Browse AsyncStorage, MMKV, and SecureStore in one place

Buoy Storage shows every key-value pair your app persists, across AsyncStorage, MMKV, and SecureStore, live on the device. Watch writes happen in real time, diff versions of a value, spot keys your app expects but never wrote, and edit values in place to test edge cases.

Declare the keys your app expects and instantly spot ones that were never written — initialization bugs surface in seconds.

Live events timeline

Every storage operation as it happens: what changed, when, and how often each key is written.

Diff and split views

Compare previous and current values side by side, with a tree view of exactly what each operation modified.
