Kotlin Multiplatform

Kotlin Multiplatform is an SDK that allows developers to share business logic across Android, iOS, web, and desktop while maintaining native performance.

Developed by JetBrains, Kotlin Multiplatform (KMP) enables teams to write core logic once and deploy it everywhere. Unlike traditional cross platform frameworks that abstract away the hardware, KMP integrates directly with native APIs (like Swift on iOS or Java on Android) to ensure zero performance overhead. Industry leaders like Netflix, McDonald's, and Forbes use it to reduce code duplication by up to 80% without sacrificing the look and feel of a native application. By pairing KMP with Compose Multiplatform, developers can also share UI components across platforms using a single declarative codebase.
