The World Standard for RESTful APIs
The OpenAPI Specification was donated to the Linux Foundation under the OpenAPI Initiative in 2015. The specification creates a RESTful interface for easily developing and consuming an API by effectively mapping all the resources and operations associated with it.

The Swagger tools were developed by the team behind the original "Swagger" Specification. Swagger offers the most powerful and easiest to use tools to take full advantage of the OpenAPI Specification.
Streamline your API’s build process by keeping its design, documentation, and implementation synchronized and updated automatically
Develop APIs in the technology stack of your choice with client libraries and server templates in every popular language
The OpenAPI Specification is a community-driven open specification within the Open API Initiative, a Linux Foundation Collaborative Project.
The OpenAPI Specification can be implemented across the API lifecycle.
OAS offers the complete format for designing APIs, defining resources and operations before writing code a line of code.
Visualize your APIs operations and let internal developers and external consumers quickly adopt your API.
Generate scaffolding for server stubs and client SDKs, based on your OAS definition
Automate test case generation by defining a successful response in your OAS definition.
Use the operations defined in your OAS generation to create API monitors.
Supported by leading API gateways like AWS, IBM, Apigee, and more.
The Swagger tools support advanced Swagger users, and teams that are just beginning their journey with the OpenAPI Specification.
