React Native vs Flutter

React Native uses JavaScript and native UI components, while Flutter uses Dart and its own rendering engine for consistent UI. React Native wins for React teams; Flutter wins on consistency and performance.

Option A

React Native

Option B

Flutter

Key Differences

React Native lets you build apps with JavaScript or TypeScript and the React model. It maps your components to native platform widgets, so apps adopt the platform's look and feel automatically. A major advantage is the ability to reuse skills and some code with React web apps, and to tap the enormous JavaScript ecosystem. Performance has improved as the architecture reduced the overhead of communicating between JavaScript and native code.

Flutter uses Dart and renders everything through its own engine, historically Skia and now increasingly Impeller. Because it draws its own widgets rather than mapping to native ones, UI is pixel-identical across platforms, and Flutter compiles to native code for excellent performance. Its stateful hot reload is outstanding for fast iteration, preserving app state while you edit. Flutter also offers first-party support for mobile, web, desktop, and embedded targets.

The rendering philosophies lead to different trade-offs in look and feel. React Native apps inherit native components, so they feel at home on each platform but can require platform-specific tweaks. Flutter apps look identical everywhere by default, which is great for brand consistency but means matching native conventions takes deliberate effort.

The trade-off is ecosystem familiarity and native UI versus consistent rendering and broad platform reach. React Native appeals to teams invested in React and JavaScript; Flutter appeals to teams wanting consistent UI and strong performance across many platforms.

When to Choose React Native

Choose React Native when your team already knows React or JavaScript, or when you want to share knowledge and some code with a React web application. It is a strong fit when you prefer native platform UI components and want access to the vast JavaScript ecosystem of libraries and tools.

When to Choose Flutter

Choose Flutter when you want pixel-perfect, consistent UI across platforms and top-tier performance. Its single rendering engine and broad platform support make it excellent for teams targeting mobile, web, and desktop from one codebase, with a superb iteration experience thanks to hot reload.

Verdict

Both are mature, capable frameworks. React Native wins for teams in the React ecosystem who want native UI; Flutter wins for consistent rendering, performance, and multi-platform reach. Choose based on language preference and how much UI consistency and platform breadth you need.

1. Upgrade EOL runtime in node-turborepo

End-of-life runtimes no longer receive security patches and block ecosystem upgrades.

./.

>=18.0.0 → 24.0.0 (6 majors behind)

Impact: −10 drift points (runtime & EOL)

2. Fix security posture: no lockfile found

Without a lockfile, installs are non-deterministic. Run the install command to generate one and commit it.

Missing: package-lock.json, pnpm-lock.yaml, or yarn.lock

3. Upgrade Vite 5.4.21 → 8.2.2 in @repo/admin (+2 more)

3 major versions behind. Major framework drift increases breaking change risk and blocks access to security fixes and performance improvements.

Impact: −5–15 drift points

4. Reduce dependency rot in @repo/types (100% severely outdated)

1 of 1 dependencies are 2+ majors behind. Run `npm outdated` and prioritise packages with known CVEs or breaking API changes.

./packages/types

typescript: 5.9.3 → 7.0.2 (2 majors behind)

Impact: −5–10 drift points

5. Reduce dependency rot in @repo/database (75% severely outdated)
