Kotlin Multiplatform (KMP) is a framework by JetBrains that allows developers to share code across multiple platforms—Android, iOS, desktop, web, and backend—while still writing platform-specific code where needed.
Key Features:
- Shared codebase: Business logic, networking, and data layers can be reused.
- Platform-specific APIs: Access native features on Android (Kotlin/JVM) and iOS (Kotlin/Native).
- Integration: Works with existing apps gradually (no need to rewrite everything).
- Efficiency: Saves development time and ensures consistency across platforms.
It’s especially popular for teams building cross-platform mobile apps while keeping native performance and UI.
