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.
