Swagger

Swagger is a comprehensive suite of tools for designing, documenting, and consuming RESTful APIs based on the OpenAPI Specification. It provides an end‑to‑end workflow that helps teams define API contracts, generate interactive documentation, and integrate those definitions into development and testing processes.

Core capabilities include visual API design, automatic generation of OpenAPI definitions, and interactive documentation through Swagger UI, which allows users to explore endpoints, view request and response schemas, and execute calls directly from the browser. Swagger Editor supports authoring and validating OpenAPI definitions in YAML or JSON, ensuring consistency and correctness before implementation. With Swagger Codegen and related generators, developers can create server stubs and client SDKs in multiple programming languages, reducing manual boilerplate and improving alignment between teams.
