Lighter on the RAM and has native Grafana support
The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process. Recently, I had a case where I was using another tool, and there wasn't enough memory for it because it required more RAM. k6 Open Source, on the other hand, is lighter and doesn't have a UI, which is beneficial. An engineer I was training could use k6 Open Source scripts even without my help. The tool is more efficient and has native support with Grafana, as both are developed by the same company. This integration enhances monitoring and loss ratio tracking. Thanks to its intelligent GUI, k6 Open Source's design is simpler, particularly for complex scenarios. When we need to manage hundreds of thousands or millions of transactions per minute, the solution becomes a game-changer compared to JMeter.

Need improvements ,but has cloud and on-premises options
The solution is not in an optimal state. During POC, we analyzed tool is kept on upgrading. The patch deployment is happening in parallel, things that are working today are not working tomorrow. We eventually sorted it out with help of CSM. We integrated this tool with other software such as Azure client, but many times without a valid or visible reason, the connectivity was breaking. Improvement suggestions- The dashboard creation for the reporting needs to be easier. Currently, the solution does not support multiple script executions and we would like to see support for this.
