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

"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."
"Overall, I would rate Apache JMeter as eight to nine out of ten."
"The most valuable feature for us is the available information on the forums and to be able to discuss and get answers from the people that are involved in using this tool."
"The most valuable feature of this solution is that it is free."
"They can easily view the results and gain valuable insights."
"The solution has good transition controllers and distributed testing."
"The solution is free. You don't need to worry about licensing costs."
"It is an open-source tool that is easy to use. It can be easily integrated with multiple tools, including Selenium."
"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 should improve the solution on its UI front."
"There is some work to be done with the integration."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"At present, if the number of virtual users increases beyond 10,000 when testing, then it results in a Java heap which causes the solution to crash."
"Apache JMeter could be a more user-friendly product from the end user's perspective."
"It will be much easier, and beneficial for the individual to run it on their own machines rather than having a high-end infrastructure, more CPUs, or more memory that has been consumed by Apache JMeter."
"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."
"It requires integration with other tools for live metrics, which is time-consuming."
"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

"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."
"The product has reasonable pricing."
"The solution is open source."
"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"
"The solution is free of cost as it is open source."
"This is an open-source solution, so there are no licensing costs associated with it."
"I switched to Apache because it is free. Other tools are much too expensive and can cost up to $50,000 a year if you are looking at commercial options."
"Apache JMeter is a free tool."
