The short version

  • Each has a real cost: Convoy the default deployment is self-hosted, so you operate Convoy plus Postgres and Redis and carry the on-call burden for the system that delivers your customers' events.; 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: Convoy covers Inbound and outbound, 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.

Convoy

  • A fintech that cannot route customer webhook traffic through a third-party SaaS for compliance reasonsnot OpenEBS
  • A high-volume platform for which per-message webhook pricing costs more than the flat premium licencenot OpenEBS
  • A team that also receives webhooks from many providers and wants ingestion, verification and deduplication in the same gatewaynot OpenEBS
  • An engineering group that wants webhook delivery driven directly from an existing Kafka or SQS topicnot OpenEBS

OpenEBS

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

Where each one falls short

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

Convoy

  • The default deployment is self-hosted, so you operate Convoy plus Postgres and Redis and carry the on-call burden for the system that delivers your customers' events.
  • Frain Technologies is a small startup, and putting customer-facing delivery infrastructure on it means accepting real vendor continuity risk on a component that is hard to swap out quickly.
  • The premium tier at a flat 999 US dollars a month is poor value below substantial volume, while the community edition omits the portal, transformations and RBAC that most production deployments end up wanting.
  • The hosted cloud trial is capped at one project and 100 events a day, which is too small to properly evaluate the service before committing.
  • Documentation and the third-party ecosystem are thinner than the established webhook services, so unusual configurations often mean reading the Go source.

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

Convoy: Is Convoy really open source?

Yes, the community edition is open source and self-hostable, covering both inbound and outbound webhooks with retries.

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.

Convoy: What does premium cost?

A flat 999 US dollars a month, self-hosted, regardless of message volume.

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.

Convoy: Does it receive webhooks as well as send them?

Yes, inbound ingestion with verification and deduplication is a first-class feature, unlike most webhook services.

OpenEBS: Does it cost anything?

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

Convoy: Do I have to self-host?

No, there is a hosted cloud, but the trial is capped at 100 events a day and self-hosting is the primary model.
