Browser Kit

Chromium browser via Playwright for browser automation.

Activation: Opt-in — only active if explicitly enabled in your config.

What's Included

• Chromium browser with all system dependencies
• playwright CLI for browser automation

Configuration

kits:
  browser: {}

Dependencies

Depends on the Node.js kit (Playwright is installed via npm).

Cache

The Playwright browser cache is persisted at /home/claude/.cache/ms-playwright in a named Docker volume. This avoids re-downloading Chromium on every container start.

Usage

# Take a screenshot
npx playwright screenshot https://example.com screenshot.png

# Run a Playwright script
npx playwright test

# Launch interactive codegen
npx playwright codegen https://example.com

Playwright can also be used programmatically from Node.js or Python scripts inside the container.
