# AutoRest

**Canonical:** https://apis.io/providers/autorest/  
**APIs profiled:** 6

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.
