Flutter and React Native both target iOS and Android from one codebase. The right choice depends on your team, product type and UI requirements.
Quick answer: Flutter is the stronger default for new projects — better performance consistency, more predictable UI across platforms and faster growing enterprise adoption. React Native is the right choice when your team has strong JavaScript/React expertise and you need deep React Native ecosystem integration.
Overview
What is the difference?
Flutter uses Dart and a custom rendering engine (Skia/Impeller) to render UI natively on both platforms — producing consistent, high-performance apps. React Native bridges JavaScript to native components, giving access to the native UI layer but introducing bridge overhead and platform inconsistencies.
Comparison
Feature-by-feature comparison
Flutter vs React Native across the dimensions that matter most.
Feature
Flutter
React Native
Language
Dart — purpose-built for UI, easy to learn.
JavaScript / TypeScript — familiar to web developers.
Rendering
Custom rendering engine — UI is identical on all platforms.
Near-native — rendering bypasses the JavaScript bridge.
Good — improved with the new architecture (JSI).
UI consistency
Pixel-perfect identical UI across iOS and Android.
Platform-native look — may differ between iOS and Android.
Ecosystem
pub.dev — growing, strong for mobile-first packages.
npm — largest JavaScript ecosystem available.
Web and desktop
Supported — single codebase to web, desktop, mobile.
React Native Web available but less mature.
Enterprise adoption
Growing — Google, BMW, eBay use Flutter in production.
Mature — Meta, Microsoft, Shopify in production.
Learning curve
Moderate — Dart is new but simple for developers.
Lower for JS/React developers — familiar paradigm.
Decision guide
When to choose each
Choose Flutter when:
You want pixel-perfect UI consistency across iOS and Android.
Your team is building from scratch and can adopt Dart.
You need web or desktop targets alongside mobile from one codebase.
Performance consistency is a priority — especially for animation-heavy apps.
Choose React Native when:
Your team has strong JavaScript or React expertise.
You need deep integration with native platform components.
You are adding mobile to an existing React web codebase.
Your npm-ecosystem dependencies are a core part of the product.
Cost
Cost comparison
Flutter
Flutter development cost is similar to React Native for a given scope. One codebase reduces long-term maintenance cost versus two separate native apps.
React Native
React Native development cost is similar to Flutter. Large teams already in JS may benefit from lower onboarding cost.
Performance
Flutter consistently achieves 60fps on modern devices because the rendering engine bypasses the JavaScript bridge. React Native's new architecture (JSI) closes the gap significantly — both are suitable for production apps when implemented correctly.
Security
Both frameworks have comparable security profiles. Security depends on implementation — how credentials are stored, how APIs are called and how the app handles sensitive data — not the choice of framework.
