Disagree. Old? I guess, but that doesn’t mean bad … it has recent feature development and is currently maintained. Crusty is not an adjective I would use, which seems like more ageism. It’s not an amazing GUI, but it’s very powerful. It will do whatever you want. It's quite flexible and easy to define what I need it to do, to store and load configuration, and it has very meaningful reports. All of these things are pretty easy. A one-size-fits all paid service could give you 3-click interactions and glossy charts, but at the cost of control and understanding what's really going on, and you're more likely to have wrong assumptions about what's happening. Summary: load testing is just complicated enough that it requires effort, thought, and a good toolset. Also K6 may be good or whatever, but it is a paid service. JMeter is free.
