KOtlin DEpendency INjection

KODEIN is a straightforward and yet very useful dependency retrieval container. it is effortless to use and configure.

KODEIN works on all Kotlin Multiplatform targets:

  • JVM / Android.
  • all Native platforms (iOS, macOS, Linux, Windows, WebAssembly).
  • Javascript / WasmJs.

KODEIN allows you to:

  • Lazily instantiate your dependencies when needed
  • Stop caring about dependency initialization order
  • Bind classes or interfaces to their instance or provider
  • Debug your dependency bindings and recursions

KODEIN provides extensions to be integrable into:

An example is always better than a thousand words:

val di = DI {
    bindProvider<Dice> { RandomDice(0, 5) }
    bindSingleton<DataSource> {"path/to/file") }

class Controller(private di: DI) {
    private val ds: DataSource by di.instance()

KODEIN is a good choice because:

  • It proposes a very simple and readable declarative DSL
  • It is not subject to type erasure (as Java is)
  • It integrates nicely with Android
  • It proposes a very kotlin-esque idiomatic API
  • It is fast and optimized (makes extensive use of inline)


Kodein is available on Maven Central.

repositories {
kotlin {
    sourceSets {
        commonMain {
            dependencies {

KODEIN 7+ is the current major version, but documentation is available for previous versions.
