AutoRest

aid: autorest
name: AutoRest
description: 'AutoRest is an open source tool from Microsoft (MIT License) that generates client libraries for accessing RESTful
  APIs from OpenAPI specifications. It powers generation of Azure SDKs across C#, Python, Java, TypeScript, Go, PowerShell,
  and Swift with an extensible plugin architecture. Note: AutoRest is deprecated as of 2026 with retirement on July 1, 2026.
  The recommended successor is TypeSpec, a modern API description language and code generation platform from Microsoft.'
