The short version

  • Only Swagger UI has a free tier, so it costs nothing to try first.
  • Each has a real cost: IDnow agent-led video identification costs several times an automated check and depends on agent availability, so peak-time queues push abandonment up at exactly the moment conversion matters.; Swagger UI only as good as the specification: a thin OpenAPI file produces thin documentation
  • They diverge on capability: IDnow covers VideoIdent, Swagger UI covers OpenAPI rendering.
  • 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.

IDnow

  • Agent-led video identification costs several times an automated check and depends on agent availability, so peak-time queues push abandonment up at exactly the moment conversion matters.
  • Pricing is quoted with an annual volume commitment, so the accreditation advantage comes with a floor you pay whether or not you use it.
  • The product is optimised for European regulatory regimes, so buyers verifying users in North America, Asia or Africa will find coverage and cost less competitive than global specialists.
  • Qualified electronic signature is a separate licence from identity verification, which surprises buyers who assumed the accredited identity check made the signature capability included.
  • Integration for the regulated flows is heavier than a simple SDK drop-in because the compliant journey, including consent and recording requirements, constrains the user experience you can build.

Swagger UI

  • Only as good as the specification: a thin OpenAPI file produces thin documentation
  • Default presentation is dated compared with modern documentation tools
  • Large specifications render slowly and become hard to navigate
  • Try it out against production needs care with authentication and CORS, and is often disabled as a result

Answered from the vendors’ own pages

IDnow: Why choose it over a cheaper automated vendor?

Because in some European regimes the cheaper vendor is not legally permitted for the transaction. This is an eligibility question, not a quality one.

Swagger UI: Is Swagger UI free?

Yes, open source under the Apache 2.0 licence. SmartBear sells commercial SwaggerHub separately.

IDnow: Is the electronic signature included?

No. Qualified electronic signature under eIDAS is licensed separately from identity verification.

Swagger UI: What is the difference between Swagger and OpenAPI?

OpenAPI is the specification format; Swagger is the toolset around it, including Swagger UI. The specification was renamed from Swagger to OpenAPI in 2016.

IDnow: Where is the data processed?

In European data centres, which is a requirement rather than a preference for many of its regulated customers.

Swagger UI: Can Swagger UI make real API calls?

Yes, through its try-it-out control, though authentication and CORS configuration often mean it is disabled for production APIs.
