The short version

  • Only Spring Cloud Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: i2c developer experience lags API-native competitors, and teams expecting Stripe-grade documentation and sandboxes find an enterprise integration project instead.; Spring Cloud Gateway released under the Apache 2.0 license, free and open source with no commercial tier
  • They diverge on capability: i2c covers Configurable product engine, Spring Cloud Gateway covers Routing.
  • 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.

i2c

  • Developer experience lags API-native competitors, and teams expecting Stripe-grade documentation and sandboxes find an enterprise integration project instead.
  • Implementations lean on i2c or partner professional services, so timelines and costs are set by a services queue rather than by your own engineering speed.
  • Pricing is per active card and per transaction with monthly minimums, none of it published, so comparing bids requires modelling your own portfolio carefully.
  • Configuration flexibility means product behaviour lives in platform settings rather than in your repository, which complicates version control, testing and audit trails.
  • As a private company with a broad global footprint, regional support depth is uneven, and a programme in a smaller market may get thinner service than a flagship account.

Spring Cloud Gateway

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

Answered from the vendors’ own pages

i2c: Does i2c issue the cards itself?

No. It processes; issuance sits with a bank or licensed issuer, and in most markets you need that relationship separately.

Spring Cloud Gateway: Is Spring Cloud Gateway free?

Yes, Spring Cloud Gateway is free and open-source software. It is part of the Spring ecosystem and available through GitHub repositories with open-source dependencies like spring-cloud-starter-gateway-server-webflux and spring-cloud-starter-gateway-server-webmvc.

i2c: Can it handle revolving credit?

Yes. Credit, instalments and buy-now-pay-later sit on the same platform as debit and prepaid, which is unusual among modern processors.

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
i2c: Is it self-serve?

No. Expect a configuration-led implementation with professional services rather than signing up and calling an API.
