When comparing .NET MAUI, Kotlin Multiplatform Mobile (KMM), Flutter, and React Native, several factors need to be considered, including performance, speed, app size, development ease, community support, and platform-specific capabilities. Here’s a breakdown:
Performance and Speed
.NET MAUI: As a part of the .NET ecosystem, it provides near-native performance by compiling to native code. The performance is generally good, but the ecosystem and tooling are still evolving.
Kotlin Multiplatform Mobile (KMM): Offers near-native performance for Android apps since it uses Kotlin, which is the preferred language for Android development. The iOS performance is also good, leveraging Kotlin Native.
Flutter: Uses Dart and compiles to native ARM code for both iOS and Android. Known for high performance and smooth animations due to its custom rendering engine.
React Native: Utilizes a JavaScript bridge to communicate with native modules, which can introduce some performance overhead. However, it provides good performance for most use cases, though it might lag behind Flutter in graphics-intensive applications.
App Size
.NET MAUI: Apps tend to be larger due to the inclusion of the .NET runtime, but ongoing improvements are reducing the overhead.
KMM: The app size is generally optimized as it uses native components and compiles to native binaries, but it can vary depending on the shared code and platform-specific implementations.
Flutter: Flutter apps are usually larger due to the inclusion of the Flutter engine and framework libraries. However, optimizations are regularly being made.

DIVING DEEP
Let's dive deeper into each of these frameworks: .NET MAUI, Kotlin Multiplatform Mobile (KMM), Flutter, and React Native. We'll explore their performance, app size, development ease, community and ecosystem, platform-specific capabilities, and more in detail.
.NET MAUI (Multi-platform App UI)
Performance and Speed
.NET MAUI is the evolution of Xamarin.Forms and part of the larger .NET ecosystem. It aims to provide a single framework for building applications across multiple platforms, including Android, iOS, macOS, and Windows.
Performance:.NET MAUI compiles to native code, which typically results in near-native performance. The framework leverages the Mono runtime on Android and the .NET runtime on iOS, which are highly optimized for performance. Moreover, the use of Ahead-of-Time (AOT) compilation and Just-in-Time (JIT) compilation helps in achieving better performance. Since .NET MAUI uses platform-native UI components, it ensures that the apps are as performant as their native counterparts.
Speed: The speed of .NET MAUI apps can be attributed to several factors, including the use of native UI components, AOT compilation, and the efficiency of the .NET runtime. Additionally, the framework's integration with Visual Studio and other .NET tools can enhance development speed by providing a rich and efficient development environment.
App Size
Apps developed with .NET MAUI tend to be larger due to the inclusion of the .NET runtime and libraries. This overhead is a trade-off for the cross-platform capabilities and the rich set of features provided by the .NET ecosystem. However, Microsoft is actively working on optimizing the app size by trimming unnecessary libraries and components during the build process.
Development Ease
Integrated Development Environment (IDE): .NET MAUI is tightly integrated with Visual Studio, which is one of the most robust IDEs available. Visual Studio provides a comprehensive set of tools for coding, debugging, and testing. The integration allows for features like IntelliSense, code refactoring, and visual designers for building UIs, which significantly ease the development process.
Learning Curve: For developers already familiar with the .NET ecosystem and languages like C#, the learning curve for .NET MAUI is relatively shallow. The framework follows similar patterns and paradigms as other .NET technologies, making it easier for .NET developers to get up to speed.
Cross-Platform Capabilities: .NET MAUI offers a single project structure for building applications across multiple platforms. This structure simplifies the development process by allowing developers to write code once and run it on multiple platforms. Additionally, .NET MAUI provides platform-specific APIs and controls, enabling developers to implement platform-specific features and UI elements when needed.
Community and Ecosystem
Community Support: The .NET community is large and active, with numerous resources, forums, and user groups available for support. Microsoft also provides extensive documentation, tutorials, and sample projects to help developers learn and use .NET MAUI effectively.

Kotlin Multiplatform Mobile (KMM) is a part of JetBrains' Kotlin Multiplatform project, which aims to share code between multiple platforms. KMM specifically focuses on sharing code between Android and iOS.
Performance: KMM offers near-native performance by using Kotlin for both Android and iOS development. On Android, KMM leverages the Kotlin JVM, which provides excellent performance due to its optimized runtime. On iOS, KMM uses Kotlin Native, which compiles to native binaries, ensuring high performance.
Speed: The speed of KMM applications is comparable to native apps since it uses platform-native components and APIs. The shared business logic is compiled to native code, which eliminates the performance overhead associated with interpreted languages.
App Size
The app size in KMM is generally optimized, as it uses native components and compiles to native binaries. However, the app size can vary depending on the amount of shared code and the specific implementations for each platform. JetBrains is continuously working on optimizing the output size to ensure that KMM apps remain lightweight.
Development Ease
Shared Codebase: KMM allows developers to write business logic once and share it across both Android and iOS. This shared codebase significantly reduces the amount of duplicated code and simplifies maintenance. However, the UI code still needs to be written separately for each platform, which can add complexity.
IDE Support: KMM is well-supported in IntelliJ IDEA and Android Studio, providing a familiar development environment for Kotlin developers. These IDEs offer powerful tools for coding, debugging, and testing, along with seamless integration with KMM.
Learning Curve: For developers familiar with Kotlin, the learning curve for KMM is relatively low. The framework follows the same syntax and conventions as Kotlin, making it easier for Kotlin developers to adopt KMM. However, developers need to be comfortable with both Android and iOS development paradigms.
Community and Ecosystem
Community Support: The Kotlin community is active and growing, with a strong presence in the Android development space. JetBrains provides extensive documentation, tutorials, and sample projects to help developers learn and use KMM. The community also contributes to various open-source libraries and tools that support KMM development.
