# Using OpenReward Sandboxes

> Use OpenReward native sandbox infrastructure with ORS environments

## Overview

[ORS](https://openrewardstandard.io) environments work with any sandbox provider - E2B, Daytona, Modal, or others. OpenReward also provides a native sandbox option that integrates directly with the platform's environment file storage.

## When to Use OpenReward Sandboxes

OpenReward sandboxes may be a good fit if you:

* **Already use OpenReward**: Same API key for environments and sandboxes
* **Use environment file storage**: Direct mounting of environment buckets

For specialised needs, external providers like E2B, Daytona, or Modal may offer better solutions.

## Features

* **Multiple machine sizes**: From `0.1:0.1` (minimal) to `4:16` (high-memory workloads)
* **Flexible configuration**: Custom container images, resources, and environment variables
* **Network isolation**: Optional network blocking for secure code execution
* **Storage mounting**: Access environment cloud storage with bucket mounting
* **Sidecar support**: Run additional services (Redis, PostgreSQL, etc.)
