# What is KOIN? ✨
 
Koin is a pragmatic, lightweight dependency injection framework for Kotlin developers, developed by [Kotzilla](https://kotzilla.io) and open-source [contributors](https://github.com/InsertKoinIO/koin/graphs/contributors).

```
The pragmatic Kotlin & Kotlin Multiplatform Dependency Injection framework
- Simple, Powerful and now Compile-Safe -
```

## Compile-Safe Dependency Injection 🛡️

Koin is now **compile-safe** thanks to the [Koin Compiler Plugin](https://github.com/InsertKoinIO/koin-compiler-plugin). Your dependency graph is verified at compile time — missing bindings, broken definitions, and misconfigured modules are caught by the compiler instead of crashing at runtime.

- Catch missing or invalid dependencies before you run your app
- Keep Koin's concise, idiomatic DSL — no extra boilerplate
- Works across Kotlin & Kotlin Multiplatform targets

Get started with the [Koin Compiler Plugin](https://github.com/InsertKoinIO/koin-compiler-plugin).
