React Native vs Flutter: Which Should You Choose?

We build our own mobile app, the BrokLeads app (in early access), with React Native and Expo. So this comparison draws on that for React Native, and on Flutter's own documentation for the rest. Here's how we think about the choice.

The Short Answer

Both are good options. If you've read a comparison that declares one clearly better for everything, be sceptical. The real question is which fits your specific situation — and that comes down to your team's background, your timeline, and what you're building.

Performance: The Real Story

Flutter compiles Dart ahead of time to native code and draws every pixel itself, using its Impeller renderer. React Native runs JavaScript and drives real native UI components, historically through a bridge and now through JSI (the JavaScript Interface) in the New Architecture.

In animation-heavy, graphics-intensive work, Flutter's own renderer can have the edge. For most business apps (dashboards, e-commerce flows, booking systems, lead lists), both are fast enough that the difference rarely shows.

React Native's New Architecture closed much of the gap. JSI removes the serialisation overhead of the old bridge. It became the default for new projects in React Native 0.76, and Expo turned it on by default for new projects from SDK 52.

The Ecosystem Question

React Native's biggest advantage is JavaScript. Your team can share utility functions, state management logic, and tooling with your web codebase. If you use React Query on the web, you can use it in your React Native app. If you have web developers, the ramp-up to React Native is days, not weeks.

The npm ecosystem is massive, but that's a double-edged sword. You'll occasionally hit packages that haven't been updated in two years or have poor native module support. This has improved a lot, but it still happens.

Flutter's pub.dev ecosystem is smaller, and many of its core packages are maintained by the Flutter team itself. The tradeoff is that for niche requirements — unusual hardware integrations, specific payment SDKs — you may find React Native has better community support simply due to volume.

Developer Experience

React Native with Expo is pleasant to work with. You can be running on a real device quickly, Expo Router brings file-based routing to mobile, and the tooling (ESLint, Prettier, TypeScript) is the same as on the web. EAS handles cloud builds and store submissions.

Flutter's developer experience is also strong. Hot reload is fast, and Dart is easy to pick up if you know TypeScript. The widget-tree model is different from web development and takes a mental shift, but many developers find its layout system more predictable than CSS once they've learned it.

The honest friction point with Flutter: it's another language, another package manager, another set of idioms. If your team is full-stack JavaScript/TypeScript, that's a real cost to consider.

Hiring and Team Fit

This is underrated in most comparisons. React Native developers are easier to find because JavaScript developers are everywhere. If you need to grow the team quickly or bring in contractors for a sprint, React Native usually wins. Flutter and Dart developers are a smaller pool, though a growing one.

When to Choose React Native

• You have a JavaScript/TypeScript team or a shared web and mobile codebase
• You need to integrate with third-party JavaScript SDKs (analytics, payments, support)
• Fast hiring or contractor work is likely in your future
• You're using Expo for a managed workflow with OTA updates
• Your app has standard UI patterns: lists, forms, navigation, cards

When to Choose Flutter

• Custom, pixel-perfect UI is a core product requirement — not just a nice-to-have
• You're targeting multiple platforms from a single codebase (iOS, Android, web, and desktop)
• Your team is comfortable with Dart or has the time to invest in learning it properly
• Consistent rendering across every Android device is non-negotiable for your brand
• You're building something animation-heavy, like an interactive onboarding flow or a design tool

Our Recommendation

For most startups and business apps: React Native with Expo. The ecosystem, hiring pool, and JavaScript familiarity make it the pragmatic choice for getting to market quickly and iterating fast.

For projects where the interface is the product, the visual experience is the differentiator, and your team is willing to invest in Dart, Flutter is worth it. Because it draws everything itself, it renders the same way on every device.

One more thing: don't let this decision paralyze you. Both are production-ready, both have large communities, and both can build the same apps. A mediocre implementation in either framework will underperform a well-built app in the other. Pick the one your team is more excited about, ship fast, and iterate.
