Calf is a Kotlin library for Compose Multiplatform that provides adaptive UI components and wrappers for platform-specific APIs such as file picker, WebView, and permissions. It lets a single codebase render native look-and-feel UI across Android, iOS, Desktop, and Web.

Use cases

build adaptive UIs with Compose Multiplatform
pick files natively from Android, iOS, and desktop in shared Kotlin code
embed a WebView in a Compose Multiplatform app
request and handle runtime permissions in Kotlin Multiplatform
use Cupertino-style icons cross-platform

When to choose

you're building a Compose Multiplatform app and need native platform APIs like file picker or permissions
you want UI components that adapt to each platform's look and feel
you need a shared-code WebView across Android, iOS, and desktop

When to avoid

your app is single-platform native (plain Android or iOS) where platform SDKs suffice
you need geolocation, maps, notifications, or media players - those modules are still marked coming soon
you don't use Kotlin or Compose Multiplatform
