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.; Episode Six deployment on premise or in a private tenancy means the institution carries infrastructure, upgrade and PCI scope work that a hosted processor would absorb.
  • They diverge on capability: Convoy covers Inbound and outbound, Episode Six covers Tritium API platform.
  • 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.

Episode Six

  • Deployment on premise or in a private tenancy means the institution carries infrastructure, upgrade and PCI scope work that a hosted processor would absorb.
  • Implementation runs to quarters and involves core banking, network certification and fraud system integration, so time to first card is far longer than with a self serve issuer processor.
  • Pricing is entirely bespoke and weighted to large programmes, which prices out fintechs and small issuers who would be better served by a hosted platform.
  • Being smaller than the incumbent processors, its network certifications and operational presence vary by region, so a global rollout can find gaps in specific markets.
  • The flexibility of six hundred APIs and a configurable product engine shifts design responsibility onto the buyer, and institutions without strong internal payments architects end up dependent on professional services.
