Flutter vs React Native for Startups: Which to Choose in 2026
Startups need to ship fast. Both Flutter and React Native deliver cross-platform apps from one codebase. This guide compares them so you can choose the right framework for your startup.
The Short Answer
React Native uses JavaScript/TypeScript and React—ideal if your team already knows web React. Flutter uses Dart—great if you want consistent UI across platforms and a single widget system. Both deliver native-feeling apps; the choice often comes down to team skills and ecosystem needs.
React Native: Pros and Cons
Pros
- JavaScript/TypeScript—familiar to web devs
- Huge ecosystem (npm)
- Used by Meta, Shopify, Discord
- Hot reload for fast iteration
Cons
- •Bridge can add overhead in complex apps
- •Dependency on native modules
- •Some platform quirks to handle
Flutter: Pros and Cons
Pros
- Consistent UI across iOS and Android
- Compiles to native ARM code
- Strong animation support
- Single widget system (Material/Cupertino)
Cons
- •Dart is less common than JavaScript
- •Larger app size
- •Some native integrations need custom code
Which Should Your Startup Choose?
If your team knows React: React Native. If you want maximum UI consistency and don't mind learning Dart: Flutter. For most UK startups, either works—both cut development time by 30-40% versus separate native apps.
