The short version
- Each has a real cost: Astra push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.; 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.
- They diverge on capability: Astra covers Instant disbursements, Salt Edge covers Account information.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Astra
- Push-to-card costs materially more per transaction than ACH, so a platform that switches all payouts to instant sees payment costs rise sharply, and the usual answer of charging the recipient for speed only works where recipients will pay.
- Original Credit Transaction support is not universal across card issuers, so a proportion of payouts fall back to slower rails and you must build and explain a two speed experience rather than promising instant to everyone.
- The programme depends on Cross River Bank as sponsor, a bank with concentrated fintech exposure and a documented regulatory history, so a single supervisory action on that institution is a direct operational risk to your payouts.
- Nothing is published on pricing, and per transaction economics vary by rail and volume, so small platforms cannot estimate cost before a sales conversation and have limited leverage in it.
- FedNow reach still depends on the recipient bank participating, so instant account-to-account is not available to every recipient and the routing logic has to degrade gracefully, which is more integration work than the single API framing suggests.
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.

Answered from the vendors’ own pages
Astra: Who is the sponsor bank?
Cross River Bank. All banking and payment services run through that relationship, so the bank should be part of your diligence rather than an implementation detail.
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.
Astra: Do I have to prefund payouts?
Not necessarily. Astra offers a net debit arrangement where disbursements settle against a reserve rather than a permanently funded float account, which is the main working capital argument for the product.
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.
Astra: Is every payout instant?
No. Push-to-card requires the recipient card issuer to support Original Credit Transactions, and FedNow requires the recipient bank to participate. The rest fall back to ACH.
Salt Edge: Does it do payments as well as data?
Yes, payment initiation is supported in European markets where PSD2 applies.
Astra: What does it cost?
Nothing is published. Pricing is per transaction and varies by rail and volume, and card rails cost considerably more than ACH.
Salt Edge: What does it cost?
Not published. Pricing is usage-based and quoted, though the sandbox is free.
