Swashbuckle.AspNetCore is an API specification tool and documentation generator for ASP.NET Core. It extracts metadata from source code and models to produce standardized OpenAPI specifications and interactive browser interfaces for exploring and testing web APIs. The project integrates a middleware component to serve these specifications and a Swagger UI for interactive API testing directly from a running application. It also provides a command-line exporter to extract specification files from application assemblies for use in CI/CD pipelines. The tool covers a wide range of capabilities in
utoipa is a Rust API documentation tool used to generate machine-readable OpenAPI specifications. It functions as a specification generator and schema mapper that converts Rust structs and enums into compliant OpenAPI schemas. The project distinguishes itself by using procedural macros and traits to automate metadata extraction from code. It supports complex data modeling, including generics, polymorphism, and recursive type resolution, while synchronizing field renaming and tagging from serialization attributes. It also enables the composition of modular specifications, allowing multiple sma
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
swagger-php is an OpenAPI specification generator and PHP API documentation library. It scans PHP source code attributes and annotations to produce standardized specification files and interactive API references. The tool functions as a schema inference engine that derives data types and schemas from native PHP type hints and generic blocks. It uses reflection-based static analysis to extract metadata without executing application logic and supports recursive schema inheritance to merge definitions from parent classes and interfaces. The project includes a command-line utility for exporting
