React Native and Flutter dominate cross-platform mobile development in 2026. Both let you build iOS and Android apps from a single codebase, but with different philosophies and trade-offs.
React Native: the JavaScript ecosystem
React Native uses JavaScript/TypeScript and shares logic with React web applications. If your team already knows React, ramp-up is significantly faster.
With Expo, development, builds, and deployment have become much simpler. Apps like DetectGPT and Bot Inbox were built with this stack.
Flutter: performance and consistent UI
Flutter uses Dart and renders its own UI, ensuring visual consistency across platforms. Performance is excellent for complex animations and custom interfaces.
The downside: a smaller Dart ecosystem and a learning curve if the team lacks experience.
When to choose each
Choose React Native if: you already have a React web team, need to share code with Next.js, or want access to the vast npm ecosystem.
Choose Flutter if: UI is highly customized, graphical performance is critical, or you're building a mobile team from scratch.
