The short version

  • Only Swagger/OpenAPI has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Swagger/OpenAPI the OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it
  • They diverge on capability: Salt Edge covers Account information, Swagger/OpenAPI covers OpenAPI Specification.
  • 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.

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.

Swagger/OpenAPI

  • The OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it

Answered from the vendors’ own pages

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.

Swagger/OpenAPI: Is Swagger UI free to use?

Swagger UI is an open source tool with source code publicly available on GitHub at no cost. It is one of thousands of free open source projects in the Swagger ecosystem.

Source
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.

Swagger/OpenAPI: What commercial Swagger products are available beyond the open source tools?

Swagger offers Swagger for Teams for streamlined API workflow with interactive editors and hosted documentation, and Swagger Enterprise for organizations needing secure on-premise or cloud-based environments. Specific pricing requires contacting sales.

Source
Salt Edge: Does it do payments as well as data?

Yes, payment initiation is supported in European markets where PSD2 applies.

Swagger/OpenAPI: Are there commercial versions that build on the open source Swagger tools?

Yes, commercial Swagger products integrate the core functionality of Swagger open source tools (Editor, UI, and Codegen) with advanced capabilities for team collaboration, standards enforcement, and enterprise features.

Source
Salt Edge: What does it cost?

Not published. Pricing is usage-based and quoted, though the sandbox is free.

Swagger/OpenAPI: Is there a trial available for Swagger commercial products?

A Start Trial call-to-action is available on the Swagger website, but specific trial duration and terms are not disclosed on the product pages.
