The short version

  • Only GraphQL Playground has a free tier, so it costs nothing to try first.
  • Each has a real cost: GraphQL Playground apollo's own documentation states GraphQL Playground is officially retired and no longer recommended, directing users to Apollo Sandbox instead; 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.
  • They diverge on capability: GraphQL Playground covers Query building, Paymentology covers Global issuer processing.
  • 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.

GraphQL Playground

  • Apollo's own documentation states GraphQL Playground is officially retired and no longer recommended, directing users to Apollo Sandbox instead

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.

Per transaction and per active card, with a monthly minimum. Dormant cards still cost, so model your activation rate.

GraphQL Playground: What is the cost structure for Apollo GraphQL's paid plans?

Apollo uses volume-based tiered pricing for requests: first 250M operations cost $5.00 per million plus $2.00 for performance add-on; next 750M operations are $4.25 per million plus $1.50 add-on; additional tiers scale down to $3.00 per million plus $0.50 add-on for operations over 5 billion.

Paymentology: Why choose it over a United States issuer processor?

Network certification and live programmes in markets where those processors do not operate, which decides feasibility rather than preference.
