Introduction
In 2025, Kotlin Multiplatform (KMP) is no longer an experimental feature—it’s a mature, powerful approach to cross-platform development. Whether you’re looking to save time, reduce duplication, or maintain truly native experiences across platforms, KMP is emerging as a go-to solution.
1. What Is Kotlin Multiplatform (KMP)?
Kotlin Multiplatform—also known by its legacy term Kotlin Multiplatform Mobile (KMM)—is an open-source technology by JetBrains that allows you to share core business logic across Android, iOS, web, desktop, and server platforms while preserving truly native UIs and performance. It uses expect/actual declarations to write shared logic (data access, networking, serialization) in Kotlin and implement platform-specific behavior as needed.
2. Why Kotlin Multiplatform Is Trending in 2025
Production-ready and backed by leaders: KMP moved out of beta and became production-ready in late 2023, earning support from JetBrains and Google.
Significant adoption: Companies like Netflix, McDonald’s, Cash App, VMware, Philips, Forbes, Autodesk, and Baidu are leveraging KMP in production.
Compose Multiplatform is maturing fast: JetBrains targets a stable Compose experience across platforms in 2025, including iOS, desktop, and web.
3. Benefits of Kotlin Multiplatform
| Benefit | Why It Matters |
|---|---|
| Max Code Reuse, Native UX | Share business logic in Kotlin, keep platform-specific UI native. |
| Efficiency & Maintainability | Fix once, deploy everywhere—simpler QA and faster iterations. |
| Familiar developer experience | Android engineers can continue using Kotlin; iOS teams use Swift/Kotlin. |
| Composable UI sharing with Compose Multiplatform | Start sharing UI code across Android, desktop, web, soon iOS. |
4. KMP vs Flutter & React Native
| Feature / Aspect | Kotlin Multiplatform (KMP) | Flutter | React Native |
|---|---|---|---|
| Code Sharing Scope | Business logic sharing (UI optional with Compose Multiplatform) | Full UI + logic via Dart SDK | UI + logic via JavaScript bridge |
| User Interface (UI) | 100% native UI (Android/iOS codebases) | Flutter widgets mimic native look & feel | Bridge-based UI (sometimes less fluid) |
| Performance | Near-native (minimal overhead) | High, but Flutter UI is rendered with its own engine | Moderate (JS bridge adds latency) |
| Tooling & Ecosystem | Works in Android Studio, Xcode, JVM; leverages Kotlin ecosystem | Requires Dart SDK + Flutter toolchain | Tied to JavaScript ecosystem (Node, React) |
| Best Use Cases | Enterprises with existing Kotlin code, apps needing deep native UX | New apps requiring unified UI and fast prototyping | Web-first teams expanding into mobile |
| Learning Curve | Easy for Android/Kotlin devs; iOS devs need Kotlin basics | Requires learning Dart + Flutter | Easier for React/JS developers |
| Industry Adoption (2025) | Used by Netflix, Cash App, McDonald’s, VMware, Philips | Google, BMW, eBay, Toyota, Alibaba | Facebook (Meta), Instagram, Shopify, Tesla |
5. Real-World Success Stories
Leading companies using KMP in production include:
Netflix – shares internal video tooling logic across Android & iOS
VMware – unified networking/authentication, reduced time-to-market by ~40%
Others: Cash App, Memrise, McDonald’s, Philips, Baidu, Forbes, Autodesk, Careem, XAPO Bank
6. Production-Ready? Absolutely.
In 2025, KMP is established and trusted. JetBrains has refined tooling, documentation, and Compose Multiplatform is edging toward full stability. Real-world usage proves its maturity across various industries.
7. Getting Started with Kotlin Multiplatform
Master Kotlin fundamentals: Coroutines, higher-order functions, etc.
Create a KMP project: Set up
commonMain,androidMain,iosMain, etc.Use
expect/actual: Share logic and write platform-specific parts.Adopt Compose Multiplatform: Share UI across platforms with Jetpack-style declarative syntax.
Use robust libraries: e.g., Ktor for networking, SQLDelight for storage, kotlinx.serialization, Koin or Napier for DI/logging.
Learn from existing samples: JetBrains’ KMP examples and “Awesome KMP” on GitHub.
Include case studies & benchmarks: Highlight comparisons like KMP vs Flutter.
8. Pitfalls & Considerations
Still growing: Some Compose iOS components are in alpha.
Library ecosystem is leaner: Not as many plug-and-play options as Flutter/React Native.
Requires cross-platform and native expertise: Teams need Kotlin and Swift/Xcode proficiency.
Kotlin Multiplatform is no longer an experiment—it’s a mature, efficient, and native-grade solution for cross-platform apps. With its strong ecosystem support, growing adoption by industry leaders, and the rise of Compose Multiplatform, now is the perfect time to explore KMP for your next project.
