---

The `private-gpt` CLI covers the full service lifecycle: starting the HTTP server, launching background workers, and running connected apps like Claude Code.

```
private-gpt <command> [flags]

Commands:
  serve     Start the HTTP server
  worker    Start a background worker process
  run       Launch a connected app (claude-code, openclaw, custom)
  help      Show help for any command
```

---

## serve

Starts the uvicorn HTTP server.

```bash
private-gpt serve [flags]
```

| Flag | Default | Description |
|---|---|---|
| `--host` | `0.0.0.0` | Bind address |
| `--port` | from settings | HTTP port |
| `--reload` | off | Enable auto-reload for development |
| `--log-level` | `info` | `debug` \| `info` \| `warn` \| `error` |
| `--pid-file` | — | Write PID to file (for systemd / launchd) |

**Examples:**

<Tabs>
  <Tab title="macOS / Linux">
    ```bash
    # Start with defaults
    private-gpt serve

    # Development mode with auto-reload
    private-gpt serve --reload --log-level debug

    # Production with PID file for process supervision
    private-gpt serve --pid-file /var/run/private-gpt.pid
    ```
  </Tab>
  <Tab title="Windows (PowerShell)">
    ```powershell
    # Start with defaults
    private-gpt serve

    # Development mode with auto-reload
    private-gpt serve --reload --log-level debug

    # Production with PID file for process supervision
    private-gpt serve --pid-file C:\ProgramData\private-gpt\private-gpt.pid
    ```
  </Tab>
</Tabs>

**PID file behavior:** if `--pid-file` is given and the file already exists with a live process, the command exits with code 1 and prints the existing PID. On `SIGTERM` the PID file is removed.

---

## worker

Starts the Celery worker stack. All behaviour is controlled through environment variables — no CLI flags.

```bash
private-gpt worker
```

`PGPT_WORKER_MODE` is required and selects one registered worker runtime:

| `PGPT_WORKER_MODE` | What starts |
|---|---|
| `arq` | ARQ worker |
| `celery` | Celery worker |
| `flower` | Flower UI only |

**Examples:**

<Tabs>
  <Tab title="macOS / Linux">
    ```bash
    PGPT_WORKER_MODE=celery private-gpt worker

    # Custom concurrency and queues
    PGPT_CELERY_QUEUES=ingest,chat PGPT_CELERY_CONCURRENCY=4 private-gpt worker
    ```
  </Tab>
  <Tab title="Windows (PowerShell)">
    ```powershell
    $env:PGPT_WORKER_MODE = "celery"
    private-gpt worker

    # Custom concurrency and queues
    $env:PGPT_CELERY_QUEUES = "ingest,chat"
    $env:PGPT_CELERY_CONCURRENCY = "4"
    private-gpt worker
    ```
  </Tab>
  <Tab title="Windows (CMD)">
    ```cmd
    set PGPT_WORKER_MODE=celery
    private-gpt worker

    :: Custom concurrency and queues
    set PGPT_CELERY_QUEUES=ingest,chat
    set PGPT_CELERY_CONCURRENCY=4
    private-gpt worker
    ```
  </Tab>
</Tabs>

---

## run

Launches a connected app as a managed child process, automatically injecting the server connection details.

See the [Integrations](/integrations/claude-code) section for app-specific setup guides.

```bash
private-gpt run <app> [flags] [-- <app-args>]
```

| Flag | Default | Description |
|---|---|---|
| `--attach / --no-attach` | auto (TTY detected) | Attach stdin/stdout |
| `--detach` | off | Run in background, print run ID |
| `--session <id>` | — | Resume a previous app session |
| `--model <id>` | `llm.default_model` | Model name (forwarded via env) |
| `--auto-approve` | off | Skip confirmations (CI mode) |
| `--no-server` | off | Skip server detection and auto-start |

**Server auto-start:** before launching the app, `private-gpt run` checks `/health`. If the server is not reachable it starts one automatically and waits up to 60 s. Pass `--no-server` to skip this — useful when the server is managed externally (systemd, Docker).

## help

Show help for any command:

```bash
private-gpt help
private-gpt help serve
private-gpt serve --help
```

Unknown commands print a suggestion:

```
$ private-gpt srve
Unknown command: 'srve'. Did you mean: 'serve'?
```
