oapi-codegen is a command-line tool and Go library that generates Go server boilerplate, API clients, and HTTP models from OpenAPI 3.0/3.1 specifications. It reduces boilerplate so developers can focus on business logic while keeping generated code idiomatic and simple.
Use cases
- generate go server stubs from an openapi 3 spec
- create a typed go rest api client from swagger
- generate go models from openapi yaml
- spec-first api development in go
- split large openapi specs into multiple go packages
- validate openapi spec types against go type system
When to choose
- you build Go services or clients against an OpenAPI 3.0/3.1 spec and want spec-first codegen
- you want idiomatic, readable generated Go code rather than heavily abstracted output
- you need server boilerplate for popular Go routers or a typed HTTP client
When to avoid
- your API is defined in Swagger 2.0 rather than OpenAPI 3.x
- you work outside the Go ecosystem
- you prefer runtime schema validation over generated code
