Kotlin Multiplatform Framework (KMP) 


KMP offers a balanced approach to cross-platform mobile development by combining the efficiency of code sharing with the ability to stay ‘native’ where it matters the most – the UI. Therefore, KMP is a powerful tool for businesses aiming to deliver high-quality mobile experiences across different platforms efficiently. 


  • Kotlin is a statically typed programming language, interoperable with Java 
  • allows building cross-platform client applications, multi-platform libraries and full-stack applications that utilize shared code between frontend and backend 
  • sharing code between different platforms, specifically for mobile development  
  • enabling developers to write the business logic once in Kotlin and reuse it across multiple platforms (iOS, Android), while keeping the flexibility to create platform-specific UI 
  • this results in less time and effort spent on writing and maintaining the same code for different platforms 



Flutter offers a powerful, efficient, and cost-effective solution for cross-platform mobile application development, ensuring a consistent, beautiful UI, and a native app performance. It’s dedicated for businesses aiming to deliver high-quality mobile experiences quickly and efficiently


  • uses Dart, a modern, object-oriented programming language offering robust performance. 
  • allows building high-quality native interfaces on iOS and Android from a single shared codebase 
  • provides the same UI across different platforms thanks to  widget system, which ensures that the app’s UI looks and feels beautiful and is consistent across all devices 
  • hot-reload feature allows developers to see the changes in the code almost instantly, without losing the current application state 
  • overall, allows for faster iterations, quick bug fixes, and a more efficient development process
