# CLI Commands

burn0 includes a CLI for setup, reporting, and running your app with cost tracking.

```bash theme={null}
npx burn0 <command>
```

| Command                   | Description                      |
| ------------------------- | -------------------------------- |
| [`init`](/cli/init)       | Interactive setup wizard         |
| [`report`](/cli/report)   | Show cost summary                |
| [`dev`](/cli/dev)         | Run your app with burn0 tracking |
| [`connect`](/cli/connect) | Add your API key                 |
| `status`                  | Show current configuration       |
| `--version`               | Show burn0 version               |

## Live ticker

When your app is running with burn0 imported, a live cost ticker appears on stderr:

```
  burn0 ▸ $4.32 today (47 calls) ── openai: $3.80 · anthropic: $0.52
```

This updates in-place as API calls happen. It doesn't interfere with your app's stdout output.

When the process exits, a session summary is printed:

```
  burn0 ▸ session: $0.47 (12 calls, 4m 22s) ── today: $14.32 ── ~$430/mo
```
