Swagger was an open-source framework originally developed by Tony Tam at Wordnik to design, build, document, and test RESTful APIs. It provided a standardized way to describe API endpoints, methods, request parameters, and response formats using a machine-readable JSON or YAML format. Swagger allowed developers to generate interactive documentation, enabling users to test API calls directly within a web interface. It also supported code generation for client SDKs and server stubs, streamlining API development and integration. Swagger later evolved into the OpenAPI Specification (OAS) and is now maintained by the OpenAPI Initiative, continuing to be a foundational tool for modern API-first development practices.
