The short version

  • Each has a real cost: Paymentology paymentology processes but does not hold issuing licences, so every market still needs your own licence or a sponsor bank, which is usually the slowest and most expensive part of a launch.; 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.

Where each one falls short

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

Paymentology

  • Paymentology processes but does not hold issuing licences, so every market still needs your own licence or a sponsor bank, which is usually the slowest and most expensive part of a launch.
  • Fees include per active card charges and monthly minimums, so a portfolio with many dormant cards pays for plastic that generates no interchange.
  • Certification, settlement and scheme relationships differ by country, so a multi market rollout is a series of separate projects rather than one integration.
  • As a processor it sits between your product and the networks, meaning outages and scheme mandate changes reach your cardholders through a party you do not control.
  • Documentation and developer self service are weaker than the United States hosted processors, so early integration depends heavily on Paymentology implementation staff.

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.
