The short version

  • Only Swagger/OpenAPI has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Tink visa owns Tink, and pay-by-bank exists to move payments off card rails, so the roadmap and pricing of the product you are using to reduce interchange are set by the company that earns the interchange.
  • They diverge on capability: Swagger/OpenAPI covers OpenAPI Specification, Tink covers Account data access.
  • 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.

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

Tink

  • Visa owns Tink, and pay-by-bank exists to move payments off card rails, so the roadmap and pricing of the product you are using to reduce interchange are set by the company that earns the interchange.
  • Coverage is Europe only, so a product serving both European and United States users runs a second aggregator with a different data model and a separate contract.
  • PSD2 connection quality varies sharply by bank, and headline connection counts hide wide differences in success rate, consent lifetime and re-authentication frequency that determine what users actually experience.
  • Consent under PSD2 expires and requires periodic re-authentication, so any product depending on continuous data access has a recurring user friction it cannot design away, and drop-off at re-consent is a real product problem.
  • Pricing is quoted with data access and payment initiation priced separately, and there is no published rate card, so small merchants cannot compare pay-by-bank economics against card acceptance without a sales process.

Answered from the vendors’ own pages

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
Tink: Who owns Tink?

Visa, since 2022. That is directly relevant if you are adopting pay-by-bank specifically to reduce card costs.

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
Tink: Do I need my own PSD2 licence?

No. Tink holds AIS and PIS licences from the Swedish FSA passported across the EEA, and customers can operate as its agent rather than obtaining their own authorisation.

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
Tink: Does Tink cover the United States?

No. It is a European platform. US coverage requires a separate provider.

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.

Source
Tink: How reliable are the bank connections?

It varies by institution far more than the headline count of roughly 6,000 connections suggests. Ask for per market and per bank success rates and consent lifetimes for the banks your users actually hold accounts with.
