# Introducing the Cua CLI: Manage Cloud Sandboxes from Your Terminal

If you've been using our Cloud Sandboxes, you've probably been managing them through the web dashboard - clicking through forms to create instances, copying credentials, manually starting and stopping sandboxes. It works, but it's not exactly built for power users like yourself.

Today we're launching the **Cua CLI**: a command-line interface that brings the full power of our Cloud Sandbox platform to your terminal. Create, manage, and connect to Linux, Windows, or macOS sandboxes in seconds—all from a single command.

## What You Can Do

The Cua CLI handles everything you need to work with Cloud Sandboxes:

**Authentication**

- Browser-based OAuth login with automatic credential storage
- Direct API key support for CI/CD pipelines
- Export credentials to `.env` files for SDK integration

**Sandbox Management**

- Create sandboxes with your choice of OS, size, and region
- List all your sandboxes with status and connection details
- Start, stop, restart, and delete sandboxes
- Open remote desktop (VNC) connections directly in your browser

**Two Command Styles**
The CLI supports both flat and grouped command structures—use whichever fits your workflow:

```bash
# Grouped style (explicit & clear)
cua sb ls
cua sb create --os linux --size small --region north-america
cua sb vnc my-sandbox

# Flat style (quick & concise)
cua ls
cua create --os linux --size small --region north-america
cua vnc my-sandbox
```

Both styles work identically. The CLI shows grouped commands in help by default, but all flat commands remain available for backwards compatibility.

## Installation

One command installs everything (includes Bun runtime + Cua CLI):

```bash
# macOS/Linux
curl -LsSf https://cua.ai/cli/install.sh | sh

# Windows
powershell -ExecutionPolicy ByPass -c "irm https://cua.ai/cli/install.ps1 | iex"
```

Or install via npm if you prefer:

```bash
npm install -g @trycua/cli
```

## Getting Started

Authenticate with your Cua account:

```bash
# Interactive browser login (recommended)
cua auth login

# Or provide your API key directly
cua auth login --api-key sk-your-api-key-here
```

Create a sandbox:

```bash
cua sb create --os linux --size small --region north-america
# Sandbox created and ready: my-sandbox-abc123
# Password: secure-password-here
# Host: my-sandbox-abc123.sandbox.cua.ai
```

List your sandboxes:

```bash
cua sb list
# NAME                 STATUS    HOST
# my-sandbox-abc123    running   my-sandbox-abc123.sandbox.cua.ai
# test-windows-456     stopped   test-windows-456.sandbox.cua.ai
```

Open a remote desktop:

```bash
cua sb vnc my-sandbox-abc123
# Opens your browser to the VNC interface with password pre-filled
```

## SDK Integration

Export your API key to a `.env` file for seamless SDK integration:

```bash
cd my-project
cua auth env
# Wrote /path/to/my-project/.env
```

Then use it with our Python or TypeScript SDKs:

```python
from computer import Computer

computer = Computer(
    os_type="linux",
    provider_type="cloud",
    name="my-sandbox-abc123",
    api_key="your-api-key"  # Or load from .env
)

await computer.run()
```

## Sandbox Sizes & Regions

Create sandboxes in the size and region that fits your needs:

**Sizes:**

- `small` - 2 cores, 8 GB RAM, 128 GB SSD
- `medium` - 4 cores, 16 GB RAM, 128 GB SSD
- `large` - 8 cores, 32 GB RAM, 256 GB SSD

**Regions:**

- `north-america`
- `europe`
- `asia-pacific`
- `south-america`

**OS Options:**

- `linux` - Ubuntu with XFCE desktop
- `windows` - Windows 11 with Edge and Python
- `macos` - macOS (preview access)

## Example Workflows

**Quick Testing Environment**

```bash
# Spin up a sandbox, test something, tear it down
cua sb create --os linux --size small --region north-america
# ... do your testing ...
cua sb delete my-sandbox-abc123
```

**Persistent Development Sandbox**

```bash
# Create a sandbox for long-term use
cua sb create --os linux --size medium --region north-america

# Stop it when not in use (data persists)
cua sb stop my-sandbox-abc123

# Start it again when needed
cua sb start my-sandbox-abc123
```

**CI/CD Integration**

```bash
# Provision sandboxes in your pipeline
export CUA_API_KEY="sk-your-api-key"
cua auth login --api-key "$CUA_API_KEY"
cua sb create --os linux --size large --region north-america

# Run your tests with the Cua Computer SDK
python run_tests.py

# Clean up
cua sb delete my-test-sandbox
```

## Command Aliases

We've added aliases for common commands to speed up your workflow:

```bash
# List aliases
cua list    # or: cua ls, cua ps, cua sb list

# VNC aliases
cua vnc     # or: cua open, cua sb vnc
```

## FAQs

<details>
<summary><strong>Can I use this in scripts and CI/CD?</strong></summary>

Yes. All commands support non-interactive mode with `--api-key` flags, and the CLI exits with proper status codes for scripting. The flat command style (`cua list`, `cua create`) is particularly useful for quick scripts.

</details>

<details>
<summary><strong>Where are my credentials stored?</strong></summary>

API keys are stored in `~/.cua/cli.sqlite` using a local SQLite database. They never leave your machine. Use `cua auth logout` to clear stored credentials.

</details>

<details>
<summary><strong>What happens to passwords in the output?</strong></summary>

Passwords are hidden by default in `cua list` for security. Use `cua list --show-passwords` to display them when needed.

</details>

<details>
<summary><strong>Can I manage sandboxes created through the web dashboard?</strong></summary>

Yes. The CLI and dashboard share the same API. Any sandbox you create in the dashboard will show up in `cua list`, and vice versa.

</details>

<details>
<summary><strong>How do I update the CLI?</strong></summary>

If you installed via script:

```bash
curl -LsSf https://cua.ai/cli/install.sh | sh
```

If you installed via npm:

```bash
npm install -g @trycua/cli@latest
```

</details>

## What's Next

We're actively iterating based on feedback. Planned features include:

- SSH key management for secure sandbox access
- Template-based sandbox creation
- Batch operations (start/stop multiple sandboxes)
- Custom sandbox configurations
- Snapshot management
