Where each one falls short

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

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.

Stoplight

  • The free plan allows one project and one user
  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually
  • SSO and shared style guides are Pro Team only, at $362 a month billed annually
  • Seats beyond each plan's allowance are $11 to $27 each per month depending on tier and billing period
