The short version

  • Each has a real cost: Ozone API it provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.; 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: Ozone API covers Multi-standard support, Salt Edge covers Account information.
  • 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.

Ozone API

  • It provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • Value is driven by regulatory obligation, so an institution not under a mandate struggles to build a business case for the spend.
  • It is a small UK vendor selling to large regulated institutions, which raises procurement and vendor viability questions during bank due diligence.
  • Premium API monetisation is a genuine capability but few banks have found real demand, so revenue projections used to justify the purchase often do not materialise.
  • Standards evolve continuously and each revision means a change programme in your own systems, even where Ozone absorbs the specification work at the API edge.

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

Ozone API: Is this a competitor to Plaid or TrueLayer?

No, the opposite side. Ozone is bought by the bank exposing data; Plaid and TrueLayer consume it on behalf of third parties.

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.

Ozone API: Does it connect to my core banking system?

It provides the standards-compliant API surface and adapters, but connecting your core is an integration project you scope separately.

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.

Ozone API: Which standards does it support?

UK Open Banking, Berlin Group, FDX, Consumer Data Right and Gulf regional standards, among others, from one platform.

Salt 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.
