Short answer
Choose Flutter when you want pixel-consistent custom UI, smooth animations and one team owning iOS, Android and possibly desktop. Choose React Native when your team already knows React and JavaScript or TypeScript, you want to share logic with a React web app, or you rely on native modules. Both produce production-quality apps at similar cost.

Choose Flutter if…
Your app is design-heavy with custom UI and animation, you want identical look on every device, or you plan desktop and embedded targets too.
Choose React Native if…
Your team knows React, you have a React or Next.js web app to share code with, or you need many native SDKs and want the larger JavaScript ecosystem.
Side-by-side comparison
| Factor | Flutter | React Native |
|---|---|---|
| Backed by | Meta and the open-source community | |
| Language | Dart | JavaScript or TypeScript |
| UI | Draws its own widgets, so UI looks identical on every device | Uses native platform components, so UI follows each platform |
| Performance | Excellent, compiled to native code with its own rendering engine | Excellent for most apps since the New Architecture removed the old bridge |
| Code sharing with web | Flutter web works, but suits app-like experiences more than SEO sites | Strong when paired with React or Next.js web apps |
| Hiring | Growing pool of Dart developers | Very large pool of React and JavaScript developers |
| Native features | Plugins for most needs; platform channels for the rest | Large module ecosystem; native modules for the rest |
| Best fit | Brand-heavy consumer apps, custom design systems, multi-platform | Teams with React skills, apps tied to a React web product |
Cost and maintenance
Build cost is usually within a similar range for the same scope, because both share most code between iOS and Android. A typical cross-platform app costs USD 15,000–60,000 depending on features; see the app development cost calculator.
Over the long term, the bigger cost driver is your team: a framework your developers know well is cheaper to maintain than the theoretically better one. Factor in who will maintain the app after launch, in-house or with a dedicated team.
When neither is right
- Heavy native features, such as advanced camera processing, AR or deep OS integration, may justify fully native Swift and Kotlin apps. See native vs cross-platform apps.
- Content and SEO-driven products may be better as a fast website or progressive web app first. See PWA vs native app.
