The short version

  • Only Zeplo 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.; Zeplo zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • They diverge on capability: Backbase covers Digital banking front end, Zeplo covers URL prefix interface.
  • 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.

Zeplo

  • Zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
  • The free Developer tier includes only 500 requests a month and one team member, so it is a demonstration allowance rather than a usable free plan for anything real.
  • Overage on the Developer tier is 20 US dollars per 100,000 requests, two hundred times the marginal rate on the Company tier, so exceeding the free allowance without upgrading is expensive.
  • Team members cost 15 US dollars each beyond the plan allowance, which is an odd charge on an infrastructure product billed by request volume.
  • Log retention is 30 days on both published tiers, so anything requiring longer audit trails on job execution has to be logged separately.
