Compose Multiplatform is a declarative framework for sharing UI code across multiple platforms with Kotlin.It is based onJetpack Compose and developed byJetBrains and open-source contributors.

You can choose the platforms across which to share your UI code using Compose Multiplatform:

• iOS
• Android
• Desktop (Windows, MacOS, and Linux)
• Web (Beta)

For example, you can share UIs between iOS and Android or Windows and MacOS.

Compose Multiplatform shares most of its API with Jetpack Compose, the Android UI framework developed by Google.You can use the same APIs to build user interfaces for both Android and iOS.

Since Compose is built on top ofKotlin Multiplatform,you can easily access native APIs, such as theCamera API,and embed complex native UI views, such asMKMapView.

When Android is one of your targets, you get the same experience for Android as if you were developing an Android appusingJetpack Compose.

Web support is in Beta, making it a great time to give it a try. Check out ourblog post to learn more about the progress made to reach this milestone.We would appreciate your feedback on it in the public Slack channel#compose-web.If you face any issues, please report them onYouTrack.

You can experiment with sharing your mobile or desktop UIs with the web. Compose Multiplatform for web is based onKotlin/Wasm,the newest target for Kotlin Multiplatform projects. It allows Kotlin developers to run their code in the browser withall the benefits that WebAssembly has to offer, such as good and predictable performance for your applications.
