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."
"It is cost-effective and simple to use."
"Very user-friendly and easy to use."
"It's very easy to install, and it's very easy to code and develop the script."
"It gives accurate results and recommendations that we can implement to enhance the performance of websites."
"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."
"JMeter lets us generate virtual users and T-load, per our requirements. It's easy to configure and adjusting the virtual users according to the DPS we want to achieve."
"It's a powerful tool that is open source."
"It allowed us to understand the working and performance of the APIs."
"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."
"The initial setup is simple."
"The most valuable feature is the user interface because it provides a clear space for the URL, headers, body, prerequisites, and tests."
"This solution offers a free version."
"The API testing features are valuable."
"It is nice to have different workspaces. You have your personal workspace, and then you have a team workspace. In general, I like its UI. It is quite cool."
"With Postman you can do automation. Automation has increased efficiency by more than 30% or 40%. Because the speed has increased, it's also possible for us to do in-sprint automation testing."
"Given that Apache JMeter is a free and open-source tool, documentation improvement may not be a major concern, as it is mostly contributed on a voluntary basis. The essential information is already available. However, in terms of the interface, there are occasional bugs, and the tool may not address them as quickly as some users would like. Fixing defects and bugs might take a considerable amount of time, with users sometimes having to wait for several months or even a year for the next release to address specific issues."
"The memory utilization in JMeter is very poor."
"One of the drawbacks of JMeter is that it can't handle a large amount of load, which forces us to switch to other tools when we need to load more than a 5,000 or 10,000 user load."
"There are certain things like we can't merge custom metrics into the JMeter reports. We're limited to JMeter metrics, and other server metrics can't be integrated with JMeter dashboard. This forces us to rely on another tool."
"There could be improvements in terms of memory utilization. We are going to migrate away from JMeter in the near future."
"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."
"In Micro Focus LoadRunner we can go from the UI and we can configure it. There is no such feature in Apache JMeter. There should be UI-based recording history or logs."
"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."
"Postman does not have a check-in balance. Essentially what I mean by that is if there is something that is already configured on a particular device, it just overrides it without checking whether you really want to override it or not."
"We have previously used Tosca which allowed us to verify information using authentications. It would be useful if this was also possible using Postman. In a future release, Postman should connect to DB."
"There needs to be more flexibility surrounding the testing of SOAP APIs."
"I would like to have a code snippet where I can write a code and for the responses of the endpoints to be validated using my custom business conditions."
"Postman is a bit more of a complex tool, making it an area where improvements can be made."
"I live in Turkey, so for me, the value of dollar currency is high...Postman can change its pricing policy and decrease the prices for Turkey."
"The solution has some user interface difficulties when conducting environment collections."
"It would be better if we could integrate programming languages like .NET, Java, and JavaScript. It could also be more user-friendly."
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.

We monitor all API Testing Tools reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
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.
