The short version
- Only Zeplo 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.; Zeplo zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
- They diverge on capability: Unit covers Deposit accounts, Zeplo covers URL prefix interface.
- 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.
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- Pricing is unpublished and blends platform fees, per-account and per-transaction charges and interchange sharing, which makes it hard to model unit economics before you have volume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.
Zeplo
- Zeplo sits directly in the execution path of your background work, so an outage at a very small vendor means your jobs do not run at all, and there is no published SLA below Enterprise.
- The free Developer tier includes only 500 requests a month and one team member, so it is a demonstration allowance rather than a usable free plan for anything real.
- Overage on the Developer tier is 20 US dollars per 100,000 requests, two hundred times the marginal rate on the Company tier, so exceeding the free allowance without upgrading is expensive.
- Team members cost 15 US dollars each beyond the plan allowance, which is an odd charge on an infrastructure product billed by request volume.
- Log retention is 30 days on both published tiers, so anything requiring longer audit trails on job execution has to be logged separately.

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.
Zeplo: How does Zeplo work?
You prefix your endpoint URL with zeplo.to and add query parameters for retries, delay, cron or concurrency. No SDK or broker is needed.
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.
Zeplo: What does it cost?
Free for 500 requests a month; 39 US dollars a month for a million requests, then 10 dollars per additional million.
Unit: What does Unit cost?
Not published. Expect a platform fee, per-account and per-transaction charges, an interchange share and a minimum commitment.
Zeplo: Is it suitable for critical jobs?
It is a small vendor in your execution path with no published SLA below Enterprise, so weigh that against the convenience.
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.
Zeplo: Does it work with serverless platforms?
Yes, that is its main use, covering Vercel, Cloudflare Workers, Netlify and similar environments that lack long-running workers.
