What is KOIN? ✨

Koin is a pragmatic, lightweight dependency injection framework for Kotlin developers, developed by Kotzilla and open-source 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. 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.
