As the name suggests, the OpenAPI Specification (OAS) is driven by an open source community that's focused on the OpenAPI Initiative within the Linux Foundation Collaborative Project.
In a few words, the OpenAPI Specification is a language-agnostic interface that was designed for REST APIs and allows consumers to discover the capabilities of a service without even knowing what code base is being used to implement the API. The API may not even be ready to use or have a single line of code written. The main reason for this is mentioned in the documentation provided by OpenAPI. Once you have an OpenAPI Specification for your API, it is easy to add the Swagger UI to the project as an interactive communication tool.
Swagger is a project that's composed of tools that help the developers of REST APIs in tasks such as the following:
