# openapi-generator

> Generate API clients, server stubs, and docs from OpenAPI specs

OpenAPI Generator creates API client libraries, server stubs, documentation, and configuration from OpenAPI 2.0 and 3.x specifications across dozens of programming languages. It helps developers adopt contract-first workflows and automate SDK maintenance in CI/CD pipelines. It runs as a CLI tool, Maven or Gradle plugin, Docker container, or self-hosted HTTP service.
