Compose Multiplatform

A declarative UI framework by JetBrains for sharing high-performance Kotlin codebases across Android, iOS, desktop, and web.

Compose Multiplatform extends Google’s Jetpack Compose to provide a unified development experience across mobile, desktop, and web targets. By leveraging the Skia graphics engine (Skiko) for hardware-accelerated rendering, it ensures consistent UI behavior on iOS and desktop while maintaining 100% compatibility with native Android artifacts. Developers can share up to 90% of their codebase (including state management and Material 3 components) while retaining the flexibility to drop into platform-specific APIs like ARKit or Core Data using Kotlin Multiplatform’s expect/actual mechanism. It is the professional choice for teams looking to bypass the overhead of Flutter or React Native without sacrificing native performance.
