Pros and cons of using cross-platform development frameworks

Like any solution, multiplatform frameworks have their pros and cons. Here’s a list of the ones you should pay the most attention to.

Benefits of cross-platform app development frameworks

  • Wider reach: With a single codebase, your app can run on multiple platforms, significantly expanding your potential user base.
  • Cost-effective: Save on development and maintenance costs by avoiding separate builds for each platform.
  • Consistency in UI/UX: Ensure a uniform experience across all platforms, which can strengthen brand identity and user satisfaction.
  • Faster development time: Reuse code across platforms to speed up the development process and get to market quicker.
  • Simplified deployment: Streamline the process of updating and deploying your app, making it easier to manage.
  • Unified maintenance: Maintenance becomes more manageable with a single codebase, reducing the need for parallel updates and cutting costs.
  • Vibrant community support: Benefit from the extensive resources, tools, and community expertise available for popular frameworks.

Challenges in cross-platform app development frameworks:

  • Performance overhead: Generally speaking, a native app might edge out a cross-platform counterpart in speed if both share identical features, simply due to its direct integration with the operating system. Yet it’s worth noting that, for most applications, this performance gap is often minimal, ensuring that cross-platform apps remain competitive in terms of speed and efficiency.
  • Platform-specific limitations: Some native functionalities can be challenging to implement, potentially leading to compromises in feature sets. However, to overcome this challenge, you can integrate native modules by writing platform-specific code (Java/Kotlin for Android, Swift/Objective-C for iOS) for unsupported features. In addition, you can use third-party libraries and plug-ins to fill feature gaps and increase feature compatibility across platforms. These tools, often developed by the community or officially provided, are essential to improving the overall feature set across platforms.
  • Delayed access to new features: When it comes to incorporating the latest platform-specific features, cross-platform apps require a strategic approach. The interval between a new feature’s release by platform giants like Google or Apple and its adoption into cross-platform frameworks is a testament to the careful integration and testing aimed at maintaining app integrity across ecosystems. This ensures that, when new updates are rolled out, they’re not just fast but also fully optimized for a cross-platform environment.

The future of cross-platform app development

The landscape of cross-platform solutions is dynamic, with new competitors emerging and others fading away. For example, on May 1, 2024, Microsoft ended support for Xamarin, their cross-platform framework, marking the end of an era for a once-popular tool.

But Microsoft isn’t abandoning cross-platform altogether. Instead, they are replacing Xamarin with .NET MAUI, a newer and more advanced cross-platform framework. NET MAUI promises better performance, increased productivity, and a more streamlined developer experience than Xamarin. It is also built on .NET 6, which brings improved performance and features across all platforms.

In contrast, Kotlin Multiplatform is showing potential, even if it’s not as widely adopted. It has already gained recognition from some industry giants, making its growth trajectory one to watch.

For the time being, however, Flutter maintains its lead, a position it has consolidated over the past few years.
