## What it is
Compose Multiplatform is a declarative UI framework by JetBrains, based on Jetpack Compose, for sharing UI code across Android, iOS, desktop (Windows/macOS/Linux), and web (beta) using Kotlin. It provides native-quality rendering, native API interop, and desktop extensions like menus, window management, and hot reload.

## Use cases
- share one UI codebase between iOS and Android apps
- build a desktop app in Kotlin with hardware-accelerated rendering
- reuse Jetpack Compose skills to target iOS and web
- build a cross-platform app with 90%+ shared code
- prototype UI changes quickly with hot reload
- embed native views like MKMapView in a shared UI

## When to choose
- your team already knows Jetpack Compose or Kotlin
- you want a single declarative UI codebase across mobile, desktop, and web
- you need native performance and access to platform APIs
- you're building a production Android/iOS or desktop app

## When to avoid
- you need a fully mature web target (still beta)
- your team is committed to Swift/SwiftUI or Flutter ecosystems
- you require deep platform-specific UI that outweighs sharing benefits
- you need a pure native look with platform-standard widgets on every platform
