# OpenSandbox — Secure AI Agent Sandbox by Alibaba

> An open-source sandbox runtime by Alibaba for running AI agent code safely, providing fast startup, strong isolation, and extensible tool integration.

## Install

Save as a script file and run:

# OpenSandbox — Secure AI Agent Sandbox by Alibaba

## Quick Use
```bash
pip install opensandbox
opensandbox create --runtime python3.11
opensandbox exec "import os; print(os.listdir('/'))"
```

## Introduction
OpenSandbox is an open-source sandbox runtime by Alibaba designed for AI agents to execute code safely. It provides fast container startup, strong process isolation, and a pluggable tool system, making it suitable for production AI agent deployments that need to run untrusted code.

## What OpenSandbox Does
- Creates isolated execution environments for AI-generated code
- Provides sub-second container startup for responsive agent workflows
- Enforces resource limits on CPU, memory, disk, and network
- Supports Python, Node.js, and shell execution runtimes
- Integrates with Kubernetes for scalable deployment

## Architecture Overview
OpenSandbox uses lightweight container technology with a custom runtime that optimizes for fast cold starts. Each sandbox instance runs in an isolated namespace with its own filesystem, network stack, and process tree. A control plane manages sandbox lifecycle, resource quotas, and tool registration. The architecture supports both single-node and Kubernetes-based multi-node deployments.

## Self-Hosting & Configuration
- Install via pip or deploy as a Kubernetes operator
- Configure resource limits per sandbox via YAML policies
- Register custom tools and file mounts for agent access
- Set network policies to control outbound connectivity
- Monitor sandbox health via built-in Prometheus metrics

## Key Features
- Sub-second sandbox creation for low-latency agent responses
- Strong isolation with namespace and cgroup enforcement
- Pluggable runtime support for Python, Node.js, and shell
- Kubernetes-native operator for production scaling
- Built-in resource monitoring and quota enforcement

## FAQ
**Q: Is OpenSandbox production-ready?**
A: Yes. It is developed by Alibaba and designed for production AI agent deployments.

**Q: Can agents access the internet from sandboxes?**
A: Configurable. Network policies can allow or deny outbound access per sandbox.

**Q: How fast is sandbox creation?**
A: Sub-second cold starts using pre-warmed container pools and optimized image layers.

**Q: What runtimes are supported?**
A: Python 3.x, Node.js, and shell environments. Custom runtimes can be added via container images.
