Kernel CLI

The Kernel CLI provides command-line access to Kernel's cloud browser platform for browser automation, serverless app deployment, and infrastructure management.

Installation

• Homebrew: brew install kernel/tap/kernel (>=v0.13.4)
• npm: npm install -g @onkernel/cli (>=v0.13.4)

Authentication

• Preferred: Set KERNEL_API_KEY environment variable
• Fallback: Run kernel login for interactive OAuth

Quick Start

# Authenticate
export KERNEL_API_KEY=your_api_key

# Create a browser session
kernel browsers create -o json

# Run Playwright automation (use `return` to get a value back)
kernel browsers playwright execute <session_id> '
  await page.goto("https://example.com");
  return await page.evaluate(() => document.title);
'

# Take a screenshot
kernel browsers computer screenshot <session_id> --to screenshot.png

# Cleanup
kernel browsers delete <session_id>
