The short version

  • Only Yapily has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mambu pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.; 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.
  • They diverge on capability: Mambu covers Composable engine architecture, Yapily covers Unified open banking 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.

Mambu

  • Pricing is entirely unpublished, and as subscription and usage-based fees scale with a bank's book of business, total cost at scale is hard to forecast before a detailed vendor conversation.
  • A core banking implementation is a multi-year, high-switching-cost commitment regardless of vendor, and Mambu is no exception; a wrong initial configuration choice is expensive to unwind.
  • Composability is a genuine strength but also means more integration and configuration decisions fall to the bank's own team or system integrator, versus a more opinionated, less flexible fixed-core alternative.
  • As cloud-hosted core banking infrastructure, a bank is trusting Mambu's own uptime and security posture for its most business-critical system, concentrating operational risk in one vendor relationship.
  • Newer entrants such as Thought Machine and 10x Banking compete directly on similar composable positioning, so Mambu's tenure advantage is real but narrowing as competitors mature.

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.
