In the world of cross-platform mobile app development, React Native and Kotlin Multiplatform have emerged as popular choices for developers. These frameworks enable developers to write code once and deploy it on multiple platforms, saving time and effort. In this guide, we will compare React Native and Kotlin Multiplatform and explore their key features, advantages, and limitations in 2023.

React Native:

React Native, developed by Facebook, has gained significant traction since its release. It allows developers to build mobile apps using JavaScript and leverages the power of the React framework. React Native boasts a large and active community, offering extensive documentation, libraries, and tools.

One of the main advantages of React Native is its ability to provide a native-like user experience. It achieves this by rendering UI components using native elements, resulting in smoother animations and faster performance. React Native also supports hot reloading, allowing developers to see real-time changes in their app without restarting it.

In terms of third-party libraries, React Native has a vast ecosystem, offering various options for different use cases. When it comes to React Native chart libraries, React Native provides several options such as React Native Chart Kit, Victory Native, and react-native-svg-charts. These libraries enable developers to create visually appealing and interactive charts, catering to different data visualization needs.

However, React Native does have some limitations. Since it uses JavaScript, which is an interpreted language, the performance may not match that of native code written in languages like Kotlin or Swift. Additionally, React Native’s reliance on native components may cause issues when accessing certain platform-specific functionalities.

Kotlin Multiplatform:

Kotlin Multiplatform, developed by JetBrains, is gaining popularity as a robust cross-platform framework. It allows developers to write shared business logic using Kotlin and then compile it into native code for different platforms, including Android, iOS, and even web applications.

One of the key advantages of Kotlin Multiplatform is its seamless integration with existing Android projects. Developers can easily leverage their existing Kotlin skills and codebase, making the transition to Kotlin Multiplatform relatively smooth. It also provides direct access to platform-specific APIs and libraries, allowing developers to utilize all the native capabilities of each platform.

While Kotlin Multiplatform does not have as large a community as React Native, it is rapidly growing, and more developers are adopting it. Kotlin Multiplatform benefits from Kotlin’s modern features, such as null safety, coroutines, and extension functions, enhancing developer productivity and code quality.

In terms of chart libraries, Kotlin Multiplatform offers a range of options as well. Libraries like MPAndroidChart and Kotlin Multiplatform Charts provide rich and customizable charting capabilities, enabling developers to create stunning visualizations across multiple platforms.

When it comes to performance, Kotlin Multiplatform shines. Since the code is compiled into native code for each platform, it can achieve near-native performance. This makes it an excellent choice for performance-critical applications.

In addition to the considerations mentioned above, it’s important to note that React Native and Kotlin Multiplatform also have different approaches to UI development.

React Native follows a declarative UI approach, where developers describe the desired UI state, and React Native handles the rendering and updates accordingly. This approach simplifies the UI development process and enables rapid prototyping. React Native also provides a wide range of pre-built UI components, making it easier to create consistent and visually appealing interfaces.

Kotlin Multiplatform, on the other hand, allows developers to use platform-specific UI frameworks directly. For example, on Android, developers can use XML layouts and the Jetpack Compose UI toolkit, while on iOS, they can use Interface Builder and SwiftUI. This allows for more fine-grained control over the UI and takes advantage of the native tools and frameworks available on each platform.

When considering chart libraries specifically for React Native, there are several popular options available. React Native Chart Kit is a widely used library that supports various chart types, including line charts, bar charts, and pie charts. It offers extensive customization options and is compatible with both iOS and Android platforms. Victory Native is another powerful charting library for React Native, providing a rich set of features and a declarative API for creating beautiful charts. Additionally, react-native-svg-charts leverages SVG (Scalable Vector Graphics) to create interactive and visually appealing charts.

For Kotlin Multiplatform, MPAndroidChart is a highly regarded library that originated in the Android ecosystem but has been adapted to work with Kotlin Multiplatform projects. It offers a wide range of chart types and customization options and has excellent performance characteristics. Kotlin Multiplatform Charts, on the other hand, is a dedicated charting library built specifically for Kotlin Multiplatform projects. It supports multiple platforms and provides a consistent API for creating charts, making it easier to share code across different platforms.

Both React Native and Kotlin Multiplatform have their strengths and weaknesses when it comes to cross-platform mobile app development. React Native offers a familiar development experience and a robust ecosystem, while Kotlin Multiplatform leverages the power of Kotlin and provides direct access to platform-specific APIs. When it comes to chart libraries, React Native has options like React Native Chart Kit, Victory Native, and react-native-svg-charts, while Kotlin Multiplatform offers MPAndroidChart and Kotlin Multiplatform Charts. Choosing the right framework and chart library depends on various factors, including project requirements, performance considerations, community support, and the desired level of control over the UI.


React Native and Kotlin Multiplatform have their strengths and weaknesses. React Native provides a familiar development experience for web developers and offers a vast ecosystem of libraries. It excels at delivering a native-like user experience but may suffer from performance limitations.

On the other hand, Kotlin Multiplatform leverages the power of the Kotlin language and offers seamless integration with existing Android projects. It provides access to platform-specific APIs and delivers high-performance code. However, it may require developers to learn Kotlin if they are not already familiar with it.

When it comes to chart libraries, both frameworks offer compelling options. React Native chart libraries like React Native Chart Kit and Victory Native provide a wide range of features, while Kotlin Multiplatform libraries like MPAndroidChart and Kotlin Multiplatform Charts offer performance and flexibility.

Ultimately, the choice between React Native and Kotlin Multiplatform depends on your specific project requirements, existing skill sets, and preferences. It is essential to evaluate the trade-offs and consider factors such as performance, community support, and platform integration to make an informed decision in 2023.
