What's the differences from rancher?

[pst]

Rancher doesn’t generate Terraform code. It further doesn’t have a platform of multiple clusters as it’s core concept. And as a result it can’t provide the same preview, validate and promote GitOps workflow.

Last, Kubestack is native AKS, EKS or GKE. There is no meta control plane in between, like with Rancher.
