For local development, run Sandbox Agent directly on your machine.

## With the CLI

```bash
# Install
curl -fsSL https://releases.rivet.dev/sandbox-agent/0.3.x/install.sh | sh

# Run
sandbox-agent server --no-token --host 127.0.0.1 --port 2468
```

Or with npm/Bun:

<Tabs>
  <Tab title="npx">
    ```bash
    npx @sandbox-agent/cli@0.3.x server --no-token --host 127.0.0.1 --port 2468
    ```
  </Tab>
  <Tab title="bunx">
    ```bash
    bunx @sandbox-agent/cli@0.3.x server --no-token --host 127.0.0.1 --port 2468
    ```
  </Tab>
</Tabs>

## With the TypeScript SDK

The SDK can spawn and manage the server as a subprocess using the `local` provider:

```typescript
import { SandboxAgent } from "sandbox-agent";
import { local } from "sandbox-agent/local";

const sdk = await SandboxAgent.start({
  sandbox: local(),
});

const session = await sdk.createSession({
  agent: "claude",
});

await session.prompt([
  { type: "text", text: "Summarize this repository." },
]);

await sdk.destroySandbox();
```

This starts the server on an available local port and connects automatically.

Pass options to customize the local provider:

```typescript
const sdk = await SandboxAgent.start({
  sandbox: local({
    port: 3000,
    log: "inherit",
    env: {
      ANTHROPIC_API_KEY: process.env.MY_ANTHROPIC_KEY,
    },
  }),
});
```
