k6 is written in Go, but scripts are written in Javascript. LoadImpact had previously consisted of the SaaS platform (now k6 Cloud) and professional services. K6 is an open source load testing tool released by LoadImpact in 2017. At the time of this writing, the latest version of JMeter is 5.4. Although scripts can also be extended using code, majority of the scripting in JMeter is done using the UI. JMeter took what other companies were charging a lot of money for and published it online for everyone to use- for free. It was first released in 1998, and it made waves because of its audacity in taking on more popular but proprietary load testing tools. JMeter is an open source load testing tool built entirely in Java by the Apache Foundation. Secondly, I want to share my reasons for wanting to explore k6 as a load testing tool- the same reasons that ultimately convinced me to join the team that builds it. So what am I doing on the k6 site, talking about how much I love JMeter? Well, firstly, it turns out that the k6 team is pretty open and transparent, especially about potential improvements in k6. When I joined the k6 team in late November, the foremost question on my mind was 'How does this compare to JMeter?' You see, I come from a performance testing consulting background, and in the last few years, JMeter has been far and away my tool of choice.
