One HTTP Client for Android and iOS: Ktor 3 in a KMP Shared Module

The Networking Problem in KMP Projects Before Kotlin Multiplatform, Android had Retrofit and OkHttp while iOS had URLSession or Alamofire — two completely separate networking stacks, two sets of models to keep in sync, and twice the bugs to chase. KMP solves this at the shared-module level, and Ktor Client is the library built specifically for it. One set of API calls, one set of data models,…

The decision between Kotlin Multiplatform vs Flutter vs React Native is the most crucial choice in modern app development. While all three offer code reuse, their core philosophies lead them to excel in vastly different domains:

Kotlin Multiplatform (KMP) is the choice for native performance and enterprise scalability. It champions sharing only the business logic (networking, data, security) in Kotlin, compiling it directly to native binaries. This approach ensures maximum speed, minimal memory overhead, and full access to native APIs on iOS and Android. If your project is AI-heavy, mission-critical, or requires deep OS integration, KMP is the superior architecture, reducing long-term maintenance by centralizing the non-UI code.

Flutter dominates the market for UI consistency and high-fidelity design. Using the Dart language, Flutter builds the entire UI and logic from a single codebase. Its custom rendering engine (Impeller) delivers pixel-perfect, uniform visuals and unmatched performance for animations (up to 120Hz) across all platforms—mobile, web, and desktop. For startups and products where the user experience must be flawlessly consistent and visually rich, Flutter provides the fastest and most reliable path to market.

React Native (RN) is the pragmatic choice for speed and developer efficiency. Leveraging the massive JavaScript ecosystem and the familiar React framework, RN allows web-focused teams to quickly launch applications. Though its performance is competitive with the new Fabric architecture, RN's primary strength remains its low initial cost and rapid iteration cycles, making it ideal for MVPs and lighter, functional applications where an extensive talent pool is prioritized for scaling.

The verdict hinges on alignment: choose KMP for native speed and logic sharing, Flutter for visual perfection, or React Native for rapid, cost-effective scaling with web talent.
