Cross-platform frameworks allow developers to create a single codebase that runs on multiple operating systems—most often iOS and Android—while still delivering native-like performance and a consistent user interface. This approach saves time, reduces costs, and streamlines maintenance, making it a preferred choice for both startups and enterprises aiming for a faster time-to-market.

Here are some real coding examples:

Framework highlights:

• Flutter (Google) uses Dart and a custom rendering engine for highly customizable, smooth apps—used by Google Ads, Alibaba, and Reflectly.
• React Native (Meta) leverages JavaScript and native components, powering apps like Instagram and Skype.
• Kotlin Multiplatform (JetBrains) shares business logic across platforms while allowing native UI, making it ideal for complex projects.
• .NET MAUI (Microsoft) enables cross-platform apps in C# with deep .NET integration, perfect for enterprise solutions.
• Unity is not just for games—it’s used for interactive, cross-platform applications in AR, VR, and simulations.
