The short version

  • Only Crossplane has a free tier, so it costs nothing to try first.
  • Each has a real cost: Crossplane requires Kubernetes expertise and infrastructure; 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: Crossplane covers Kubernetes extension, Portworx covers Container-native volumes.
  • Prices and features above were last checked on 1 September 2026.

Crossplane

  • Creating unified control layers for multi-cloud infrastructurenot Portworx
  • Designing declarative APIs for infrastructure provisioningnot Portworx

Portworx

  • Running a production PostgreSQL or Cassandra cluster on Kubernetes and needing the data to survive node lossnot Crossplane
  • A platform team offering self-service databases to developers on an internal Kubernetes platformnot Crossplane
  • Failing over stateful applications between clusters in different regions as a disaster recovery positionnot Crossplane
  • An OpenShift estate where the built-in storage option does not meet the availability requirement for stateful setsnot Crossplane

Where each one falls short

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

Crossplane

  • Requires Kubernetes expertise and infrastructure
  • Steep learning curve for teams new to Kubernetes patterns
  • Provider ecosystem smaller than Terraform

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

Crossplane: Is Crossplane free?

Yes, Crossplane is open source and free to use. It requires a Kubernetes cluster but has no licensing costs.

Source
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.

Crossplane: What is Crossplane used for?

Crossplane is used to build control planes and platforms for infrastructure management, enabling platform teams to expose safe APIs to other teams.

Source
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.

Portworx: Is backup included?

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