The short version
- Only Yapily has a free tier, so it costs nothing to try first.
- Each has a real cost: 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.; Yapily production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.
- They diverge on capability: Unit covers Deposit accounts, Yapily covers Unified open banking API.
- 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.
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- Pricing is unpublished and blends platform fees, per-account and per-transaction charges and interchange sharing, which makes it hard to model unit economics before you have volume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.
Yapily
- Production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.
- Consumer adoption of pay-by-bank still lags card payments, so merchants offering it as a checkout option typically see it used as a secondary rather than primary payment method.
- Coverage depends on the banks in each country maintaining reliable open banking APIs, and inconsistent bank-side reliability across markets is a known category-wide weakness, not unique to Yapily but not solved by it either.
- As infrastructure for both account data and payments, a company only needing one of those two capabilities is still evaluating a broader platform than it may need.
- Regulatory dependence on PSD2 and UK open banking rules means the underlying legal framework, not just Yapily's product, could shift and affect what is possible on the platform.

Answered from the vendors’ own pages
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.
Yapily: Is there a free way to try it?
Yes, sandbox access is free for development and testing.
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.
Yapily: How much cheaper is pay-by-bank than card payments?
Typically 0.1 to 0.5% of transaction value, or a flat 5 to 30 pence, against 1.5 to 3.5% for card scheme fees.
Unit: What does Unit cost?
Not published. Expect a platform fee, per-account and per-transaction charges, an interchange share and a minimum commitment.
Yapily: Is production pricing published?
No, production access is pay-as-you-go but exact rates require a sales conversation.
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.
