Playwright Example

Access web pages in headless mode using Playwright + Chromium in OpenSandbox to scrape title/body snippets.

Build the Playwright Sandbox Image

The Dockerfile in the example directory builds a sandbox image with Playwright and Chromium pre-installed:

cd examples/playwright
docker build -t opensandbox/playwright:latest .

This image includes:

• Playwright Python package
• Chromium browser binaries
• Node.js and npm (for Playwright MCP)
• Non-root user (playwright) for security

Start OpenSandbox server [local]

Pre-pull the Playwright image:

docker pull sandbox-registry.cn-zhangjiakou.cr.aliyuncs.com/opensandbox/playwright:latest

Start the local OpenSandbox server:

uv pip install opensandbox-server
opensandbox-server init-config ~/.sandbox.toml --example docker
opensandbox-server

Create and Access the Playwright Sandbox

# Install OpenSandbox package
uv pip install opensandbox

uv run python examples/playwright/main.py

The script launches Chromium in headless mode to access the target URL, prints title/body snippets, and saves a full-page screenshot to /home/playwright/screenshot.png inside the sandbox. It also downloads the screenshot to the local working directory as ./screenshot.png. Uses the prebuilt Playwright image by default.
