| Sponsored// Speakeasy Generate & publish SDKs in 10+ languages, Terraform Providers, and docs from your OpenAPI | v3.1, v3 | |
| ABAP OpenAPI Client & Server Generator ABAP OpenAPI Client & Server Generator written in ABAP. Code generation runs also in the Browser and on command line using NodeJS. | v3 | |
| api-codegen-ts Generates TypeScript models, response validators, and operation controllers from OpenAPI descriptions | v3, v2 | |
| APIMatic CodeGen Bring in your API description (OAI v2/v3, RAML, API Blueprint, WSDL, etc.) to generate fully functional SDKs in over 10 languages. | v3.1, v3, v2 | |
| Azure AutoRest Generates client libraries for accessing RESTful web services from an OpenAPI document. Supports C#, PowerShell, Go, Java, Node.js, TypeScript, Python, and Ruby. | v3, v2 | |

| Counterfact Counterfact is a revolutionary free and open source mock server. If you have Node installed, all you have to do is run `npx counterfact@latest path-or-url-to-your-openapi-document`. Out of the box, you'll get a mock server that returns random data. With a TypeScript API that's optimized for mocking, you can add more realistic behavior. It supports mix and matching mocks with calls to the real API (sans CORS headaches). With hot reloading and a REPL, you can change things up on the fly. | v3.1, v3, v2 | |
| docler-labs/api-client-generator API client generator is a console application capable of auto-generating a PSR18/PSR7 API client based on OpenAPI specification according to PHP best practices and your code style standards. | v3 | |
| docs A modern alternative to `go-swagger`. Offers generation and parsing of OpenAPI Specs, depending on the usage. | v3.1, v3 | |
| draig DRAIG is an OpenAPI3 based design-first custom generator that creates fully functional microservices from an OAS API description document. You can use DRAIG with openapi-generator as a backend generator or use DRAIG CLI or REPL to generate your microservices. With simple user-customizable templates, you can extended and improve implementation code so that generated code can be compiled and deployed immediatelly. | v3 | |
| FabriKt A sophisticated Kotlin code generation library capable of generating Jackson-annotated data classes, Spring Controller interfaces, and fault-tolerant OkHttp clients. Written in Kotlin, this library programatically generates code and is capable of handling advanced OpenApi3 specification features such as polymorphism. | v3 | |
| Flotiq - headless CMS with OpenAPI support Visually define your Content Types, Flotiq automatically generates your own OpenAPI v3 compatible endpoints, SDKs and Postman collections. | v3 | |
| go-swagger Unmaintained v2.0 only project seeking new maintainer, or probably a fork. Parser, validator, generates descriptions from code, or code from descriptions! | v2 | |
| guardrail Principled code generation from OpenAPI descriptions | v3, v2 | |
| janephp/open-api Generate a PHP Client API (PSR-7 compatible) given a OpenAPI specification. | v3, v2 | |
