  • Pricing for the desktop and web products is not published, while the terminal client is free and open source
  • The graphical versions are newer than the CLI, so parity between them is not guaranteed

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
