The short version

  • Only Swagger UI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Swagger UI only as good as the specification: a thin OpenAPI file produces thin documentation; TrustArc the software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • They diverge on capability: Swagger UI covers OpenAPI rendering, TrustArc covers Nymity Research.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Swagger UI

  • Publishing API documentation that stays in step with the specificationnot TrustArc
  • Letting developers try endpoints before writing any client codenot TrustArc
  • Internal API discovery across teamsnot TrustArc

TrustArc

  • A consumer brand that needs an independent privacy seal on its website because enterprise customers or app stores ask for third-party verificationnot Swagger UI
  • A multinational privacy team that needs a maintained answer to what a given jurisdiction requires without retaining outside counsel for every questionnot Swagger UI
  • An organisation running DPIAs at volume that wants templates tied to a maintained regulatory library rather than to a consultant word documentnot Swagger UI
  • A privacy programme being audited that needs documented maturity benchmarking against a recognised framework of programme activitiesnot Swagger UI

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

TrustArc

  • The software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • The integration catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.
  • Certification services are sold separately from the platform subscription, so the seal that is often the reason for choosing TrustArc is an extra line item and an extra annual renewal.
  • Reported contract values vary enormously by module mix and organisation size, and the absence of published pricing means smaller buyers have no anchor and routinely discover the entry price is higher than expected.
  • TrustArc stays inside privacy, so organisations that later want third-party risk, security compliance or ethics reporting on the same platform will be running a second vendor anyway.

Answered from the vendors’ own pages

Swagger UI: Is Swagger UI free?

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

TrustArc: What does TrustArc have that OneTrust does not?

Nymity Research, a maintained regulatory intelligence library acquired in 2019, and the TRUSTe third-party certification and seal programme.

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.

TrustArc: How much does TrustArc cost?

Not published. Reported enterprise agreements range widely depending on modules and organisation size, and certification services are quoted on top of the platform subscription.

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.

TrustArc: Is TRUSTe the same company?

Yes. TrustArc is the renamed TRUSTe business and still operates the TRUSTe certification programme as a subsidiary.

TrustArc: Does it handle cookie consent for Europe?

Yes, it includes a consent manager with scanning and banner delivery, though pure-play consent vendors are cheaper if that is all you need.
