We performed a comparison between Apache JMeter and Postman based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: When comparing Apache JMeter and Postman, it is evident that Postman is the more popular choice. While both have great features and both share good flexibility and stability ratings, users of Postman seem to find fewer things lacking with it and are generally more satisfied. A noticeable difference between the two
"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 appreciate JMeter's simplicity and power for performance testing."
"The ease of use is the solution's most valuable feature. Also, the ability to easily create test cases is also very good. It's easy to just ramp up on the solution."
"The scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."
"The reporting features are really good. There's a lot less latency than other solutions."
"Apache JMeter is stable."
"The most valuable feature of Apache JMeter is its popularity. It is the best open-source tool with all the features needed."
"The solution is scalable."
"The variables part is good. We can easily define the variables and we don't have to manually do a change every time, it gets automatically updated."
"We are using the automation and performance testing tools."
"The most valuable feature of this solution is Collections."
"It's easy to see different versions of responses."
"It allowed us to understand the working and performance of the APIs."
"The most valuable features of the solution are that it is easy to use and user-friendly."
"In Postman, we have an option to directly import a call, make it a Postman collection, and execute it in a batch. This feature is very useful. It saves a lot of time. The manual effort is also reduced when we can just pick it in a Postman collection and then run and execute it to get the results."
"We can also submit requests multiple times and it allows us to capture the response each time by using utility scripts."
"The memory utilization in JMeter is very poor."
"The initial setup is complex and needs to be upgraded."
"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 stability could be a bit better."
"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."
"The user interface is a little bit tricky."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"Apache JMeter could use improvement in reporting. Currently, it isn't easy to generate reports in PDF format. While receiving reports in PDF format is possible, it requires a lot of customization. Additionally, when comparing the load test to others solutions it could improve."
"To get this email reporting function, we have to integrate Postman with Newman. If the two are not integrated, we won't be getting all these things in one group."
"I would like to see advanced automation in reference to Postman."
"We'd like to see some better UI in newer versions."
"The solution has some user interface difficulties when conducting environment collections."
"If they could implement auto-validations and assertions from SoapUI, that would be a very good feature."
"Version management could be simplified."
"There needs to be more flexibility surrounding the testing of SOAP APIs."
"Postman is a bit more of a complex tool, making it an area where improvements can be made."
Apache JMeter is ranked 3rd in API Testing Tools with 82 reviews while Postman is ranked 1st in API Testing Tools with 52 reviews. Apache JMeter is rated 7.8, while Postman is rated 8.2. The top reviewer of Apache JMeter writes "It's a free tool with a vast knowledge base, but the reporting is lackluster, and it has a steep learning curve". On the other hand, the top reviewer of Postman writes "Reliable and easy to expand with a helpful API network". Apache JMeter is most compared with BlazeMeter, Tricentis NeoLoad, OpenText LoadRunner Professional, Katalon Studio and ReadyAPI, whereas Postman is most compared with ReadyAPI Test, Tricentis Tosca, Katalon Studio, Apigee and Parasoft SOAtest.

Postman lets you easily define variables, which then get updated automatically. This is a huge time-saver and makes processes very efficient. We can also export the test cases we create and share them with our teams. Offering great collaboration code testing options and project storage, Postman is also possibly the best solution for testing REST APIs.
Developing environment compatibility could be better, though. When testing web services, there are some shortcomings; a visual component would be a great addition. There also should be better flexibility testing SOAP APIs.
Apache JMeter, which is open-source and has a free option, offers great performance. We like the scripting ability the most: once you have a good set of tests, you have a scripted document you can execute in a pipeline. Apache JMeter integrates well with other solutions.
The reporting could be better, though. Many of the reports are not concise enough and can be difficult to understand. There should also be a better way of saving reports. We also felt the installation could be simplified. Overall, the interface could be made more user-friendly.
Conclusion:
These solutions both perform many of the same functions and do them very well.
We ultimately chose Postman because we felt they offer better collaborative options and that the solution is more user-friendly over all. (You don’t have to be a tech genius to use it.) The UX is very fresh and easy to understand. Postman’s reporting process is simple to manage and easily shared. The solution scales easily and is very reliable and stable.
Postman is for API verification. It can be used for inspections of API as well.
JMeter is mainly used for performance tests - such as a load or stress test. Both tools have different perspectives, however API calls can be intersected between them.
