The short version

  • Each has a real cost: Apigee the free evaluation is a sandbox limited to 60 days; Temenos Transact the codebase originates in the 1990s, so banks on older releases face major upgrade programmes to reach current versions, and many defer them for years.
  • They diverge on capability: Apigee covers API Gateway, Temenos Transact covers Country model banks.
  • 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.

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

Temenos Transact

  • The codebase originates in the 1990s, so banks on older releases face major upgrade programmes to reach current versions, and many defer them for years.
  • Total cost is dominated by implementation partner fees rather than licence, and those programmes routinely overrun their original estimates.
  • Product changes that cloud-native cores treat as configuration can require development work and a release cycle, which slows time to market for new products.
  • Heavy customisation is common and it makes every subsequent upgrade harder, creating a compounding cost that banks feel a decade after go-live.
  • Temenos has repeatedly restructured its product line and naming, so buyers must check carefully which components a proposal actually includes and which are separately licensed.
