# Castari

**Deploy Claude agents with one command.**

Castari is the natural runtime for AI agents. We deploy your Claude agents in secure, auto-scaling sandboxes — so you go from prototype to production in minutes, not weeks.

<Tip>
  **Using Claude Code?** Type `/castari-deploy` and deploy your agent without leaving the editor. Install the plugin with `npx skills add castari/cli`. [Get started →](/guides/claude-code)
</Tip>

## How It Works

```bash theme={null}
# 1. Install
npm install -g @castari/cli

# 2. Login
cast login

# 3. Create an agent
cast init my-agent

# 4. Deploy
cd my-agent && cast deploy

# 5. Invoke
cast invoke my-agent "Hello!"
```

That's it. Your agent is now running in a secure sandbox, ready to scale.
