Independent open banking aggregator covering Europe by PSD2 API and other markets by direct connection

The short version
- Only Prisma has a free tier, so it costs nothing to try first.
- Each has a real cost: Prisma prisma Postgres is billed per operation, with the free tier at 100,000 operations and 500 MB of storage; 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: Prisma covers ORM, Salt Edge covers Account information.
- Prices and features above were last checked on 31 August 2026.

- A bank that must publish PSD2-compliant APIs and would rather buy the compliance layer than build itnot Prisma
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Prisma
- Prisma Postgres is billed per operation, with the free tier at 100,000 operations and 500 MB of storage
- Starter at $10 a month includes 1M operations then charges $0.0080 per 1,000
- Storage overage runs from $2.00 per GB on Starter down to $1.00 per GB on Business, so the unit cost depends on the plan
- Accelerate charges separately per operation and per GiB of query egress beyond the first 1 KiB
- Cache tag invalidations are not included below the Pro plan and are billed per thousand above it
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
Prisma: How much does Prisma cost?
Prisma is free to start with 1M requests/month. The Starter plan costs $10/month with 5M requests, the Pro plan $49/month with 20M requests, and the Business plan $129/month with 100M requests. All plans have usage-based overages.
SourceSalt 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.
Prisma: What is Prisma's overage pricing?
Prisma charges $1 per million requests over the included amount (Starter), $2 per million database operations overage (Pro and Starter), and $1.50-$2 per GB for storage overages depending on the plan. All plans include a hard spend limit on by default.
SourceSalt 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.
Prisma: Does Prisma include data transfer costs?
No, Prisma includes unlimited data transfer with no egress fees on all plans. Prisma ORM remains free across all tiers.
SourceSalt Edge: Does it do payments as well as data?
Yes, payment initiation is supported in European markets where PSD2 applies.
Salt Edge: What does it cost?
Not published. Pricing is usage-based and quoted, though the sandbox is free.
