The short version

  • Only Bruno has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bruno native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month; 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: Bruno covers API Testing, 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.

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

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.
