Kotlin Multiplatform
Kotlin Multiplatform — JetBrains framework for sharing Kotlin business logic across Android, iOS, web, and server targets.
Our Verdict
The serious choice for Android-first teams sharing logic to iOS, not a React Native replacement.
Pros
- Share business logic across Android and iOS
- Mature JVM interop and tooling
- Backed by JetBrains and Google
- Compose Multiplatform for shared UI
Cons
- iOS integration still rough around edges
- Smaller ecosystem than React Native
- Debugging cross-platform issues painful
- Build times can be slow
Best for: Android-centric teams wanting to share business logic with iOS without rewriting
Not for: Web-first teams or small shops without Kotlin expertise
