Instant info · optional short probe · Runs in this browser
Use the StorageManager estimate exposed for this origin to show approximate quota and usage. An optional bounded IndexedDB probe writes and reads a temporary block, measures browser storage throughput, verifies the byte count, and deletes the test database.
Review this origin's browser-estimated storage allowance and optionally time one small IndexedDB write/read cycle.
Quota and usage are estimates controlled by the browser and operating system. Private browsing, eviction policy, available disk space, and other origins can change them. The probe database is closed and deleted after every run.
Transparent method
This tool reports only interactions and browser APIs it can observe. It does not infer hidden hardware specifications or turn unsupported access into made-up results.
Useful context
No. It is an approximate allowance for this website's browser storage and can be limited by browser policy, free disk space, privacy mode, and eviction rules.
The probe uses a temporary IndexedDB database and requests deletion after the read test completes or fails.
