“After a successful initial test with the payments feature, we expanded Kotlin Multiplatform to our entire McDonald's application. With KMP, we saw fewer crashes and better performance across both platforms after the launch.
We transitioned from a separate Android and iOS team to a more unified mobile team.”

Netflix uses KMP to share logic for their mobile studio apps, reducing duplication and enabling faster, more reliable development. This approach helps deliver high-quality features efficiently in the fast-paced world of TV and movie production.
BiliBili (China version) has adopted Kotlin Multiplatform and Compose Multiplatform for the Instant Message feature.
“One exciting trend for Duolingo is that the more that we use Kotlin Multiplatform internally, the more we find ourselves speeding up in terms of shipping. It turns out after you learn something, you get really good at it. […] Now there's a lot more confidence behind it and we're building up that knowledge.”

Wrike adopted Compose Multiplatform early, with CMP-powered features in production since its beta state. Today, our production apps feature Calendars, Boards, Dashboards, Charts, Timesheet Approvals and more – all done with CMP. It’s helping us deliver consistent, high-quality experiences across platforms while streamlining our development process. With the iOS version now reaching stability, we’re excited to see this technology mature and look forward to expanding its implementation.

“We consider Kotlin Multiplatform validated in our Google Docs experiment […] we consider the experiment a success […] We’re actually very happy with it”

“Starting from this small of a team, it was a huge speed win for X to be able to use Kotlin Multiplatform and write all of that logic once in one place… When you write a bug—not that I ever do that—you only have to fix it in one place.”

Software Engineer at X
Kotlin Multiplatform is a technology that allows you to create applications for various platforms and efficiently reuse code across them while retaining the benefits of native programming. Your applications will run on iOS, Android, macOS, Windows, Linux, and more.
Kotlin Multiplatform is the core technology that lets you share code – such as business logic, data models, networking, and more – across multiple platforms, including Android, iOS, desktop, web, and server. It focuses on code reuse without replacing the native UI unless you want it to.
Compose Multiplatform
is an optional UI framework built on top of Kotlin Multiplatform. It allows you to share your user interface across platforms using a modern, declarative approach similar to Jetpack Compose on Android. You can use it to build visually appealing, responsive UIs for Android, iOS, desktop, and web from a single codebase.
Yes, Kotlin Multiplatform is production-ready for all supported platforms – Android, iOS, desktop, web, and server. Compose Multiplatform is stable for Android, iOS, and desktop, while the web target is currently in Beta.

No. You can start small by sharing a module or feature and integrating it into your existing app. KMP is designed for gradual adoption, making it easy to incrementally introduce cross-platform code.
