The short version

  • Each has a real cost: Nomad nomad 1.7.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence; OpenEBS there is no vendor on the other end of an incident unless you separately contract DataCore, so an outage at three in the morning is resolved by your own team and a public Slack channel.
  • They diverge on capability: Nomad covers Container orchestration, OpenEBS covers Replicated engine.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Nomad

  • Multi-region application deploymentnot OpenEBS
  • Flexible scheduling for batch jobs and servicesnot OpenEBS

OpenEBS

  • Running Cassandra or Kafka on Kubernetes where the application already replicates and node-local volumes are sufficientnot Nomad
  • A platform team that needs persistent volumes on bare metal Kubernetes without a per node subscriptionnot Nomad
  • An edge or lab deployment where a commercial storage licence cannot be justifiednot Nomad
  • Replacing hostpath volumes with something that has snapshots and a Container Storage Interface drivernot Nomad

Where each one falls short

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

Nomad

  • Nomad 1.7.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Nomad to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions
  • Each version converts to MPL 2.0 only four years after that version is published
  • Resource quotas, Sentinel policies and audit logging sit in a Governance and Policy add-on module that is separate from the Enterprise base platform package
  • Multi-region deployments, multiple Vault namespaces and Nomad Autopilot advanced server management require Nomad Enterprise

OpenEBS

  • There is no vendor on the other end of an incident unless you separately contract DataCore, so an outage at three in the morning is resolved by your own team and a public Slack channel.
  • The project has several storage engines with different maturity and different operational characteristics, and choosing the wrong one for your workload produces poor results that look like a product failure.
  • Documentation and upgrade guidance assume real Kubernetes storage knowledge, so teams without that expertise underestimate the operational load they are taking on.
  • Project governance shifted after DataCore acquired MayaData in 2021, which means the direction of a supposedly neutral project is influenced by one commercial sponsor.
  • Disaster recovery, cross-cluster replication and policy-driven data services are thinner than in the commercial alternatives, so organisations with those requirements end up building them or buying a product anyway.

Answered from the vendors’ own pages

Nomad: Is HashiCorp Nomad free?

HashiCorp Nomad is open source and free to use. Commercial enterprise support and hosting options may be available through HashiCorp, but the core product is free.

OpenEBS: Who supports it in production?

The project is community supported. Commercial support is available from DataCore, which acquired the original sponsor MayaData in 2021. Establish that relationship before production, not during an incident.

Nomad: Does HashiCorp Nomad have a pricing model?

Nomad is open source software with no published pricing tiers. HashiCorp offers commercial hosting and support for their products on a usage-based or custom pricing model, but Nomad itself is free to download and deploy.

OpenEBS: Which engine should we use?

If your application replicates its own data, use a Local engine and avoid replicating twice. If it does not, such as with PostgreSQL, use the Replicated engine.

Nomad: What is HashiCorp's pricing model for enterprise Nomad?

HashiCorp offers flexible pricing for enterprise Nomad support including pay-as-you-go (PAYG) billing with no long-term commitment, flex plans with preferred pricing, and enterprise self-managed plans. Contact HashiCorp sales for custom quotes.
