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 Swagger Codegen can simplify your build process by generating server stubs and client SDKs for any API, defined with the OpenAPI (formerly known as Swagger) specification, so your team can focus better on your API’s implementation and adoption. Moving from design to development has never been easier with Swagger Codegen in SwaggerHub. API Definition files can be used to create stubs in popular languages, like Java, Scala, and Ruby, with just a few clicks.
