The short version

  • Only Spring Cloud Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: Spring Cloud Gateway released under the Apache 2.0 license, free and open source with no commercial tier; 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: Spring Cloud Gateway covers Routing, Treasury Prime covers BankOS.
  • Prices and features above were last checked on 31 August 2026.

Treasury Prime

  • A fintech that has already chosen its sponsor bank and needs API access to that bank rather than to a middleware layernot Spring Cloud Gateway

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Spring Cloud Gateway

  • Released under the Apache 2.0 license, free and open source with no commercial tier

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.

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

Spring Cloud Gateway: What enterprise support is available for Spring Cloud Gateway?

Tanzu Spring provides optional enterprise support including Day 0 access to security patches for organizations requiring guaranteed support, but specific pricing is not published on the Spring Cloud Gateway project page.

Source
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.

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.

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.
