About

NSwag is a comprehensive Swagger/OpenAPI 2.0 and 3.0 toolchain for .NET, .NET Core, ASP.NET Core, and TypeScript, written in C#. It enables developers to generate OpenAPI specifications from existing API controllers and create client code from these specifications. NSwag combines functionalities similar to Swashbuckle (for OpenAPI/Swagger generation) and AutoRest (for client generation) into a single toolchain, eliminating the need for both. Key features include the ability to generate Swagger 2.0 and OpenAPI 3.0 specifications from C# ASP.NET (Core) controllers, serve these specifications via ASP.NET (Core) middleware with integrated Swagger UI or ReDoc, and generate C# or TypeScript clients/proxies from the specifications. NSwag offers multiple usage methods, including a user-friendly Windows GUI (NSwagStudio), command-line interfaces compatible with Windows, Mac, and Linux, and integration into C# code via NuGet packages.

About

Octri is a hosted platform for teams that publish APIs. It turns API specifications into reference documentation, client SDKs, an MCP server, and production monitoring. Teams can import an OpenAPI spec from a file, URL, or GitHub repository, review and edit generated endpoint documentation, add written guides, and publish docs on a custom domain. SDK Studio configures clients in ten languages and can publish packages to language registries. The MCP server exposes documentation and selected API endpoints as tools for compatible AI clients. Optional monitoring reports errors from generated SDKs so API teams can investigate client-side failures. A command-line tool supports specification, SDK, documentation, and monitoring workflows. A free plan is available with usage limits; paid plans add capacity and features.
