Browser Automation with pnpx agent-browser

Quick start

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

Core workflow

1. Navigate: pnpx agent-browser open <url>
2. Snapshot: pnpx 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

Commands

Navigation

Copypnpx agent-browser open <url>      # Navigate to URL
pnpx agent-browser back            # Go back
pnpx agent-browser forward         # Go forward  
pnpx agent-browser reload          # Reload page
pnpx agent-browser close           # Close browser

Snapshot (page analysis)

Copypnpx agent-browser snapshot        # Full accessibility tree
pnpx agent-browser snapshot -i     # Interactive elements only (recommended)
pnpx agent-browser snapshot -c     # Compact output
pnpx agent-browser snapshot -d 3   # Limit depth to 3

Interactions (use @refs from snapshot)

Copypnpx agent-browser click @e1           # Click
pnpx agent-browser dblclick @e1        # Double-click
pnpx agent-browser fill @e2 "text"     # Clear and type
pnpx agent-browser type @e2 "text"     # Type without clearing
pnpx agent-browser press Enter         # Press key
pnpx agent-browser press Control+a     # Key combination
pnpx agent-browser hover @e1           # Hover
pnpx agent-browser check @e1           # Check checkbox
pnpx agent-browser uncheck @e1         # Uncheck checkbox
pnpx agent-browser select @e1 "value"  # Select dropdown
pnpx agent-browser scroll down 500     # Scroll page
pnpx agent-browser scrollintoview @e1  # Scroll element into view

Get information

Copypnpx agent-browser get text @e1        # Get element text
pnpx agent-browser get value @e1       # Get input value
pnpx agent-browser get title           # Get page title
pnpx agent-browser get url             # Get current URL

Screenshots

Copypnpx agent-browser screenshot          # Screenshot to stdout
pnpx agent-browser screenshot path.png # Save to file
pnpx agent-browser screenshot --full   # Full page

Wait

Copypnpx agent-browser wait @e1                     # Wait for element
pnpx agent-browser wait 2000                    # Wait milliseconds
pnpx agent-browser wait --text "Success"        # Wait for text
pnpx agent-browser wait --load networkidle      # Wait for network idle

Semantic locators (alternative to refs)

Copypnpx agent-browser find role button click --name "Submit"
pnpx agent-browser find text "Sign In" click
pnpx agent-browser find label "Email" fill "user@test.com"

Example: Form submission

Copypnpx agent-browser open https://example.com/form
pnpx agent-browser snapshot -i
# Output shows: textbox "Email" [ref=e1], textbox "Password" [ref=e2], button "Submit" [ref=e3]

pnpx agent-browser fill @e1 "user@example.com"
pnpx agent-browser fill @e2 "password123"
pnpx agent-browser click @e3
pnpx agent-browser wait --load networkidle
pnpx agent-browser snapshot -i  # Check result

Example: Authentication with saved state

Copy# Login once
pnpx agent-browser open https://app.example.com/login
pnpx agent-browser snapshot -i
pnpx agent-browser fill @e1 "username"
pnpx agent-browser fill @e2 "password"
pnpx agent-browser click @e3
pnpx agent-browser wait --url "**/dashboard"
pnpx agent-browser state save auth.json

# Later sessions: load saved state
pnpx agent-browser state load auth.json
pnpx agent-browser open https://app.example.com/dashboard

Sessions (parallel browsers)

Copypnpx agent-browser --session test1 open site-a.com
pnpx agent-browser --session test2 open site-b.com
pnpx agent-browser session list

JSON output (for parsing)

Add --json for machine-readable output:

Copypnpx agent-browser snapshot -i --json
pnpx agent-browser get text @e1 --json

Debugging

Copypnpx agent-browser open example.com --headed  # Show browser window
pnpx agent-browser console                    # View console messages
pnpx agent-browser errors                     # View page errors
