What is this?
A declarative UI framework from JetBrains, built on top of Jetpack Compose, for sharing one UI codebase across platforms in Kotlin.
A declarative UI framework from JetBrains, built on top of Jetpack Compose, for sharing one UI codebase across platforms in Kotlin.So is it basically Jetpack Compose that also runs off Android?Essentially yes: it shares most of its API with Jetpack Compose, Google's Android UI framework, so you write the same Compose code for Android and iOS instead of learning a separate UI system per platform.

Since the APIs are shared, existing Compose knowledge transfers directly to the other targets.

Web feedback is collected via the #compose-web Slack channel and issues go to YouTrack.

Web is the only target still marked Beta.
iOS, Android, desktop (Windows, macOS, and Linux) and web. Web is the only target still marked Beta.What does the desktop target give me beyond the mobile UI model?It runs on the JVM with high-performance hardware-accelerated rendering on macOS, Windows and Linux, and adds desktop-only extensions for menus, keyboard shortcuts, window manipulation and notification management.

Compose sits on top of Kotlin Multiplatform, so you can access native APIs such as the Camera API and embed complex native UI views like MKMapView in your shared UI.

Unlike Compose Multiplatform it is not multiplatform — it works only with Kotlin/JS.
