Swagger used to consist of the specification and a large ecosystem of tools to implement the specification. These tools include everything from front-end user interfaces, low-level code libraries and commercial API management solutions. In 2015, SmartBear Software donated the Swagger specification to the Linux Foundation, and renamed the specification to the OpenAPI Specification. SmartBear also became the founding member of the OpenAPI Initiative (OAI), a body to govern the development of the OAS in an open and transparent manner.
