FastAPI is a web framework for building APIs with Python. It leverages standard language type hints to provide automatic data validation, request parsing, and interactive API documentation generation. The framework supports asynchronous request handling and manages execution contexts to prevent blocking the main event loop. The project includes a dependency injection system that allows for the resolution and injection of reusable components into request handlers. This system supports request-scoped caching, lifecycle management, and integration with security mechanisms like OAuth2 and JSON We

This project is a REST-to-gRPC API gateway and JSON reverse proxy that translates RESTful HTTP requests into gRPC service calls. It functions as a protocol buffer proxy generator, providing the tools necessary to bridge JSON-based HTTP traffic with backend gRPC servers. The system distinguishes itself by automating the creation of reverse-proxy servers and stubs through protobuf-driven code generation. It also includes a dedicated OpenAPI specification generator that produces OpenAPI v2 and v3 documents from gRPC service definitions and annotations. The project covers a broad range of integr

swagger-core is a set of libraries for parsing, generating, and serializing OpenAPI specifications to automate REST API documentation. It provides tools to read, validate, and transform JSON or YAML specifications into programmable objects, as well as a generator that scans source code and annotations to create formal technical descriptions of an API. The project enables bi-directional specification serialization, allowing in-memory API definitions to be converted between native language objects and structured files. It uses a plugin-based scanning mechanism and annotation-driven generation t

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

TypeSpec is a language for defining cloud API shapes and generating OpenAPI, JSON Schema, and client/server code from a single source of truth. It functions as a protocol-agnostic API designer that models REST, gRPC, and other API protocols using a unified, extensible syntax, with a decorator-based metadata system for attaching metadata, validation rules, and lifecycle visibility to API models and operations. The compiler produces OpenAPI 3.0 specifications and other artifacts, and the tool supports declaring API versions and tracking changes to models, properties, and operations across releas

Huma is an OpenAPI REST framework for Go designed for building HTTP services with automatic OpenAPI 3.1 specification generation and JSON Schema validation. It serves as a toolkit for developing REST and RPC APIs with typed inputs and outputs, deriving interactive documentation directly from the source code. The framework distinguishes itself by automating the synchronization between implementation and documentation. It uses a content-negotiation engine to manage multiple serialization formats via client headers and employs a JSON Schema input validator to automatically verify request paramet
