The short version

  • Only Formance has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apigee the free evaluation is a sandbox limited to 60 days; 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: Apigee 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.

Apigee

  • The free evaluation is a sandbox limited to 60 days
  • Pay-as-you-go has no SLA available at all
  • Pay-as-you-go bills environments separately from API calls, with a Base environment costing $365 per month per region
  • The Base environment is capped at 50 QPS with an SLA of up to 99%
  • Standard API Proxy calls are billed at $20 per 1M calls up to 50M, and Extensible API Proxy calls at $100 per 1M calls up to 50M
  • API Analytics is a paid add-on at $20 per 1M API calls and cannot be bought on a Base environment
  • Advanced API Security is a paid add-on at $350 per 1M API calls and cannot be bought on a Base environment
  • Monetization is unavailable on pay-as-you-go and requires a subscription tier
  • Additional API proxy deployments beyond those included cost $0.04 per hour per region on a Comprehensive environment
  • Subscription tiers Standard, Enterprise and Enterprise Plus are quote only with no published price
  • Google Cloud networking charges for IP addresses, data transfer out and forwarding rules are billed on top of Apigee usage

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.
