Flutter and Kotlin Multiplatform (KMP) solve cross-platform differently. Flutter shares everything including the UI; KMP shares business logic while you build native UIs. Neither is universally 'better' — it depends on your goals.
Flutter: One Codebase, One UI
- Shares 100% of code including the UI, rendered by its own engine (Impeller).
- Fastest path to a consistent product across iOS, Android, web, and desktop.
- Pixel-identical UI everywhere — great for branded design, occasionally less 'native' feel.
Kotlin Multiplatform: Shared Logic, Native UI
- Shares business logic, networking, and data; UI stays native (SwiftUI / Jetpack Compose).
- Maximum native look-and-feel and easy adoption into existing native apps.
- More platform-specific UI work, but no compromise on platform conventions.
How to Decide
Choose Flutter for greenfield apps where speed-to-market and a unified design matter most. Choose KMP when you have existing native apps, native teams, or need the absolute platform-native experience.
It's Not Always Either/Or
Compose Multiplatform now lets KMP share UI too, blurring the line. Evaluate based on your team's existing skills and how 'native' the UX needs to feel.
