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.
KashifJamil - PeerSpot reviewer
Supports web and mobile applications, very scalable, very stable, and wonderful support
There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies.

Quotes from Members

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

Pros

"The reporting features are really good. There's a lot less latency than other solutions."
"I appreciate JMeter's simplicity and power for performance testing."
"The thread groups, samplers, and listeners, which are all determined by the script's requirements, are the most valuable features of this solution."
"The recording and playback functionality is helpful."
"Apache JMeter is well-known and widely used among developers, particularly on popular developer forums. While it may not have the most user-friendly interface, it offers strong support through official manuals and various articles from companies providing load testing services. The tool is free, has a substantial community, and serves as a fundamental choice for testers, especially those new to performance testing. While other tools like K6 may be more developer-oriented, JMeter's affordability and accessibility make it suitable for those without extensive performance testing experience."
"It is open source as well as relatively extendable. It allows us to extend and add additional functionality and features. Its deployment is also very easy."
"I like the fact that JMeter integrates well with other tools."
"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 can support both web applications and mobile applications, and in certain cases, it can also support testing of desktop applications or software-based applications. You can write web applications, mobile applications, and software-based applications."
"Technical support is very good. I'm very satisfied with the assistance we've received so far."
 

Cons

"Apache JMeter's UI can be made more colorful."
"The reporting is not very good."
"In terms of setup, it could be nicer, to be honest. Sometimes, I get a little bit lost."
"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."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"The UI needs some work. The first time I used JMeter, I couldn't record the full scenario to mimic the user experience. Since then, they have introduced some plugins and a third-party tool called BlazeMeter."
"The interface could be made more user-friendly."
"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."
"There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies."
"The solution is not easily scalable. If you want to extend the solution, you need to purchase a different kind of license. You also have to work with the IBM team to assist in scaling."
 

Pricing and Cost Advice

"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."
"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."
"It is free."
"In terms of open-source adoption, it is completely free."
"Apache JMeter is a free tool."
"Free"
"The solution is open source with no user fees or licenses."
"It is much cheaper than Micro Focus LoadRunner. We need perpetual licenses. Support is included in the first sale. After that, you need to renew support every year."
