This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET
Save, restore or clear the current WebView's storage state: its cookies and its origin's localStorage and sessionStorage, in the shape Vibium saves — {cookies, origins: [{origin, localStorage, sessionStorage}]} — so a state saved by one restores in the other. These call app_storage.
storage
def storage() -> dict
The current page's storage state, in the shape Vibium saves: {"cookies": [...], "origins": [{"origin", "localStorage", "sessionStorage"}]}.
set_storage
def set_storage(state: dict) -> None
Restore a saved state: its cookies, and each origin's storage into the page only if the page is on that origin.
clear_storage
def clear_storage() -> None
Empty the current page's cookies, localStorage and sessionStorage.
Examples
Save the WebView's cookies and web storage
import json
with open("state.json", "w") as f:
json.dump(device.storage(), f)
The same call from the command line, mobium storage -o state.json, printed on an Android 15 emulator:
saved state.json

Restore them in a later run
device.set_storage({"cookies": [], "origins": []})
The same call from the command line, mobium storage restore state.json, printed on an Android 15 emulator:
restored 1 cookie(s) and https://mobiumapp.test's storage
