The short version

  • Each has a real cost: Salt Edge coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.; Unit your product depends on a sponsor bank you do not contract with directly, and 2024 showed what that means: Thread Bank received an FDIC enforcement action naming its banking as a service programmes and Blue Ridge Bank went under an OCC consent order and offboarded fintech partners.
  • They diverge on capability: Salt Edge covers Account information, Unit covers Deposit accounts.
  • 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.

Salt Edge

  • Coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.
  • Pricing is not published and is usage-based, so two providers cannot be compared without running both sales processes, and cost grows with the connected user base rather than with revenue.
  • Support and engineering are distributed across Eastern Europe and Canada, and buyers in other time zones report slower turnaround on connection-specific breakages than they get from a domestic provider.
  • PSD2 consent rules require customers to reauthenticate periodically, and Salt Edge cannot change that, so any product depending on continuous data must design for consent expiry and the drop-off it causes.
  • United States coverage is weaker than Plaid or Mastercard Open Banking, so a company with meaningful US volume ends up running two aggregators and normalising between them.

Unit

  • Your product depends on a sponsor bank you do not contract with directly, and 2024 showed what that means: Thread Bank received an FDIC enforcement action naming its banking as a service programmes and Blue Ridge Bank went under an OCC consent order and offboarded fintech partners.
  • Programme approval by the bank is a separate gate from signing with Unit, and it can add months and impose product restrictions that were not visible during the commercial conversation.
  • Compliance obligations are shared but the operational load lands on you, and platforms consistently underestimate the staffing needed for disputes, escalations and the bank ongoing oversight requests.
  • Pricing is unpublished and blends platform fees, per-account and per-transaction charges and interchange sharing, which makes it hard to model unit economics before you have volume and easy to be surprised by the minimum.
  • Migrating a live deposit programme to a different provider or bank is extremely disruptive because it involves moving customer accounts and card credentials, so switching costs are far higher than for ordinary software.

Answered from the vendors’ own pages

Salt Edge: Who owns Salt Edge?

It is independently owned, unlike Tink (Visa), Finicity (Mastercard) or Yodlee (Envestnet), which matters if your use case competes with the owner.

Unit: Who actually holds the money?

A chartered partner bank, not Unit. Deposits sit at the sponsor bank and FDIC insurance flows from that bank, so its condition is your condition.

Salt Edge: Is all coverage direct bank API?

No. Inside PSD2 markets connections use regulated APIs; elsewhere coverage relies on direct connections whose reliability depends on the bank not changing its systems. Ask for a per-institution answer.

Unit: What happened with Unit sponsor banks in 2024?

Thread Bank received an FDIC enforcement action that explicitly named its banking as a service and lending as a service programmes, and Blue Ridge Bank was under an OCC consent order from January 2024 and offboarded fintech partners. Blue Ridge exited the order in late 2025.

Salt Edge: Does it do payments as well as data?

Yes, payment initiation is supported in European markets where PSD2 applies.

Unit: What does Unit cost?

Not published. Expect a platform fee, per-account and per-transaction charges, an interchange share and a minimum commitment.

Salt Edge: What does it cost?

Not published. Pricing is usage-based and quoted, though the sandbox is free.

Unit: Do we need our own compliance team?

Yes. Unit supplies tooling and the bank sets the rules, but disputes, escalations and evidence for bank oversight require named people on your side.
