This project is a command-line tool and template-based scaffolding engine that transforms API interface specifications into functional client libraries and server stubs. By automating the creation of type-safe SDKs and boilerplate code, it bridges the gap between service definitions and implementation, allowing developers to maintain synchronized codebases across many programming languages. The tool distinguishes itself through a portable execution model that utilizes containerized build isolation to ensure identical output regardless of the host environment. It features a modular, plugin-bas
oapi-codegen is an OpenAPI specification compiler and code generator for Go. It transforms OpenAPI definitions into type-safe Go client libraries, server boilerplate, and data models to facilitate contract-first API development. The tool distinguishes itself through a flexible customization system that allows users to override generated types and imports via specification extensions. It supports the use of custom text templates to redefine the final source code structure and provides a specification overlay mechanism to modify or remove endpoints without altering the original source file. Th
OpenAPI Generator CLI is a command-line utility designed to automate the creation of API artifacts from specification files. It functions as a tool for generating client libraries, server stubs, and documentation, enabling developers to produce consistent boilerplate code and reference materials across various programming languages. The project provides a wrapper that manages the lifecycle of a Java-based execution engine, which performs the actual code synthesis using logic-less templates. To ensure reproducible results and avoid dependency conflicts on the host system, the tool supports ver
Fern is a toolset for managing API specifications, generating type-safe client libraries, and producing hosted developer documentation. It provides a utility for validating, transforming, and exporting API definitions into standardized OpenAPI formats, serving as a system to maintain a consistent source of truth for API designs. The project differentiates itself through an automated SDK distribution pipeline that publishes generated libraries to package managers such as npm, PyPI, Maven, and NuGet. It also includes an AI-powered search assistant trained on API and SDK specifications to answer
Swagger Codegen is a template-driven engine and multi-language toolkit used to generate API client SDKs, server stubs, and human-readable documentation from OpenAPI specifications. It translates these specifications into functional libraries and boilerplate routing code across various target programming languages.
The main features of swagger-api/swagger-codegen are: Client Library Generation, Client Library Generators, Server Stub Generation, API Code Generators, API Documentation Generators, Documentation Generators, Server Boilerplate Generators, Source Code Templates.
