"Load Testing Ease of Use"
Pros: It is one if Easy and user friendly tool. User can perform Load Testing by making multiple Virtual users, increasing Threads on any application. Best Part it is Open source tool and Java design , user can use the API for the project and find the Test Results. Saves user time and has great scalability for Load Test for functional behavior and measure performance.
Cons: Sometime very secure application can face issue during the setups , as proxy issues can hinder the setup and make setup complicated. As it is open source there is no much support help, user need to learn from online portals or youtube, which helps enough.
"Best tool for stress test and functional testing"
Overall: We use JMeter principally to stress tests our rest services. It's easy to check the response and to execute additional steps programatically. We also use JMeter sometimes to execute functional tests, also WEB UI tests checking html response body elements. Very useful is the possibility to turn on/off variables depending on your target testing environment.
Pros: JMeter is very intuitive and easy to use. UI is simple but full of features. With many plugins available for free and the possibility to write them by your own the features are infinity. Test cases can be built with various different steps, each one controlled programatically if you want.
Cons: When used to execute parallelized stress tests CPU and RAM become very stressed. Some UI improvement can be done to make more easy the daily work.
"Free and Open Source Performance Testing"
Overall: JMeter is fine if you have low or no budget, if you dont have advanced needs. If you need more, you can build your custom Java module and integrate it.
Pros: JMeter is very flexible and once you have recorded your test script you can set it up to run from multiple on-premises load generators. You can also re-use the script with some cloud performance testing tools like Blazemeter if you need to scale up.
Cons: Unfortunately its reporting features do not cover some important metrics like 97th 98th 99th percentiles without much hacking, or the possibility to view detailed metrics for each secondary page elements like images/css/js files out of the box.

Overall: A great performance testing tool for APIs.
Pros: Great tool for API functional/Performance testing
Cons: Its JAVA dependency, however it can be sorted by using other tools providing JDK
"Great free tool to run API Performance testing"
Overall: Amazing freeware to create and execute API performance testing
Pros: Its capability to perform high load and stress API performance testing.
Cons: Its dependency on JAVA generates some issues with my company policies
"A great experience for API Functional & Performance testing"
Overall: A great experience for API Functional & Performance testing
Pros: Best free tool to carry on API performance Testing
Cons: It is not easy to carry on UI performance testing.
"My favorite Great tool"
Overall: My favorite tool for load testing. Lots of options and visible results where you can view test results

"Analyzing load and stress tests with Apache JMeter"
Overall: Detailed stress test reports on web applications.
Pros: Its main advantage is that it is open source, which allows modifications to be made so that it adapts and at the same time does not generate costs. In addition, it generates detailed reports such as: response time, performance by protocol and others that allow to identify the limits in the performance of the web page.
Cons: For some types of web applications it gets more complicated, sometimes generating reports with higher than normal error rates, for example applications that use real-time communication.Although its use does not require a technical level, to evaluate the results it does, and this is good because the professionals themselves know what improvements to make to solve the problems encountered.
"JMeter - Recommended Tool for Performance and API Testing"
Overall: Using Apache JMeter, from setup and installation to actual usage, is very satisfying and worth it. You'll definitely learn a lot from this tool and the fact that there are several articles, forums, and tutorials about it, makes it really trustworthy. I suggest you JMeter if you will be doing performance and API testing in your projects.
Pros: I am a software tester and I can recommend JMeter as a tool for performance and API testing. It is open-source so you never have to spend money for this tool -- yet, the functionalities it holds are something you will need for your testing. With JMeter, you can do load testing, stress testing, endurance testing, API testing, and many more. The documentation and tutorials that you can find for JMeter are helpful so you won't be lost if you are a first time user.
Cons: Since it is an open-source tool, you cannot expect that the UI of the tool is very pretty. While it is easy to use, it can be a little bit intimidating at first since some parts are technical -- however, if you will be referring to the tutorials out there, you will definitely get use to it. So even if there are so many performance testing tools out there, I still recommend JMeter!
