The short version

  • Only PubNub has a free tier, so it costs nothing to try first.
  • Each has a real cost: Method Financial institution coverage is uneven once you move beyond major card issuers, so a lender focused on auto or student loan servicers should test its own portfolio mix rather than trust the headline institution count.; PubNub free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • They diverge on capability: Method Financial covers Identity-based account resolution, PubNub covers Pub/sub messaging.
  • 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.

Method Financial

  • Institution coverage is uneven once you move beyond major card issuers, so a lender focused on auto or student loan servicers should test its own portfolio mix rather than trust the headline institution count.
  • It reads liabilities, not cash flow, so a lender that also needs income and affordability evidence is running a second aggregator alongside it and paying twice for consumer connectivity.
  • Payoff quote accuracy and freshness are commercially load bearing, because a consolidation loan funded against a stale figure leaves a residual balance and a customer complaint, and the contractual position on that risk needs to be explicit.
  • Pricing is unpublished and split across data and payment events, which makes unit economics hard to model before volume and easy to misjudge in a product where every application triggers multiple calls.
  • Identity-based access without credentials depends on consumer consent capture being defensible, and any shift in US regulatory interpretation of permissioned data access lands directly on this model rather than on the edges of it.

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

Method Financial: How is this different from Plaid?

Plaid connects to deposit accounts with credentials and returns transactions. Method resolves liabilities from verified identity without credentials and can pay those accounts directly. Most lenders use both.

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.

Source
Method Financial: Do consumers have to log in to each card issuer?

No. That is the point of the product, and removing that step is what changes conversion in consolidation and refinancing flows.

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
Method Financial: What does it cost?

Not published. It is quoted by volume and split across liability data, payoff quotes and payment execution.

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
Method Financial: Can it actually pay off a credit card?

Yes, funds are sent directly to the identified card accounts, which is what makes balance transfer and consolidation products work without account numbers.
