Swagger is an open-source framework by SmartBear for designing, building, documenting, and consuming RESTful APIs using the OpenAPI Specification. Originally created by Wordnik in 2011, Swagger became the OpenAPI Specification (OAS) in 2016 under the OpenAPI Initiative. The Swagger toolset includes Swagger UI for interactive documentation, Swagger Editor for writing OpenAPI specs, and Swagger Codegen for generating client SDKs and server stubs. The latest OpenAPI standard version is 3.2.0 (released September 2025).
