go-swagger is a toolkit for working with Swagger/OpenAPI 2.0 specifications in Go. It generates server, client, and CLI code from a specification document, and can also produce a specification by scanning annotated Go source code. The project includes a static validation engine that checks documents against the schema and project-specific rules, and a specification transformation pipeline that resolves, flattens, and merges documents. The toolkit generates both client and server code from the same specification, ensuring consistency in request and response handling. It also produces a command

NSwag is an OpenAPI toolchain for .NET that provides a suite of generators for converting OpenAPI specifications and JSON schemas into clients, server stubs, and structured documentation. It enables the creation of type-safe client libraries and data transfer objects, as well as the generation of OpenAPI specifications by analyzing .NET controllers. The project supports contract-first API development by generating server controller stubs from specifications and offers dedicated TypeScript API integration to ensure type safety in frontend applications. It also provides tools for hosting intera

FastStream is an asynchronous Python framework designed for building event-driven microservices. It provides a unified abstraction layer for interacting with various message brokers, enabling developers to manage event production and consumption through a consistent interface while maintaining access to native provider-specific features. The framework centers on a decorator-based routing model that binds application logic directly to broker topics, supported by a built-in dependency injection container that resolves resources at runtime. The framework distinguishes itself through its deep int

FastStream is an asyncio message broker framework for building event-driven applications in Python. It provides a unified interface and a multi-broker messaging abstraction layer that translates generic producer and consumer calls into broker-specific APIs. The framework features a built-in dependency injection container and uses decorators to route messages to asynchronous handler functions. It includes a documentation generator that extracts channel definitions and message formats from code to produce standardized AsyncAPI specifications. The project supports integration with Kafka, Rabbit

Connexion 是一个规范驱动的框架，用于构建自动将 OpenAPI 规范映射到应用逻辑的 API。它使用这些规范来自动化路由、请求验证和响应序列化，并通过操作 ID 将 API 操作链接到后端处理函数。 该项目通过提供一个模式驱动的 Mock 服务器来区分开来，该服务器使用规范中的示例响应来模拟 API 行为，而无需后端逻辑。它还包括一个动态文档托管系统，将 API 规范转换为实时交互式控制台，用于探索和测试端点。 该框架涵盖了广泛的功能领域，包括通过基于中间件的身份验证和作用域验证实施安全性、可插拔的请求和响应验证逻辑，以及向类型化函数参数自动注入参数。它还提供了用于应用生命周期管理、自定义中间件集成和请求模拟测试的实用工具。 该项目可用于引导独立 Web 应用，或包装在现有框架周围以添加规范驱动的功能。

gin-swagger 是 Gin Web 框架的 Swagger UI 中间件，作为 OpenAPI 2.0 文档生成器。它提供了一个交互式 REST API 沙盒和一个用于可视化 API 契约及测试端点的基于浏览器的界面。 该项目允许通过为每个定义分配唯一名称，在单个路由器上托管多个 API 定义。它支持自定义界面的视觉呈现和行为，包括控制展开深度和授权持久化。 该中间件拦截路由以 JSON 载荷形式交付 API 定义，并将 UI 所需的静态资产直接嵌入二进制文件中。它促进了交互式 API 测试，以通过 Web 浏览器验证请求和响应结构。

Flasgger is a documentation framework for Flask applications that generates OpenAPI specifications and an integrated Swagger UI. It functions as a documentation generator and specification parser that extracts API schemas from route definitions, function docstrings, and external specification files. The tool allows API definitions to be maintained either within the source code using YAML blocks in docstrings or decoupled into standalone YAML files. It provides a browser-based interactive console for testing and exploring API endpoints directly from the web application. Beyond documentation,

springdoc-openapi is a library and toolset that analyzes Spring applications at runtime to produce machine-readable OpenAPI specifications in JSON and YAML formats. It serves as an integrator that extracts API metadata from Java source code and annotations to automate documentation for Spring-based services. The project distinguishes itself through its ability to aggregate API specifications from multiple remote microservices into a single unified interface and provide multiple visualization options, including Swagger UI and Scalar. It also offers a dedicated plugin for exporting documentatio
