The short version

  • Each has a real cost: Portkey the free Developer tier records only 10,000 logs per month with 3 day log retention; the $49 per month Production tier raises that to 100,000 logs with $9 per additional 100,000 requests, as of August 2026.; 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.

Where each one falls short

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

Portkey

  • The free Developer tier records only 10,000 logs per month with 3 day log retention; the $49 per month Production tier raises that to 100,000 logs with $9 per additional 100,000 requests, as of August 2026.

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.
