cost Advice

"In terms of open-source adoption, it is completely free."
"Since it's free, there's no need for extensive support or improvements in pricing."
"No licensing is required as it is a free, open-source tool."
"JMeter is open source and available free of charge."
"The solution is open source."
"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"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 associated with it."
