There is no universal winner. There is a better fit for your team, timeline, and existing codebase.

When Flutter feels right

Flutter shines when you want a single UI layer with predictable performance and you are starting fresh or can invest in Dart expertise.

The widget model is cohesive. Custom design systems are pleasant to build. You trade ecosystem familiarity for control.

When React Native feels right

If your organization already lives in React and TypeScript, React Native reduces context switching. Shared tooling, hiring, and component patterns can outweigh framework purity.

What I optimize for

I look at team skills first, then product constraints: animation-heavy UI, native module needs, release cadence, and how much platform-specific code you can tolerate.

The best stack is the one your team can ship and maintain without friction.
