# Debug panel

> Inspect runtime state and troubleshoot application issues on the device

The debug panel is an on-device overlay that displays runtime information for troubleshooting application issues. Use it to inspect data values, generator state, and application behavior directly on the device.

## Open the debug panel

* **From the device** — Open the system menu and tap **Debug Panel**
* **From BRICKS CLI** — Send the action to a device group:

```bash theme={null}
bricks group dispatch <group-id> debug-panel-open
```

To close the panel, tap the close button on the overlay, or dispatch `debug-panel-close`.

## What you can inspect

The debug panel provides real-time visibility into your application's runtime state:

* **Data values** — View current values of data nodes in the active subspace
* **Generator state** — Check generator status, outlet values, and connection state
* **Canvas info** — See which canvas is currently active
