Agent Browser

Browser Automation with agent-browser

Quick start

agent-browser open <url>        # Navigate to page
agent-browser snapshot -i       # Get interactive elements with refs
agent-browser click @e1         # Click element by ref
agent-browser fill @e2 "text"   # Fill input by ref
agent-browser close             # Close browser

Core workflow

1. Navigate: agent-browser open <url>
2. Snapshot: agent-browser snapshot -i (returns elements with refs like @e1, @e2)
3. Interact using refs from the snapshot
4. Re-snapshot after navigation or significant DOM changes
5. Always close: agent-browser close

Commands

Navigation

agent-browser open <url>      # Navigate to URL
agent-browser close           # Close browser (ALWAYS do this)

Snapshot (page analysis)

agent-browser snapshot        # Full accessibility tree
agent-browser snapshot -i     # Interactive elements only (recommended)

Interactions (use @refs from snapshot)

agent-browser click @e1           # Click
agent-browser fill @e2 "text"     # Clear and type
agent-browser type @e2 "text"     # Type without clearing
agent-browser press Enter         # Press key
agent-browser scroll down 500     # Scroll page

Get information

agent-browser get text @e1        # Get element text
agent-browser get title           # Get page title
agent-browser get url             # Get current URL

Wait

agent-browser wait @e1                     # Wait for element
agent-browser wait 2000                    # Wait milliseconds
agent-browser wait --load networkidle      # Wait for network idle

Example: Form submission (request-website)

# Open Actionbook request page
agent-browser open "https://actionbook.dev/request-website"

# Get form elements
agent-browser snapshot -i
# Output shows: textbox "Site URL" [ref=e1], textbox "Email" [ref=e2], textbox "Use Case" [ref=e3], button "Submit" [ref=e4]

# Fill form
agent-browser fill @e1 "https://example.com/products"
agent-browser fill @e2 "user@example.com"
agent-browser fill @e3 "Scraping product catalog"

# Submit
