Start the dev environment
After installing expo-air, start everything with one command:
npx expo-air@latest flyThis launches three services and sets up Cloudflare tunnels for remote development:
- Prompt server (port 3847) — WebSocket server connecting the widget to Claude
- Widget Metro (port 8082) — Serves the floating widget UI
- App Metro (port 8081) — Standard Expo Metro for your app code
If you prefer local development without tunnels (e.g., device and Mac on the
same network), you can use npx expo-air@latest start instead. See Remote
Development for more details.
