Swashbuckle.AspNetCore is a library that generates OpenAPI (Swagger) documents for ASP.NET Core APIs directly from code, with an embedded Swagger UI for exploring and testing endpoints. It supports Swagger 2.0 and OpenAPI 3.0/3.1, keeping API documentation automatically in sync with the latest code.

Use cases

• generate openapi documentation for asp.net core api
• add swagger ui to web api
• document rest api endpoints automatically
• test api endpoints from a browser ui
• produce openapi json for client code generation
• keep api docs in sync with code

When to choose

• you build ASP.NET Core APIs and want living, code-generated OpenAPI docs
• you want an embedded Swagger UI with minimal setup
• you need OpenAPI 2.0/3.0/3.1 output for downstream tooling like client generators

When to avoid

• your API is not built on ASP.NET Core / .NET
• you need hand-authored, heavily customized documentation rather than code-generated specs
• you use a non-Microsoft web framework with its own OpenAPI tooling
