Both React Native and Flutter let you ship a single codebase to iOS and Android, and both are production-ready in 2026. The short version: choose React Native if your team works in JavaScript/React or you want to share code with a web app; choose Flutter for pixel-perfect, highly custom UI with identical rendering on every device. For most startups already on React and TypeScript, React Native is the pragmatic default.
Side-by-side comparison
| Dimension | React Native | Flutter |
|---|---|---|
| Language | JavaScript / TypeScript + React | Dart |
| UI rendering | Maps to native platform components | Draws its own widgets (identical everywhere) |
| Performance | Near-native for typical apps | Near-native; edge in heavy custom animation |
| Talent pool | Very large (JS/React) | Smaller but growing |
| Share code with web | Yes — types and logic with React/Next.js | No (Dart doesn't match a JS web stack) |
| Ecosystem | Huge npm library ecosystem | Curated, growing package set |
| Best for | Teams on React; apps sharing a web codebase | Bespoke, brand-heavy, animation-rich UI |
Performance: the honest take
For the vast majority of apps — CRUD, dashboards, social feeds, commerce — both are effectively indistinguishable from native in real use. Flutter's own rendering engine gives it a genuine edge for graphics-heavy, highly custom animation (think games-adjacent UI or complex bespoke visuals). React Native's modern architecture closed most of the historical gap; unless your app is animation-heavy, performance shouldn't be the deciding factor.
Code sharing with your web app
This is React Native's quiet superpower for startups. If you have (or plan) a Next.js web app, you can share TypeScript types and business logic across web and mobile — one source of truth, fewer bugs:
// One shared type, imported by both the Next.js web app
// and the React Native mobile app — a single source of truth.
export type Invoice = {
id: string;
amountCents: number;
status: "draft" | "sent" | "paid";
};
// web (Next.js) and mobile (React Native) both:
import type { Invoice } from "@acme/shared";Pick React Native if
- Your team or existing product is built on React / TypeScript.
- You have (or plan) a web app and want to share types and business logic.
- You want the biggest hiring pool and library ecosystem.
Pick Flutter if
- Your app is UI-heavy with bespoke, brand-driven visuals and animation.
- You need identical rendering across devices with minimal platform quirks.
- Your team is happy to invest in Dart.
What we recommend
We build cross-platform apps in React Native — especially when there's a React or Next.js web app to share types and logic with — so one team ships iOS and Android from a single codebase. It's usually the cheaper path too (see what a mobile app costs). The right answer is the one your team can own and ship fast. Explore our mobile app development service or book a discovery call.
