The short version

  • Only Buildkite has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildkite free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention; 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.

Portworx

  • A platform team offering self-service databases to developers on an internal Kubernetes platformnot Buildkite

  • An OpenShift estate where the built-in storage option does not meet the availability requirement for stateful setsnot Buildkite

Where each one falls short

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

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac

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

Buildkite: Can I use Buildkite without paying?

Yes, Buildkite offers a free plan that includes up to 5 users, 10 concurrent jobs, 2000 Linux vCPU minutes monthly, and 250k test executions per month at no cost.

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.

Buildkite: What happens if I exceed my included compute minutes on Buildkite?

Hosted agent compute is charged separately at $0.004 per Linux vCPU minute and $0.02 per Mac vCPU minute, billed to the second with no minimums.

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.

Buildkite: Do I need an annual commitment for Buildkite's Pro plan?

No, Buildkite's Pro plan is billed monthly at $30 per active user with no long-term contract required. All tiers include a 30-day all-access trial.

Source
Portworx: Is backup included?

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

Buildkite: What user limits apply to each Buildkite plan?

Free plan supports up to 5 users, Pro plan supports up to 50 users, and Enterprise plan provides unlimited users with a 30-user minimum.
