Browser Automation with agent-browser

Quick start

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

Commands

Navigation

bash
bun x agent-browser open <url>      # Navigate to URL
bun x agent-browser back            # Go back
bun x agent-browser forward         # Go forward
bun x agent-browser reload          # Reload page
bun x agent-browser close           # Close browser

Snapshot (page analysis)

bash
bun x agent-browser snapshot            # Full accessibility tree
bun x agent-browser snapshot -i         # Interactive elements only (recommended)
bun x agent-browser snapshot -c         # Compact output
bun x agent-browser snapshot -d 3       # Limit depth to 3
bun x agent-browser snapshot -s "#main" # Scope to CSS selector

Interactions (use @refs from snapshot)

bash
bun x agent-browser click @e1           # Click
bun x agent-browser dblclick @e1        # Double-click
bun x agent-browser focus @e1           # Focus element
bun x agent-browser fill @e2 "text"     # Clear and type
bun x agent-browser type @e2 "text"     # Type without clearing
bun x agent-browser press Enter         # Press key
bun x agent-browser press Control+a     # Key combination
bun x agent-browser keydown Shift       # Hold key down
bun x agent-browser keyup Shift         # Release key
bun x agent-browser hover @e1           # Hover
bun x agent-browser check @e1           # Check checkbox
bun x agent-browser uncheck @e1         # Uncheck checkbox

bash
bun x agent-browser get text @e1        # Get element text
bun x agent-browser get html @e1        # Get innerHTML
bun x agent-browser get value @e1       # Get input value
bun x agent-browser get attr @e1 href   # Get attribute
bun x agent-browser get title           # Get page title
bun x agent-browser get url             # Get current URL
bun x agent-browser get count ".item"   # Count matching elements

bun x agent-browser is visible @e1      # Check if visible
bun x agent-browser is enabled @e1      # Check if enabled
bun x agent-browser is checked @e1      # Check if checked

Screenshots & PDF

bash

Video recording

bash
