## What it is
Kodein is a painless Kotlin dependency injection container with a simple declarative DSL. It supports all Kotlin Multiplatform targets and integrates with Android, Compose, and Ktor.

## Use cases
- manage dependencies in a Kotlin multiplatform app
- inject dependencies into Android activities and fragments
- use dependency injection with Ktor server
- lazily instantiate services in a Kotlin project
- replace Dagger or Koin with a simpler DI container
- bind interfaces to implementations in Kotlin

## When to choose
- you want a simple, idiomatic Kotlin DI DSL
- you need DI across JVM, Android, iOS, JS, and Native targets
- you use Compose or Ktor and want first-class integration

## When to avoid
- you need compile-time DI verification like Dagger
- your project is Java-only without Kotlin
- you need a very large-scale enterprise DI framework with advanced scoping

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, plugin-system
- domain: developer-tools, mobile-development, cross-platform, web-development
- platform: jvm, windows, wasm
- tags: dependency-injection, kotlin-multiplatform, di-container, ktor, compose, android, ios, macos, linux
