C Browser

Browser Automation

agent-browser (Vercel)

Navigate and interact with web pages using structured snapshots:

# Open a URL
agent-browser open "https://example.com"

# Get interactive element snapshot (shows clickable refs)
agent-browser snapshot -i

# Click an element by ref
agent-browser click @e2

# Fill a form field
agent-browser fill @e5 "search query"

# Take annotated screenshot
agent-browser screenshot --annotate

# Type text
agent-browser type "hello world"

# Press keys
agent-browser press Enter

playwright-cli (Microsoft)

Token-efficient browser automation designed for AI agents:

# Install browser (first time)
playwright-cli install-browser

# Navigate to URL
playwright-cli navigate "https://example.com"

# Get page snapshot
playwright-cli snapshot

Guidelines

• Use agent-browser for AI-driven web interaction (snapshot-ref pattern)
• Use playwright-cli for structured automation and testing flows
• Always check snapshots before clicking — element refs change between pages
• For login flows, navigate step by step and verify each page loads
• Respect robots.txt and rate limits when scraping
