Expo vs Flutter
Expo and Flutter both build one codebase that ships to the Apple App Store and Google Play. Expo runs on React Native and JavaScript, so an AI coding tool like Claude Code writes it fluently and EAS Build and Submit send it to both stores from any computer, no Mac required. Flutter uses Dart and its own rendering engine, which gives pixel-perfect control at the cost of a language most AI tools handle less naturally. For a first native app built with Claude Code, Expo is the faster path to live.
Where Expo wins
- Built on React Native and JavaScript, which Claude Code writes fluently from plain-English prompts
- EAS Build compiles in the cloud - no Mac and no Xcode required to ship an iOS app
- EAS Submit pushes to the Apple App Store and Google Play from one command
- Live preview on your real phone in minutes through Expo Go while you build
- Huge React Native ecosystem of libraries for auth, payments, and native features
- The natural fit for the Club's describe-it-build-it method with Claude Code
Where Flutter fits
- Pixel-perfect rendering with its own engine, for precise, consistent UI on every device
- Strong performance and a mature, self-contained widget library out of the box
- Ships to both stores from one Dart codebase, same cross-platform promise
- Excellent tooling if you already know Dart and want tight control over the UI
- A single language and toolchain with no JavaScript bridge to reason about
- Backed by Google with a large, active community and strong documentation
