Frequently asked questions

How do I view and delete IndexedDB data?

Use the IndexedDB Browser tab to browse databases, object stores and records and delete entries. It shows data for this site's origin only.

The Gamepad tab shows live button and axis input from a connected controller.

Battery, clipboard, permissions, gamepad, orientation, screen, network info, storage, notifications, vibration, web share, wake lock, idle detection, IndexedDB, Web Bluetooth, WebUSB, Web Serial, EyeDropper, File System Access, BroadcastChannel and Web MIDI.

Why does an API show as unsupported?

Support differs by browser and device. Many of these APIs, such as Web Bluetooth, WebUSB and Web Serial, work only in Chromium-based browsers and need HTTPS.

Is my data uploaded to a server?

No. This tool runs entirely in your browser — your input is processed locally on your device and is never uploaded or stored on a server.
