The short version

  • Only Swagger UI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Delinea the Thycotic and Centrify lineages are integrated unevenly, so buying the full portfolio means running consoles and agents that do not share one administrative model as cleanly as the marketing suggests.; Swagger UI only as good as the specification: a thin OpenAPI file produces thin documentation
  • They diverge on capability: Delinea covers Secret Server, 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.

Delinea

  • The Thycotic and Centrify lineages are integrated unevenly, so buying the full portfolio means running consoles and agents that do not share one administrative model as cleanly as the marketing suggests.
  • Modules are licensed separately by different units, per privileged user for the vault and per endpoint for privilege management, which makes total cost hard to model and easy to underestimate at scale.
  • Delinea does not publish rates, so buyers benchmark against third party and public sector listings; expect list prices to be negotiable by a wide margin, which means the first quote is not the price.
  • Thoma Bravo ownership since 2021 has coincided with firmer renewal pricing, and buyers with a single-vendor PAM estate have little leverage once credentials are inside the vault.
  • Migrating out of a privileged access vault is a genuinely hard project because every automated process that fetches a secret has to be repointed, so the switching cost is real and the vendor knows it.

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

Delinea: Is Delinea the same as Thycotic?

Delinea is the merged company formed from Thycotic and Centrify in 2021. Secret Server is the former Thycotic product; the server access products come from Centrify.

Swagger UI: Is Swagger UI free?

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

Delinea: Is pricing published?

Not by Delinea. Public sector frameworks have listed Secret Server Cloud around 348 GBP per user per year, which is a reference point, not a quote.

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.

Delinea: Does one licence cover endpoints and servers?

No. Secret Server, Privilege Manager and Server PAM are separately licensed on different units. Scope all three if your requirement spans them.

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.
