Compose Multiplatform, by JetBrains

Compose Kotlin UI framework port for desktop platforms (macOS, Linux, Windows) and Web, components outside of the core Compose repository at https://android.googlesource.com/platform/frameworks/support.

Jetpack Compose for Android

Compose Multiplatform uses Jetpack Compose developed by Google when you target Android platform. See more info about it here.

The docs published by Google are great and decribe how to develop on Compose for Android.

Note that when you use Compose Multiplatform, you setup your project differently. You can create a multiplatform project with Android support via IDEA Project Wizard, or by copying multiplatform template. In androidMain source set you can use almost all information from the docs, and in commonMain source set you can use information from Foundation and Design sections.
