The short version

  • Only Kong Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kong Gateway the free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.; Q2 Digital Banking contracts are multi-year and priced per user or account, so a bank whose digital adoption grows faster than its revenue sees costs rise ahead of the benefit.
  • They diverge on capability: Kong Gateway covers API request routing, Q2 Digital Banking covers Retail digital banking.
  • 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.

Kong Gateway

  • The free open-source gateway lacks the analytics, portals, and support of the paid Konnect tiers.
  • Plus tier caps API requests at 1M/month before incurring per-million overage charges.
  • Enterprise pricing is custom and not published, making budgeting harder without sales contact.
  • Configuration and plugin management can require significant operational expertise to run at scale.

Q2 Digital Banking

  • Contracts are multi-year and priced per user or account, so a bank whose digital adoption grows faster than its revenue sees costs rise ahead of the benefit.
  • It is a channel layer, not a core, so any limitation in the underlying core banking system remains and integration work sits with the bank.
  • Implementations are long and consume scarce internal technology capacity at institutions that typically have very small IT teams.
  • Marketplace applications carry separate third-party contracts and fees, so the extensibility that justifies the purchase adds cost rather than being included.
  • It is US-only, and its assumptions about payment rails, regulation and account structures do not transfer to institutions outside the United States.
