Senior cross-platform developer rates in 2026: US-based $80-$160/hour, Eastern Europe $40-$90/hour, Latin America $35-$85/hour, India / Pakistan / Vietnam $25-$70/hour.

Both ship production-grade apps. React Native wins on developer-pool size, JS ecosystem fit, and gentler ramp for web teams. Flutter wins on pixel-perfect UI consistency and animation-heavy apps. We help you pick based on your team, target platforms, and design priorities — not based on framework preference.
