Common use cases include Android-to-iOS expansion: share business logic while retaining fully native iOS UI; Full cross-platform mobile apps with shared UI using Compose Multiplatform (Android + iOS + desktop); Cross-platform SDK or library distribution targeting multiple platforms from one Kotlin codebase.

How is Kotlin Multiplatform priced?

Kotlin Multiplatform is free and open-source under the Apache 2.0 license, with source code publicly available on GitHub. There is no cost to use the KMP technology itself. IDE tooling (IntelliJ IDEA, Android Studio) provides free community tiers; JetBrains' commercial IDEs and AI features (AI Assistant, Junie) require paid subscriptions. JetBrains introduced a free AI tier bundled with all IDE licenses starting with the 2025.1 release.

What are the alternatives to Kotlin Multiplatform?

Overview

Kotlin Multiplatform (KMP) is a production-ready, open-source technology developed by JetBrains that enables developers to share Kotlin code across Android, iOS, desktop (Windows, macOS, Linux), web, and server platforms from a single codebase. Reaching stable status in November 2023, KMP compiles to platform-native binaries without runtime bridges or virtual machines, delivering native performance on each target. Developers may share only isolated business logic or leverage Compose Multiplatform to share up to 100% of their app code including UI. A core design principle is incremental adoption—teams can introduce shared modules alongside existing native codebases without full rewrites. KMP has official Google endorsement for Android-to-iOS sharing, with Jetpack libraries migrated to KMP-ready artifacts. Used by over 20,000 companies, including Netflix, McDonald's, Forbes, and Google Workspace, KMP usage among developers more than doubled year-over-year from 7% in 2024 to 18% in 2025.
