Featured Reviews

NalinGoonawardana - PeerSpot reviewer
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.
