Cross-Platform vs Native: React Native and Flutter in Practice

Sneha IyerMobile Engineer1 min read

Once the decision to build a native app is made, the next question is whether to actually build two separate native codebases or one cross-platform codebase with React Native or Flutter — and for most projects we take on now, cross-platform is the right default, with native reserved for specific, real reasons.

Why cross-platform wins for most projects

  • One codebase means one team, one set of bugs to fix, and features that ship to both platforms at the same time instead of twice, on separate timelines.
  • The performance gap with fully native has narrowed enough that most apps' users would never notice the difference in practice.
  • Both major frameworks now have mature ecosystems, meaning most common needs are already solved by existing libraries rather than requiring custom native code.

When fully native is still the right call

Apps that are almost entirely built around a specific platform capability — deep camera processing, complex animations tightly tied to platform-specific APIs, or performance-critical work like gaming — still benefit from native development. This is the same requirements-first thinking behind any tech stack decision: the framework should follow from what the app actually needs to do, not from what's trendiest.

Most users can't tell you whether an app is native or cross-platform. They can absolutely tell you whether it's slow, buggy, or missing the feature the other platform got first.

For the large majority of mobile app projects worth building at all, cross-platform gets you to market faster, keeps both platforms in sync, and rarely costs users anything they'd actually notice.
