## What it is
A Go implementation of the Swagger 2.0 (OpenAPI 2.0) specification with a CLI tool for working with swagger specs. It generates servers, clients, and models from specifications, and can generate specs from annotated Go code.

## Use cases
- generate a go server from a swagger spec
- generate a go api client from openapi 2.0
- generate swagger spec from annotated go code
- validate and work with swagger 2.0 documents
- scaffold rest api server and models from openapi

## When to choose
- you use OpenAPI/Swagger 2.0 and want idiomatic Go server or client code
- you want to generate a spec from Go source annotations
- you need a mature, actively maintained swagger toolchain for Go

## When to avoid
- you need OpenAPI 3.x support
- you prefer writing handlers by hand without code generation
- you use a different language ecosystem

## Facets
- artifact type: cli-tool
- maturity: active
- function: api-framework, serialization, http-server, http-client
- domain: apis, developer-tools, web-development, backend
- platform: go, cli, cross-platform
- tags: swagger, openapi-2-0, codegen, rest-api, specification, server-generation, client-generation, code-generation, docker
