TypeHub is a next generation API and data design platform.
SwaggerHub is a platform for designing, building, documenting, and consuming RESTful APIs. It is developed by SmartBear Software. SwaggerHub provides a collaborative environment for teams working on API development, allowing them to streamline the entire API lifecycle.
TypeHub challenges SwaggerHub as a solution to design API specifications. The strength of TypeAPI is the advanced SDK code generator which produces ready to use and clean code. Another advantage is the Git like behaviour, this means that every change to your specification is saved as commit and you can also create pull requests to an existing specification. TypeHub works internally with the TypeAPI specification instead of OpenAPI which is specifically designed for code generation. But it is also easily possible to import an existing OpenAPI specification into TypeHub.
