The short version

  • Each has a real cost: Yapily production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.; 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: Yapily covers Unified open banking API, 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.

Yapily

  • Production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.
  • Consumer adoption of pay-by-bank still lags card payments, so merchants offering it as a checkout option typically see it used as a secondary rather than primary payment method.
  • Coverage depends on the banks in each country maintaining reliable open banking APIs, and inconsistent bank-side reliability across markets is a known category-wide weakness, not unique to Yapily but not solved by it either.
  • As infrastructure for both account data and payments, a company only needing one of those two capabilities is still evaluating a broader platform than it may need.
  • Regulatory dependence on PSD2 and UK open banking rules means the underlying legal framework, not just Yapily's product, could shift and affect what is possible on the platform.

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.

Typically 0.1 to 0.5% of transaction value, or a flat 5 to 30 pence, against 1.5 to 3.5% for card scheme fees.
