The short version

  • Only PubNub has a free tier, so it costs nothing to try first.
  • Each has a real cost: PubNub free plan storage history is limited to 7 days, which is short for apps needing longer message retention.; Synctera implementation fee, platform fee and monthly minimum are all charged and none are published, so a programme cannot model its fixed cost floor without a sales process, and at low volume those fixed fees rather than transaction pricing determine your economics.
  • They diverge on capability: PubNub covers Pub/sub messaging, Synctera covers Sponsor bank matching.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

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.

Synctera

  • Implementation fee, platform fee and monthly minimum are all charged and none are published, so a programme cannot model its fixed cost floor without a sales process, and at low volume those fixed fees rather than transaction pricing determine your economics.
  • The sponsor bank remains a third party whose risk appetite governs what you can launch, and a bank exiting or tightening its programme can force product changes you did not choose, which has happened repeatedly across the sector.
  • Onboarding runs on bank timelines, so several months typically pass between contract and first live customer while compliance policies and flow of funds are reviewed by both Synctera and the bank.
  • Coverage is United States focused, so a fintech with cross-border plans needs an entirely separate stack for other markets rather than an extension of this one.
  • Sitting between you and the bank means Synctera is another party in the reconciliation chain, and when balances disagree you are coordinating between two organisations rather than one, which lengthens incident resolution.

Source
Synctera: Does Synctera provide the bank?

Yes. Unlike a pure technology vendor, Synctera contracts with sponsor banks and brings one into your programme.

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
Synctera: What does it cost?

Nothing is published. Expect an implementation fee, a recurring platform fee and a monthly minimum, plus usage charges.

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.

Source
Synctera: How long does it take to launch?

Plan for months, not weeks, because both Synctera and the sponsor bank run compliance diligence on your programme.

Synctera: Is it available outside the United States?

Its focus is the United States; it has offered Canadian capability but non-US coverage is limited.
