The short version

  • Each has a real cost: 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.; WSO2 API Manager the free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • They diverge on capability: OpenEBS covers Replicated engine, WSO2 API Manager covers API Gateway.
  • 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.

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.

WSO2 API Manager

  • The free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • A commercial production licence is not part of the free download and comes only with a subscription
  • No subscription price is published; Basic Support and Enterprise Support both require contacting sales for a quote
  • 24x7x365 coverage requires Enterprise Support; the general query SLA is one business day
  • A Customer Success Manager is a paid optional add on covering business hours only
  • Consulting services and WSO2 Private Cloud hosting are quoted separately

Answered from the vendors’ own pages

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.

WSO2 API Manager: How is WSO2 API Manager priced?

WSO2 API Manager pricing is not published on their website. As an enterprise API management platform, pricing is custom-quoted based on deployment model and organizational requirements.

Source
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.

WSO2 API Manager: Does WSO2 API Manager offer different pricing for on-premises versus cloud deployments?

WSO2 API Manager supports multiple deployment options including on-premises and cloud, but pricing structures for different deployment models are not publicly disclosed.

Source
OpenEBS: Does it cost anything?

No licence fee. The cost is operational, and a support contract if you want someone accountable.

WSO2 API Manager: What deployment flexibility does WSO2 API Manager provide?

WSO2 API Manager enables flexible deployment on-premises or in cloud environments, but specific pricing tiers for each deployment model require contacting WSO2 sales.

Source
WSO2 API Manager: How would I request a WSO2 API Manager pricing quote?
