Moon KMP Libraries

A collection of Kotlin Multiplatform libraries for building cross-platform mobile apps.

Architecture

These libraries provide dependency-free interfaces. No Firebase, Google Play, or Apple SDK dependencies in the OSS layer.

App (composeApp)
 └── App Library (splitly-auth, splitly-billing, ...)    ← Platform SDKs here
      └── OSS Library (moon-auth-kmp, moon-billing-kmp, ...) ← Pure Kotlin interfaces

Each module ships with NoOp implementations for testing and unsupported platforms.

Quick Start

Local Development (includeBuild)
