6 Best Cross-Platform App Development Frameworks

Mobile apps have become the cornerstone of user engagement for businesses across sectors. The demand for apps that deliver seamless experiences across multiple platforms is higher than ever. Yet, developing separate native apps for Android and iOS can be time-consuming and resource-intensive, creating a pressing need for more efficient solutions. Cross-platform app development frameworks can redefine the landscape of mobile app development.

Slava Vaniukov, CEO of Softermii, encapsulates this trend succinctly: “Cross-platform frameworks allow companies to be agile in a fast-paced market, ensuring a consistent experience across various platforms while optimizing resource allocation. In many ways, they are making app development more accessible, leveling the playing field.”

What is a Cross-Platform App Framework?

A cross-platform app framework is an SDK that allows developers to create apps compatible with different operating systems – they can write code once and deploy it. This unification accelerates the development process and reduces associated costs.

By 2033, the total market size of cross-platform app development frameworks is expected to reach $546.7 billion.

Key features of cross-platform app development frameworks include:

  • Single codebase ─ It allows developers to write the application logic once, speeding up the development process.
  • UI components ─ These frameworks often come with a library of UI components that automatically adapt to their platform.
  • Access to Native API ─ Cross-platform frameworks often allow apps to use device features like the camera, GPS, and sensors, making them more versatile.
  • Performance optimization ─ You may have seen concerns about the performance of cross-platform apps compared to native apps. Yet, modern frameworks offer robust optimization techniques.
  • Language flexibility ─ Many frameworks support multiple programming languages. They offer developers the freedom to work in a language they are comfortable with.

The Evolution of Cross-Platform App Development Frameworks

With cross-platform frameworks, developers can write code once and deploy it across multiple operating systems. This approach reduces development time and ensures consistency in app performance. Each framework offers unique features, catering to different needs and project requirements.

1. Flutter

Flutter, developed by Google, focuses on providing a customized and visually rich user interface. Unlike other frameworks, it doesn’t rely on native components for rendering. Thus, developers get unprecedented control over the app’s UI and animations. Yet, it may increase the app size due to the need for custom elements. Flutter is an excellent choice for apps that demand a slick, polished appearance.

2. React Native

Originating from Facebook’s engineering team, React Native harnesses the power of JavaScript and React to facilitate mobile app development. React Native may require native modules for some specific functionalities.

Thus, developers can write some components in native languages like Java or Swift. This approach ensures that critical parts of the app run as efficiently as possible. Moreover, React Native offers vast community support and a rich ecosystem of libraries.

3. Kotlin Multiplatform Mobile

Kotlin Multiplatform Mobile (KMM) allows for code sharing between Android and iOS while using native APIs. It allows you to write business logic in Kotlin, but the UI must be developed using native tools, ensuring a high-quality user experience. Thus, each platform will have a separate code for the UI, but your app will feel genuinely native on both.

4. Ionic

Ionic allows for the usage of web technologies like HTML, CSS, and JavaScript to build mobile apps. It wraps web views in a native container, thus achieving cross-platform compatibility. It may not offer the native-like performance seen in other cross-platform app development frameworks. Yet, Ionic speeds up the development process and is a perfect choice for apps like MVPs.

5. Xamarin

Microsoft’s Xamarin framework allows developers to use C# and native libraries wrapped in the .NET ecosystem. Its integration with Azure makes it attractive for companies already committed to the Microsoft stack. Xamarin also promises native-like performance and access to native APIs through bindings.

6. NativeScript

Although less popular than its counterparts, NativeScript offers a blend of native performance and ease of use. It supports Angular and Vue.js, which can be advantageous for teams already familiar with them. Direct access to native APIs also ensures good performance. But, the smaller community and ecosystem may challenge more complex projects.

Why Should Companies Choose Cross-Platform Development?

Regarding mobile app development, the debate between choosing a native or cross-platform approach may occur. Cross-platform frameworks offer distinct advantages, making them an attractive option for developers.

Consistency Across Platforms

A consistent UX across multiple platforms is essential for maintaining brand consistency. Cross-platform frameworks allow developers to use the same design elements for Android and iOS apps. When users switch between platforms, the familiarity of the app’s interface provides a seamless transition. This consistency elevates the brand image and leads to higher customer satisfaction.

Streamlined Development Cycle

One of the arguments for using cross-platform frameworks is the accelerated development cycle. Instead of maintaining codebases for different platforms, developers can focus on one that serves Android and iOS. This approach speeds up the development cycle, enabling quicker iterations and deployments.


Opting for a cross-platform framework can translate into significant cost savings. With the reduced development time, companies can divide their resources more efficiently. For example, they can focus on marketing strategies, user engagement, or exploring new features. All saved time and effort can be redirected into other critical areas contributing to the app’s success.


The landscape of cross-platform mobile app development presents many options tailored to different needs and capabilities. Each framework brings its own set of advantages and limitations. Yet, the benefits make a compelling case for considering cross-platform solutions in many scenarios.

Cross-platform app development frameworks allow for the developing robust, scalable, and efficient mobile apps. They are perfect for companies and developers who want consistent platform experiences.
