The short version

  • Only Doppler has a free tier, so it costs nothing to try first.
  • Each has a real cost: Doppler developer tier limited to 3 free users with per-user fees beyond that; 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: Doppler covers Secrets management, 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.

Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that
  • Team plan pricing ($21/user/mo) adds cost for large teams
  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

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

Doppler: Do AI agents count toward my user limit?

No, AI agents and non-human identities receive free access across all Doppler plans, including Developer, Team, and Enterprise.

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.

Doppler: What is the difference between Team and Enterprise plans?

Team plan ($21/user/mo) includes SAML SSO, role-based access controls, and 90-day logs. Enterprise adds custom deployment options, unlimited config syncs, 99.95% SLA, and a dedicated account manager.

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.

Doppler: Can I rotate secrets automatically?

Yes, both Team and Enterprise plans support automatic secret rotation. Developer tier supports manual rotation only.

Source
Portworx: Is backup included?

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