-## 0. what is go-zero
 
 go-zero (listed in CNCF Landscape: [https://landscape.cncf.io/?selected=go-zero](https://landscape.cncf.io/?selected=go-zero)) is a web and rpc framework with lots of builtin engineering practices. It’s born to ensure the stability of the busy services with resilience design and has been serving sites with tens of millions of users for years.
 
 go-zero contains simple API description syntax and code generation tool called `goctl`. You can generate Go, iOS, Android, Kotlin, Dart, TypeScript, JavaScript from .api files with `goctl`.
