CubeSandbox

Project Overview

Cube Sandbox is a high-performance, out-of-the-box secure sandbox service built on RustVMM and KVM. It is compatible with the E2B SDK and can create a hardware-isolated, fully serviceable sandbox in under 60ms with less than 5MB memory overhead.

Key Features

• Instant startup: < 60ms sandbox creation
• Lightweight: < 5MB memory overhead
• Hardware isolation: Built on RustVMM and KVM
• Kubernetes deployment: K8s deploy support
• Snapshot & clone: CubeCoW Copy-on-Write snapshot engine

Target Audience

• AI agent developers and platform engineers
• Developers needing secure isolated environments
• Cloud-native application developers

Quick Start

1. Refer to the Quick Start guide
2. Deploy a cluster with Terraform
3. Create sandboxes via the E2B-compatible SDK
4. Start running AI agents

Core Advantages

• Instant startup (< 60ms)
• Minimal memory overhead (< 5MB)
• Hardware-level security isolation
• E2B SDK compatible

System Requirements

• OS: Linux (KVM support)
• Architectures: x86_64, arm64
• Additional Dependencies: KVM, Rust (for building)

Notes
