The short version

  • Each has a real cost: Microsoft Azure API Management prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales; Formance formance holds no money and provides no regulatory cover, so it must be paired with a payments provider or bank, and buyers occasionally mistake a ledger for a treasury system and discover the gap late.
  • They diverge on capability: Microsoft Azure API Management covers API Gateway, Formance covers Double-entry ledger.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Azure API Management

  • Prices are not shown on the pricing page itself; every tier renders as a placeholder and routes to the calculator or sales
  • Two parallel generations of tiers, classic and v2, so the choice is which lineage before which size
  • The Developer tier is explicitly not for production
  • Self-hosted gateways and workspace gateways are charged separately from the service

Formance

  • Formance holds no money and provides no regulatory cover, so it must be paired with a payments provider or bank, and buyers occasionally mistake a ledger for a treasury system and discover the gap late.
  • Numscript is a domain-specific language your team must learn, and while it makes complex splits expressible it also means transaction logic sits outside the languages your engineers already debug well.
  • Self-hosting a ledger that must never lose or duplicate a transaction is a serious operational commitment covering backups, upgrades and Postgres tuning, which is real cost the zero licence fee hides.
  • Enterprise pricing is not published, so the difference between the free path and the supported path cannot be evaluated without a sales conversation.
  • The company is much smaller than the incumbent alternatives, and while the MIT licence protects the code it does not protect the roadmap, so features on the hosted side may arrive slowly or change direction.
