The short version

  • Only KeystoneJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: KeystoneJS database support is limited to PostgreSQL, MySQL and SQLite; 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: KeystoneJS covers REST API, 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.

KeystoneJS

  • Database support is limited to PostgreSQL, MySQL and SQLite
  • Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
  • Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
  • Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

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.
