## What it is
AutoRest is an OpenAPI (Swagger) specification code generator that produces client libraries for RESTful web services in languages like C#, Go, Java, Python, TypeScript, and PowerShell. It is deprecated and will be retired on July 1, 2026, with TypeSpec recommended as its successor.

## Use cases
- generate a typed REST client from an OpenAPI spec
- generate SDK client libraries for Azure APIs
- convert swagger yaml into C# or Python client code
- generate PowerShell cmdlets from an OpenAPI description
- scaffold API clients in multiple languages from one spec

## When to choose
- maintaining legacy projects already built on AutoRest
- generating clients from existing OpenAPI 2.0/3.0 specs before migrating to TypeSpec

## When to avoid
- starting a new project - use TypeSpec instead
- needing new language generators or features
- long-term support beyond July 2026

## Facets
- artifact type: cli-tool
