We performed a comparison between Apache JMeter and k6 Open Source based on real PeerSpot user reviews.
Find out what your peers are saying about Apache, OpenText, Tricentis and others in Load Testing Tools."To me, what's most valuable in Apache JMeter is that it's a lightweight tool for application testing. It's the best load-testing tool for my company because Apache JMeter simulates your application during testing. Apache JMeter also creates threads with good server utilization. Apache JMeter allows you to focus on analyzing the situation, looking into measurements, response time, and client-server responses, which I find valuable."
"It is scalable. You can scale up to 1,000 users in JMeter. If you can put up four slave servers, you can easily ramp up to 1,000 users."
"It's a powerful tool that is open source."
"When someone in our organization wants to test web applications, they use Apache JMeter since they face no hurdles while using the solution."
"The most valuable features are the ability to capture the entire traffic of particular pages and the proper readability of entire pages and entire APIs."
"It's stable and reliable."
"It's very easy to install, and it's very easy to code and develop the script."
"Scripting with the solution is good."
"The standout feature of k6 is its strong focus on API performance testing."
"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."
"The reporting section of the solution can be better."
"In terms of setup, it could be nicer, to be honest. Sometimes, I get a little bit lost."
"The UI has room for improvement."
"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."
"The solution is not user-friendly, there is no framework for autocorrelation or parameterization."
"It should be easier to combine multiple scripts. If you have multiple scripts, you need to write a new script to combine those scripts. The virtual user generator is slow."
"The solution needs to improve reporting. Currently, there is not enough automation involved with the feature. For example, there should be an automatic way of saving reports."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
