The short version

  • Only kind has a free tier, so it costs nothing to try first.
  • Each has a real cost: kind requires Docker or Podman, so it inherits whatever container runtime limitations exist on the host; Portworx bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.
  • They diverge on capability: kind covers Nodes as containers, Portworx covers Container-native volumes.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

kind

  • Requires Docker or Podman, so it inherits whatever container runtime limitations exist on the host
  • Fewer conveniences than minikube: no addon system, so ingress and metrics need manual installation
  • Because nodes are containers sharing the host kernel, it is a weaker simulation of real node behaviour and storage

Portworx

  • Bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.
  • A 1,000 node hour monthly minimum applies, which means small or intermittent clusters pay for capacity they do not consume.
  • Replicating volumes across nodes consumes real capacity and network bandwidth, so the underlying infrastructure cost rises alongside the licence in a way the node hour rate does not show.
  • Pure Storage ownership means roadmap priorities are set by an array vendor, and buyers should confirm that hardware independence remains contractual rather than assumed.
  • Operating it well requires Kubernetes storage expertise, and teams that adopted Kubernetes to simplify operations often find they have added a distributed storage system to run.

Answered from the vendors’ own pages

kind: Is kind free?

Yes, open source and maintained under Kubernetes SIGs.

Portworx: Is Portworx tied to Pure Storage hardware?

No. It runs on any Kubernetes distribution over any underlying storage, though Pure has owned it since 2020 and sets the roadmap.

kind: Why run Kubernetes nodes as containers?

Speed and cost. A container node starts in seconds and uses far less memory than a virtual machine, which is what makes per-CI-run clusters realistic.

Portworx: What does a real cluster cost?

At 0.33 USD per virtual node hour, twenty nodes running continuously is roughly 4,800 USD a month. Bare metal at 1.11 USD per node hour is around 16,000 USD for the same node count.

kind: Is kind suitable for production?

No. It is a development and testing tool, and node isolation is weaker than real nodes because containers share the host kernel.

Portworx: Is backup included?

No. Portworx Backup is a separately priced product covering Kubernetes application backup.
