The short version

  • Only Convoy has a free tier, so it costs nothing to try first.
  • 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.; Ozone API it provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • They diverge on capability: Convoy covers Inbound and outbound, Ozone API covers Multi-standard support.
  • 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.

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.

Ozone API

  • It provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • Value is driven by regulatory obligation, so an institution not under a mandate struggles to build a business case for the spend.
  • It is a small UK vendor selling to large regulated institutions, which raises procurement and vendor viability questions during bank due diligence.
  • Premium API monetisation is a genuine capability but few banks have found real demand, so revenue projections used to justify the purchase often do not materialise.
  • Standards evolve continuously and each revision means a change programme in your own systems, even where Ozone absorbs the specification work at the API edge.

Ozone API: Which standards does it support?

UK Open Banking, Berlin Group, FDX, Consumer Data Right and Gulf regional standards, among others, from one platform.
