Offers good scalability and has the ability to integrate with various systems and services
One area where k6 could improve is by introducing a GUI similar to JMeter. While k6 is a powerful tool for performance testing, it leans heavily towards coding. Having a GUI, even if it is a low-code approach, could make it more accessible to a broader audience. It would be beneficial to strike a balance where basic tasks can be performed graphically through a user-friendly interface, while still allowing the flexibility for more complex operations through code, similar to how JMeter operates. This could enhance the user experience and make k6 more approachable for those who may not be as comfortable with scripting.

IDE is simple and it's quick to complete the process but the reporting is complicated
You pay for the number of users that you're going to be utilizing. In order to scale up, you would have to pay for additional users, but for our use case, we're able to scale fairly easily. We have a license for 500, but we're using half of that for our initial workflow. For maintenance, as far as I'm aware, there's only one person really working on the maintenance of it and we only really have one user consistently using the software. He's a QA person. We don't have any plans to increase our usage. Even though we've had it for a while, we have a major push to start utilizing it more. I imagine we'll probably be using it and utilizing it across our QA team in the next year. We're in the process of determining whether we're going to keep it or not due to the fact that it is so expensive. That's why I've been researching alternatives for the RadView.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"The standout feature of k6 is its strong focus on API performance testing."
"The tool itself is very viable for us."
"Customer service is excellent; they're very responsive and willing to work extra hours, and in the first couple of hours that we were up and running, they taught us how to implement it and to figure out and negotiate AWS."
"They are the best of all of the vendors I deal with, hands down."
"The solution is simple and useful."
"The most valuable feature of this solution is reporting; it is interesting, intuitive, and we can do some parameterization."
"Technical support has been excellent, responsive, and helpful in trying to work through issues and questions."
"The analytics pack is probably one of the most powerful tools that I've seen."
"The ability to conceptualize the experience for users is great, the price as the bang for your buck is good, the user interface is quite user friendly, and the graphics make it easy to follow and are easy to identify."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"I would like to be able to edit a scenario instead of re-recording a scenario."
"It would be great, in addition to the load tool, it would be nice, if Radview offered a JavaScript based functional test tool as well."
"They can improve in the reporting - the ability to generate custom reports."
"We did have an issue with some of the script working incorrectly in our higher environments."
"Technical support is slow and wastes a lot of time, so it needs to be improved."
"Well there’s one issue when I have five or six scripts-- you have to set up different percentages and the number of connections and users, no matter how I tweak it seems that when I have one of the load scripts in the mix set, a percentage of less than 8-10%, there’s a probability that it won’t run at all."
"We have had a lot of trouble with this solution, and it is actually adapted to our application."
"The reporting side of things is really complicated. It's difficult to get out exactly what you're looking for, there are almost too many options."
