The short version

  • Only PubNub has a free tier, so it costs nothing to try first.
  • 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.; PubNub free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • They diverge on capability: Paymentology covers Global issuer processing, PubNub covers Pub/sub messaging.
  • 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.

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.

PubNub

  • Free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • MAU-based pricing means costs scale directly with user growth, which can be less predictable than flat message-based pricing.
  • Pro-tier custom pricing above 50,000 MAU requires contacting sales rather than self-serve checkout.

Answered from the vendors’ own pages

Paymentology: Does Paymentology provide the BIN and licence?

No. You need your own issuing licence or a sponsor bank in each market; Paymentology processes the transactions.

PubNub: What does PubNub cost?

PubNub offers a free plan for up to 200 MAU or 1 million transactions, a Starter plan at $98/month for 1,000 MAU, and custom Pro pricing for larger volumes, e.g. around $550/month for 10,000 MAU.

Paymentology: What is the actual pricing model?

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

PubNub: Is there a free plan, and what are its limits?

Yes, the free plan supports up to 200 monthly active users or 1 million transactions, includes 1GB of data storage retained for 7 days, and requires no credit card.

Source
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.

PubNub: How is usage metered?

PubNub bills primarily by Monthly Active Users, defined as a unique user who connects at least once in a billing cycle; messages are bundled into MAU pricing with no separate per-message fees, and overage is billed proportionally.
