## Hetzner Cloud

Spawn agents on [Hetzner Cloud](https://www.hetzner.com/cloud/) servers. No `hcloud` CLI needed — uses the Hetzner REST API directly.

### Usage

#### Claude Code

```bash
bash <(curl -fsSL https://openrouter.ai/lab/spawn/hetzner/claude.sh)
```

### Non-Interactive Mode

```bash
HETZNER_SERVER_NAME=dev-mk1 \
HCLOUD_TOKEN=your-hetzner-api-token \
OPENROUTER_API_KEY=sk-or-v1-xxxxx \
bash <(curl -fsSL https://openrouter.ai/lab/spawn/hetzner/claude.sh)
```

**Environment Variables:**
- `HETZNER_SERVER_NAME` - Name for the server (skips prompt)
- `HCLOUD_TOKEN` - Hetzner Cloud API token (skips prompt, saved to `~/.config/spawn/hetzner.json`)
- `OPENROUTER_API_KEY` - Skip OAuth and use this API key directly
- `HETZNER_SERVER_TYPE` - Server type (default: `cx22`)
- `HETZNER_LOCATION` - Datacenter location (default: `fsn1`)

## Hetzner Cloud

Spawn agents on [Hetzner Cloud](https://www.hetzner.com/cloud/) servers. No `hcloud` CLI needed — uses the Hetzner REST API directly.

### Usage

#### Claude Code

```bash
bash <(curl -fsSL https://openrouter.ai/lab/spawn/hetzner/claude.sh)
```

### Non-Interactive Mode

```bash

**Environment Variables:**
- `HETZNER_SERVER_NAME` - Name for the server (skips prompt)
- `HCLOUD_TOKEN` - Hetzner Cloud API token (skips prompt, saved to `~/.config/spawn/hetzner.json`)
- `OPENROUTER_API_KEY` - Skip OAuth and use this API key directly
- `HETZNER_SERVER_TYPE` - Server type (default: `cx22`)
- `HETZNER_LOCATION` - Datacenter location (default: `fsn1`)

## Hetzner Cloud

Spawn agents on [Hetzner Cloud](https://www.hetzner.com/cloud/) servers. No `hcloud` CLI needed — uses the Hetzner REST API directly.

### Usage

#### Claude Code

```bash
bash <(curl -fsSL https://openrouter.ai/lab/spawn/hetzner/claude.sh)
```

### Non-Interactive Mode

```bash
HETZNER_SERVER_NAME=dev-mk1 \
HCLOUD_TOKEN=your-hetzner-api-token \
OPENROUTER_API_KEY=sk-or-v1-xxxxx \
 bash <(curl -fsSL https://openrouter.ai/lab/spawn/hetzner/claude.sh)
```

**Environment Variables:**
- `HETZNER_SERVER_NAME` - Name for the server (skips prompt)
- `HCLOUD_TOKEN` - Hetzner Cloud API token (skips prompt, saved to `~/.config/spawn/hetzner.json`)
- `OPENROUTER_API_KEY` - Skip OAuth and use this API key directly
- `HETZNER_SERVER_TYPE` - Server type (default: `cx22`)
- `HETZNER_LOCATION` - Datacenter location (default: `fsn1`)
