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.; Temenos Transact the codebase originates in the 1990s, so banks on older releases face major upgrade programmes to reach current versions, and many defer them for years.
  • They diverge on capability: Convoy covers Inbound and outbound, Temenos Transact covers Country model banks.
  • 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.

Temenos Transact

  • The codebase originates in the 1990s, so banks on older releases face major upgrade programmes to reach current versions, and many defer them for years.
  • Total cost is dominated by implementation partner fees rather than licence, and those programmes routinely overrun their original estimates.
  • Product changes that cloud-native cores treat as configuration can require development work and a release cycle, which slows time to market for new products.
  • Heavy customisation is common and it makes every subsequent upgrade harder, creating a compounding cost that banks feel a decade after go-live.
  • Temenos has repeatedly restructured its product line and naming, so buyers must check carefully which components a proposal actually includes and which are separately licensed.
