React vs Flutter: Which One is Better?

Both React and Flutter are powerful technologies used for front-end development, but they serve different purposes. Let’s compare them in detail to determine which is better for your needs.


1. Overview of React & Flutter

🔹 React

  • A JavaScript library developed by Meta (Facebook).
  • Primarily used for web development (React.js).
  • Can also be used for mobile development with React Native.

🔹 Flutter

  • A UI framework developed by Google.
  • Used for cross-platform mobile app development (Android, iOS, Web, Desktop).
  • Uses Dart programming language instead of JavaScript.

2. Key Differences: React vs Flutter

FeatureReact (React.js & React Native)Flutter
Developed ByMeta (Facebook)Google
Programming LanguageJavaScriptDart
Best ForWeb & Mobile (React Native)Mobile (Android, iOS, Web, Desktop)
PerformanceGood, depends on native componentsExcellent, compiled to native code
User InterfaceUses native UI componentsUses custom UI (Skia Engine)
Development SpeedFaster due to JavaScript & large ecosystemSlower initially due to Dart learning curve
Cross-Platform SupportYes (Web & Mobile)Yes (Mobile, Web, Desktop)
Community & SupportLarger (Older)Growing (Newer)
App SizeSmaller (~5MB)Larger (~20MB)
Hot ReloadYesYes (Better performance)

🔹 Winner: Depends on the use case.

  • React → Best for web & mobile (React Native).
  • Flutter → Best for high-performance mobile apps.

3. Performance: Which One is Faster?

🔹 Winner: React → Easier to learn due to JavaScript.


5. When to Use React vs Flutter?

Use React if:

✔ You are building a web app or need React Native for mobile.
✔ You are comfortable with JavaScript.
✔ You need a faster development process with existing libraries.

Use Flutter if:

✔ You want better performance and custom UI.
✔ You are building cross-platform mobile apps.
✔ You are comfortable learning Dart.
