Yep that's right, we do not require k8s. There's a ton of existing infrastructure into k8s so we try to make it apparent how you integrate there. The local CLI, wash, is an example of how we run locally, it's just a Windows/Mac/Linux binary and then the WebAssembly components are architecture/OS agnostic.

We use NATS to connect distributed hosts and manage distributed state (e.g. no etcd) so as long as you can connect the NATS servers you can run anywhere.
