The short version

  • Each has a real cost: Appwrite smaller ecosystem compared to Firebase; fewer third-party integrations and extensions; 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: Appwrite covers REST API, 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.

Appwrite

  • Smaller ecosystem compared to Firebase; fewer third-party integrations and extensions
  • Analytics, crash reporting, and A/B testing not included (Firebase includes these)
  • Requires infrastructure management for self-hosted deployments; not fully managed like Firebase Cloud
  • Mobile app support not as mature as Firebase's native iOS/Android SDKs

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.
