Cross-platform Explored: React Native vs Xamarin vs Flutter

React Native vs Xamarin vs Flutter

The mobile app market thrives on diversity. From social media giants to niche productivity tools, users have options for practically any need. But for developers, catering to this vast demand can be a challenge.

Traditionally, building an app meant creating separate versions for each primary operating system – Android and iOS. This doubles (or triples if you consider desktop apps) the workload and resources required.

Thankfully, the world of cross-platform development offers a compelling solution. Developers can create apps that run seamlessly on different platforms using a single codebase. This translates to faster development times, reduced costs, and broader reach for your app.

But with so many cross-platform frameworks available, choosing the right one can be tricky. Three of the most popular options are React Native, Xamarin, and Flutter. Each has its own strengths, weaknesses, and ideal use cases.

So, how do you decide which framework is the best fit for your project? 

In this blog series, we’ll explore the specifics of React Native, Xamarin, and Flutter and compare their features, performance, and suitability for different types of apps. 

By the end, you’ll be well-equipped to make an informed decision and conquer the challenge of building apps for today’s diverse mobile landscape.

What Are Cross-Platform Frameworks?

Cross-platform frameworks are essentially time-saving superpowers for mobile app developers. 

Instead of building separate apps from scratch for each operating system, such as Android and iOS, these frameworks allow developers to create a single codebase that can be deployed across multiple platforms. 

This translates to significant advantages for both developers and users:

  • Faster development and lower costs: Reusing code across platforms means less time spent writing and debugging, which saves development resources and shortens the time it takes to get your app to market.
  • Wider audience reach: With a single codebase, you can target a broader user base by making your app available on both Android and iOS without the extra effort of building separate versions. This translates to potentially more users and increased visibility for your app.
  • Simplified maintenance: Imagine managing updates and bug fixes for just one codebase instead of multiple ones. Cross-platform frameworks streamline the maintenance process, making it easier to keep your app up to date-and functioning flawlessly across all platforms.

What is Flutter And Its Key Features

Flutter is an open-source framework created by Google for building beautiful, fast mobile apps. But it’s not limited to just mobile! One of its key strengths is that it allows you to code using a single codebase to create apps for multiple platforms, including:

  • Mobile (Android & iOS)
  • Web
  • Desktop (Windows, MacOS, Linux)

Here are some of the key features that make Flutter so popular:

  • Single codebase: This is a big time-saver for developers, allowing them to write code once and deploy it across multiple platforms.
  • Hot reload: This feature lets you see changes to your code reflected in the app almost instantly, speeding up the development process.
  • Custom Widgets: Flutter’s widget-based UI allows for a high degree of customisation and flexibility in designing app interfaces.
  • Dart language: Flutter uses Dart, a modern object-oriented language known for being easy to learn, even for developers unfamiliar with it.
  • Native-like performance: Apps built with Flutter perform smoothly and feel just like native apps, regardless of the platform.

Overall, Flutter is a robust framework that can help Flutter developers create high-quality apps efficiently.

What Is Xamarin And Its Key Features

Xamarin, another famous player in the cross-platform app development arena, is a Microsoft-owned framework that Xamarin developers that you will hire you to build native iOS, Android, and Windows apps using C#. 

Like Flutter, it offers a single codebase approach to streamline development and reach a wider audience. 

Here’s a breakdown of Xamarin’s key features:

  • Cross-platform development with C#: Developers can leverage their existing C# knowledge to create apps for multiple platforms, reducing the learning curve and development time.
  • Native experience: Xamarin apps have access to native APIs and UI elements, ensuring they look and feel indistinguishable from native apps on each platform.
  • Xamarin.Forms: This feature allows for building UIs with a single codebase that gets translated to platform-specific elements at runtime. It’s great for business apps but might have a slight performance trade-off compared to fully native development.
  • Visual Studio integration: Xamarin integrates seamlessly with Visual Studio, a familiar and feature-rich IDE that developers already love.
  • Xamarin.Essentials library: This library provides a unified API for accessing standard device features like cameras, sensors, and geolocation across all supported platforms.

What Is React Native And Its Key Features

React Native, a brainchild of Facebook, is an open-source framework that empowers developers to build native-looking mobile apps for iOS and Android using JavaScript and React. 

Just like the other cross-platform frameworks, it offers a single codebase approach but with its own distinct advantages:

  • JavaScript expertise leverage: Developers with existing JavaScript knowledge can jump right into React Native development, reducing the learning curve and speeding up the app creation process.
  • Declarative UI paradigm: React Native uses a declarative UI paradigm. You describe the UI’s appearance, and React Native handles the rendering on each platform. This simplifies development and promotes maintainable code.
  • Reusable components: React Native encourages building reusable components that can be easily shared across different parts of your app or even in entirely different projects. This promotes code modularity and consistency.
  • Third-party library ecosystem: React Native benefits from a vast ecosystem of third-party libraries and plugins that provide pre-built functionality for various needs. This saves developers time by avoiding building everything from scratch.
  • Hot reloading: Similar to Flutter’s hot reload feature, React Native development allows you to see changes in your code reflected in the app almost instantly, accelerating the development workflow.

Which Croos-Development Framework You Should Choose?

There’s no one-size-fits-all answer to which cross-platform framework is best for a business. The ideal choice depends on several factors specific to your project and development team. 

Here’s a breakdown to help you decide:

React Native:

Good choice if:

  • Your team has strong JavaScript expertise.
  • Development speed and cost-effectiveness are top priorities.
  • The app is business-oriented and doesn’t require ultra-high performance.

Things to consider:

  • While performance is good, it might not match genuinely native apps.
  • The user interface might have some subtle differences from native apps.


Good choice if:

  • Your team has a C# background.
  • Targeting native-like performance is crucial for your app.
  • You want to leverage Visual Studio for development.

Things to consider:

  • The learning curve can be steeper for developers unfamiliar with C#.
  • Xamarin.Forms might have slight performance trade-offs compared to fully native development.


Good choice if:

  • You want a framework with a modern language (Dart) and excellent documentation.
  • Your app requires a high degree of UI customisation with custom widgets.
  • Fast development and hot reload features are appealing.

Things to consider:

  • The Flutter developer community is growing but might be smaller than React Native or Xamarin.
  • Dart is a relatively new language, so finding developers familiar with it might be challenging.
