About SwaggerHub
SwaggerHub is the hosted platform from SmartBear built around the OpenAPI standard that Swagger made popular. Teams use it to design APIs together, keep definitions in version control and publish clear documentation.
It checks designs against shared standards, generates server and client code from the spec, and ties into testing tools so the contract and the implementation stay in sync. Newer AI features help draft and improve definitions.
There are free and paid tiers, with enterprise options for larger companies. It is a natural fit for teams already working with Swagger and OpenAPI.
