The short version

  • Only Swagger/OpenAPI has a free tier, so it costs nothing to try first.
  • Each has a real cost: 3scale red Hat's managed 3scale services end on 30 June 2027, so anyone adopting the hosted option now is choosing a product with a published end date; 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: 3scale covers API Gateway, Swagger/OpenAPI covers OpenAPI Specification.
  • Prices and features above were last checked on 30 August 2026.
