This tool works with both Expo and React Native CLI projects. Just install and go.
Full TanStack Query inspection for React Native. Browse queries, view cached data, simulate states, and debug your data fetching in real-time.
The demo below is the real on-device tool on a mock QueryClient: the cache lights up, a checkout query fails, you inspect cart JSON, force a loading spinner without the network, restore it, then free-play.
Not a video — this is the shipped tool running on a mock QueryClient. Fresh, stale, fetching, inactive, error — every badge the list can show.
npm install @buoy-gg/react-queryThat's it. The React Query DevTools auto-detects your QueryClient and appears in your FloatingDevTools menu.
Data is valid and up-to-date
Data needs to be refetched
Currently loading data
Fetch paused (offline)
No active observers
Query failed
Manually trigger a fetch
Mark query as stale
Reset to initial state
Delete from cache
Simulate loading state
Simulate error state
Simulate loading & error states — Test how your UI handles loading spinners and error boundaries without waiting for real network conditions.
Track all your mutations in real-time:
Simulate offline mode with one tap. The WiFi toggle controls React Query's onlineManager to pause all queries — perfect for testing offline-first features.
The official TanStack devtools are web-only. Install @buoy-gg/react-query and the same capabilities — query browser, cache inspector, state simulation — run inside your app on the device.
Yes. It's pure JavaScript — no native modules — so it works in Expo Go, dev builds, and production.
