OpenSandbox 开源：在自有基础设施上运行 AI 智能体沙箱

Run AI agents in sandboxes on your own infrastructure.

OpenSandbox gives AI applications isolated environments to execute code, run commands, manage files, and operate browsers or desktops. Start locally with Docker and deploy on Kubernetes through a unified sandbox API.

Features

Getting Started

Requirements:

• Docker (required for local execution)
• Python 3.10+ (required for examples and local runtime)

Install and Configure the Sandbox Server

uvx opensandbox-server init-config ~/.sandbox.toml --example docker

uvx opensandbox-server

# Show help
# uvx opensandbox-server -h

Create a Sandbox and Execute Commands/Scripts

Install the Sandbox SDK

uv pip install opensandbox

Create a sandbox from an alpine image and execute commands and scripts.

import asyncio

from opensandbox import Sandbox
from opensandbox.models import WriteEntry

async def main() -> None:
    # 1. Create a sandbox from the alpine image
    sandbox = await Sandbox.create("alpine")

    try:
        # 2. Execute a shell command
        execution = await sandbox.commands.run("echo 'Hello OpenSandbox!'")
        print(execution.logs.stdout[0].text)

        # 3. Write a script file
        await sandbox.files.write_files([
            WriteEntry(
                path="/tmp/hello.sh",
                data="echo \"Hello $1\"\necho '2 + 2 =' $((2 + 2))",
                mode=755,
            )
        ])

        # 4. Read the file back
        content = await sandbox.files.read_file("/tmp/hello.sh")
        print(f"Content: {content}")

        # 5. Execute the script
        execution = await sandbox.commands.run("sh /tmp/hello.sh OpenSandbox")
        for log in execution.logs.stdout:
            print(log.text)

    finally:
        # 6. Cleanup the sandbox
        await sandbox.destroy()

if __name__ == "__main__":
    asyncio.run(main())

Examples

SDKs

Pick your language:

Python

pip install opensandbox

Java/Kotlin (Gradle Kotlin DSL)

dependencies {
    implementation("com.alibaba.opensandbox:sandbox:{latest_version}")
}

Java/Kotlin (Maven)

<dependency>
    <groupId>com.alibaba.opensandbox</groupId>
    <artifactId>sandbox</artifactId>
    <version>{latest_version}</version>
</dependency>

JavaScript/TypeScript

npm install @alibaba-group/opensandbox

C#/.NET

dotnet add package Alibaba.OpenSandbox

Go

go get github.com/alibaba/OpenSandbox/sdks/sandbox/go

CLI

OpenSandbox also provides osb, a terminal CLI for the common sandbox workflow: create sandboxes, run commands, move files, inspect diagnostics, and manage runtime egress policy.

Install:

pip install opensandbox-cli
# or
uv tool install opensandbox-cli

Quick start:

osb config init
osb config set connection.domain localhost:8080
osb config set connection.protocol http
osb config set connection.api_key <your-api-key>
osb sandbox create --image python:3.12 --timeout 30m -o json
osb command run <sandbox-id> -o raw -- python -c "print(1 + 1)"

See the CLI README for the full command reference.

MCP

The OpenSandbox MCP server exposes sandbox creation, command execution, and text file operations to MCP-capable clients such as Claude Code and Cursor.

Install and run:

pip install opensandbox-mcp
opensandbox-mcp --domain localhost:8080 --protocol http

Minimal stdio config:

{
  "mcpServers": {
    "opensandbox": {
      "command": "opensandbox-mcp",
      "args": ["--domain", "localhost:8080", "--protocol", "http"]
    }
  }
}

See the MCP README for client-specific setup.

Official Container Images

OpenSandbox release images are published under the same component name in three official registries:

• Docker Hub: docker.io/opensandbox/<component>
• GitHub Container Registry: ghcr.io/opensandbox-group/opensandbox/<component>
• Alibaba Cloud Container Registry: sandbox-registry.cn-zhangjiakou.cr.aliyuncs.com/opensandbox/<component>

Tagged release images are signed keylessly with Cosign and include provenance attestations. Pin production images by digest and follow the release verification guide to verify the image against the OpenSandbox GitHub Actions identity before deployment.
