Flutter Vs Kotlin Multiplatform Mobile (KMM) Vs React Native

Tram Ho

In cross-platform development today we have options like Flutter, React Native and now Kotlin Multiplatform Mobile. Now the concern is that we have to choose which of them.

Let us compare these technologies on many different basis.


In case the UI flutter uses the canvas from the native SDK of the different platform and draw the UI component on that canvas using the Material design features. React Native uses native components mapped to js code. And in KMM (Kotlin Multiplatform Mobile), we have to write separate UI code for Android and IOS.

Business Logic

In flutter, react native and KMM and logic are generic but written in different languages ​​dart, js and kotlin respectively.

Layered Architecture

Interoperability (interoperability)

Kotlin can also interact with java and other languages. But in the case of Flutter, we have to just use Dart and React Native we just have to use js.

Easy to go Native (easy to use Native)

In KMM, it’s very easy to write native code at any coding level and at any layer of architecture.

Integration with existing Projects

KMM is capable of integrating with any existing project but not in Flutter or React Native.


Native developers can turn to KMM because from Android’s point of view, Kotlin is the same language they are using in developing Native apps. If KMM is used by an Android developer then the iOS developer has to do a very small task, just create the UI of the App and they will get the logic code from KMM’s share.
