Looks like a neat tool for learning k8s without paying for lots of nodes. I bought a used Dell R620 so was able to create a dozen VMs to test with, but something like this could be a way to do something similar without requiring the big hardware.

Also a clever name for the project.

May also have a place in a CI stack

minikube is a VM basically. This emulates thousands of nodes on your laptop so you can test like how your operator you are developing performs.

how is it different than `kind` ?

`kind` is like `minikube` but using docker containers instead of VMs, but as the page says "was primarily designed for testing Kubernetes itself".

(Disclaimer: I haven't looked too much into this tool other than a cursory glance)

It seems this tool isn't meant mostly for testing how different components behave under different scenarios and/or load. This is probably particularly helpful for custom controllers or operators. What happens to your controller if it's constantly reconciling 100k pods? What about 5k nodes? Something else? If this tool makes creating a "loaded" cluster easy, it's definitely handy. Would have saved me some time doing something similar a few months ago.
