The short version

  • Each has a real cost: Corteza planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.; 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: Corteza covers Corteza Low Code, Swagger/OpenAPI covers OpenAPI Specification.

Where each one falls short

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

Corteza

  • Planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.
  • No pricing is published for Planet Crusts support, hosting or implementation services, so the true running cost of a supported deployment cannot be estimated without a sales conversation.
  • The connector ecosystem is small compared with commercial low-code platforms, so integrations with common SaaS tools usually mean writing against the REST API rather than installing something.
  • Hiring is hard: almost nobody has Corteza on a CV, so you are training internal developers on a niche platform and you cannot easily replace them.
  • The bundled CRM is a starting point rather than a mature product, and teams that expect Salesforce-equivalent sales functionality out of the box will spend months building the gap themselves.

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

Corteza: Is Corteza the same thing as Crust?

Yes. The project was branded Crust and renamed Corteza in 2019 when Crust Technology donated it to the Commons Conservancy.

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.

Corteza: Who owns the code?

The Commons Conservancy, a Dutch foundation. Planet Crust in Cork is the primary developer and sells commercial services around it.

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
Corteza: Is there a paid enterprise edition?

No. Corteza is Apache 2.0 with no feature gating. Planet Crust sells support, hosting and development instead of a restricted edition.

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
Corteza: Can it genuinely replace Salesforce?

For case management and a straightforward sales pipeline on a self-hosted footprint, yes. For a large sales organisation relying on AppExchange products and a mature ecosystem, no.

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.
