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.; Treasury Prime a fintech cannot buy Treasury Prime directly since the 2024 pivot, so the sales process starts with finding a sponsor bank willing to take your programme, which adds months and removes most of your negotiating leverage on fees.
  • They diverge on capability: Convoy covers Inbound and outbound, Treasury Prime covers BankOS.
  • Prices and features above were last checked on 31 August 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 Treasury Prime
  • A high-volume platform for which per-message webhook pricing costs more than the flat premium licencenot Treasury Prime
  • A team that also receives webhooks from many providers and wants ingestion, verification and deduplication in the same gatewaynot Treasury Prime
  • An engineering group that wants webhook delivery driven directly from an existing Kafka or SQS topicnot Treasury Prime

Treasury Prime

  • A community or regional bank that wants to run an embedded finance line with examiner-acceptable oversight of its fintech programmesnot Convoy
  • A fintech that has already chosen its sponsor bank and needs API access to that bank rather than to a middleware layernot Convoy
  • A company that wants deposits spread across several banks for FDIC coverage beyond a single institution limitnot Convoy
  • A bank replacing a fragile middleware arrangement with a structure where it holds the customer contract and the oversight obligationnot 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.

Treasury Prime

  • A fintech cannot buy Treasury Prime directly since the 2024 pivot, so the sales process starts with finding a sponsor bank willing to take your programme, which adds months and removes most of your negotiating leverage on fees.
  • Commercial terms including minimum deposit balances, reserve requirements and per transaction pricing are set by the bank rather than the platform, so two fintechs on the same software can face materially different economics with no public benchmark.
  • The company cut roughly half its staff in the 2024 pivot, which reduced the teams that supported fintech customers directly and left fintechs relying on their bank for support rather than on the vendor who wrote the software.
  • Bank risk appetite is now the binding constraint, and after the Synapse failure sponsor banks decline programmes in higher risk categories that a middleware provider would once have onboarded, so some business models simply cannot get placed.
  • If your sponsor bank exits the programme or is told by its regulator to reduce fintech exposure, you are migrating your entire deposit base to another institution, and the software being the same at both ends does not make that a small project.

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.

Treasury Prime: Can a fintech buy Treasury Prime directly?

No. Since the 2024 pivot it sells to banks. A fintech contracts with a sponsor bank running BankOS, and the bank sets the terms.

Convoy: What does premium cost?

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

Treasury Prime: Why did it change model?

Regulatory pressure on the tri-party middleware structure, sharpened by the Synapse failure. Examiners want the bank holding the customer contract and the oversight obligation, which is what bank-direct means.

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.

Treasury Prime: What is OneKey Banking?

A way of spreading deposits across several banks in the network, used for FDIC coverage above a single institution limit and for resilience if one bank exits.

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.

Treasury Prime: Is pricing published?

No, at neither the bank nor the fintech level. Fintech economics are set by the sponsor bank, so expect wide variation.
