Choosing between Flutter and React Native is one of the most critical foundational decisions for any company launching a multi-platform mobile initiative.
Rendering Engines: Impeller vs Native Fabric
Flutter compiles directly to native machine code and renders every pixel via its custom Impeller engine, ensuring identical visual fidelity across all Android and iOS devices. React Native uses the new Architecture (Fabric & TurboModules) to bridge React components directly to native platform views.
When to Choose Flutter:
Complex custom animations, high-frequency canvas drawing, embedded IoT control panels, and pixel-perfect design system parity.
When to Choose React Native:
Existing JavaScript/TypeScript talent, heavy integration with third-party native SDKs, and code-sharing with web Next.js web applications.
