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

# Run Playwright automation
kernel browsers playwright execute <session_id> 'await page.goto("https://example.com")'
