AgentBay:All in One Sandbox

Last Updated:Feb 12, 2026

This topic describes how to build a full-featured All-in-One Sandbox environment using the AgentBay Linux Computer Use image.

Background

The All-in-One Sandbox is a highly integrated cloud development and execution environment. It combines Linux desktop automation, a browser, and a code execution engine. This provides a standardized, out-of-the-box runtime environment for automated tasks (especially AI agents), cloud development, and secure code execution.

This solution uses a unified containerization architecture to eliminate environmental differences, file transfer complexities, and interaction barriers found in legacy, fragmented toolchains. This approach enables end-to-end integration and seamless operations.

Solution overview

This solution uses a Linux sandbox session as an all-in-one sandbox. It uses the linux_latest image to perform the following:

  • session.computer for desktop automation.

  • session.browser for browser automation.

  • session.code for code execution (such as Python).

This environment is particularly useful when you need to perform user interface interactions and script execution (or quickly retrieve web content) in a single session without switching images.

Core features

  • Environment consistency: Encapsulates the browser, terminal, file system, and developer tools in a unified environment to eliminate inconsistencies.

  • Out-of-the-box: Comes pre-installed with common languages, frameworks, and build tools to save time on environment setup.

  • Security isolation: Uses the VPC and an independent container environment to ensure secure task execution and data control.

  • Auto scaling: Supports creating and destroying environments in seconds with on-demand resource configuration for cost optimization.

  • Multimodal integration: Integrates Browser Use, Code Space, and Computer Use capabilities within a single Linux image for seamless toolchain collaboration.

Preparations

Implementation examples

The following examples use the same linux_latest session type and demonstrate:

  • Running code with session.code.run_code().

  • Using the browser agent API with session.browser.

Example 1: Run code in linux_latest (similar to Code space)

import os

from agentbay import AgentBay, CreateSessionParams


def main() -> None:
    api_key = os.getenv("AGENTBAY_API_KEY")
    if not api_key:
        raise RuntimeError("AGENTBAY_API_KEY environment variable not set")

    ab = AgentBay(api_key=api_key)
    create_result = ab.create(CreateSessionParams(image_id="linux_latest"))
    if not create_result.success:
        raise RuntimeError(create_result.error_message)

    session = create_result.session
    try:
        code = """
print("RUN_CODE_OK")
print(6 * 7)
""".strip()
        result = session.code.run_code(code, "python")
        if not result.success:
            raise RuntimeError(result.error_message)
        print(result.result)
    finally:
        session.delete()


if __name__ == "__main__":
    main()
    

Example 2: Use the browser API in linux_latest

This example uses the browser agent API (no local Playwright required) to navigate to a page and take a screenshot.

import os

from agentbay import AgentBay, BrowserOption, CreateSessionParams


def main() -> None:
    api_key = os.getenv("AGENTBAY_API_KEY")
    if not api_key:
        raise RuntimeError("AGENTBAY_API_KEY environment variable not set")

    ab = AgentBay(api_key=api_key)
    create_result = ab.create(CreateSessionParams(image_id="linux_latest"))
    if not create_result.success:
        raise RuntimeError(create_result.error_message)

    session = create_result.session
    try:
        if not session.browser.initialize(BrowserOption()):
            raise RuntimeError("Failed to initialize browser")

        session.browser.agent.navigate("https://example.com")
        data = session.browser.agent.screenshot(full_page=False)
        print("Screenshot data prefix:", data[:30])
    finally:
        session.delete()


if __name__ == "__main__":
    main()
