The short version

  • Only KeystoneJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: Backbase pricing scales with assets under management and AI API calls, meaning cost grows as the bank itself grows and adopts more AI features, which is a less predictable cost curve than a flat per-seat model.; KeystoneJS database support is limited to PostgreSQL, MySQL and SQLite
  • They diverge on capability: Backbase covers Digital banking front end, KeystoneJS covers REST API.
  • 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.

Backbase

  • Pricing scales with assets under management and AI API calls, meaning cost grows as the bank itself grows and adopts more AI features, which is a less predictable cost curve than a flat per-seat model.
  • It sits above, not instead of, a core banking system, so adopting it does not reduce a bank's overall vendor count or technology complexity; it adds a specialised layer.
  • As with any customer-facing banking platform, an outage or performance issue directly affects the bank's customers, so the operational stakes of vendor reliability are high.
  • Implementation for a large bank spans multiple modules and integration points, and realistic timelines run well beyond a simple software rollout.
  • Pricing opacity means a bank cannot benchmark Backbase against competing engagement banking platforms without engaging each vendor's own sales process separately.

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
