Commands Reference

Navigation

webcli go <url>                    # Navigate to URL (auto-starts daemon)
webcli go <url> -w networkidle     # Wait for network to settle
webcli go <url> -t mytab           # Open in named tab
webcli back                        # Go back in history

webcli reload                      # Reload current page

Reading Page Content

webcli source                      # Get full visible text of the page
webcli links                       # List all links (text + href)
webcli forms                       # List all forms with their inputs
webcli html <selector>             # Get innerHTML of element
webcli attr <selector> <attribute> # Get element attribute value
webcli eval "<js>"                 # Execute JavaScript and return result
webcli title                       # Get the page title
webcli url                         # Get the current URL
webcli value <selector>            # Get input/textarea value
webcli count <selector>            # Count matching elements
webcli box <selector>              # Get bounding box (x, y, w, h)
webcli styles <selector> [props..] # Get computed CSS styles
webcli visible <selector>          # Check if element is visible
webcli enabled <selector>          # Check if element is enabled
webcli checked <selector>          # Check if checkbox is checked

Accessibility Snapshot (Recommended for AI agents)

webcli snapshot                    # Get accessibility tree with refs (@e1, @e2...)
webcli snapshot --all              # Include non-interactive elements
webcli snapshot --max-depth 5      # Limit tree depth

The snapshot assigns deterministic refs to interactive elements. Use these refs in other commands:

webcli snapshot                    # Get tree: [button @e1] "Submit", [textbox @e2] "Email"
webcli fill @e2 "user@example.com" # Fill using ref
webcli click @e1                   # Click using ref

Interaction

webcli click "<visible text>"      # Click element by visible text
webcli click @e1                   # Click element by snapshot ref
webcli clicksel "<css selector>"   # Click element by CSS selector
webcli dblclick "<text>"           # Double-click element by visible text
webcli hover "<selector>"          # Hover over an element
webcli fill "<selector>" "<value>" # Fill an input field (preferred for forms)
webcli type "<text>"               # Type with keyboard (for focused element)
webcli select "<selector>" "<val>" # Select dropdown option
webcli press Enter                 # Press keyboard key (Enter, Tab, Escape...)
webcli focus "<selector>"          # Focus an element
webcli check "<selector>"         # Check a checkbox
webcli uncheck "<selector>"       # Uncheck a checkbox
webcli drag "<from>" "<to>"        # Drag and drop between selectors
webcli upload "<selector>" <file>  # Upload a file to input[type=file]
webcli scroll down 500             # Scroll page (up/down/left/right, px)

Waiting

webcli wait "<selector>"           # Wait for CSS selector to be visible
webcli waitfor "<text>"            # Wait for text to appear on page
webcli sleep 2000                  # Sleep for N milliseconds

Screenshots & PDF

webcli quit -t mytab               # Close specific tab
webcli status                      # Show daemon info (PID, uptime, tabs)
webcli stop                        # Stop daemon and close browser

Global Options

All commands support:

• -t, --tab <name> — target a specific tab (default: "default")
• --json — output as structured JSON
• --timeout <ms> — command timeout (default: 30000)

Best Practices

Recommended workflow for AI agents

1. webcli go <url> to navigate
2. webcli snapshot to get accessibility tree with refs
3. Use refs for interaction: webcli click @e1, webcli fill @e2 "value"
4. webcli snapshot again to see updated state
5. webcli screenshot if user wants visual confirmation

Alternative workflow (text-based)

1. webcli go <url> to navigate
2. webcli source to read the page content
3. Use webcli click, webcli fill, webcli press to interact
4. webcli source again to see the result

Form filling

• Always use webcli fill for input fields — it properly sets React/Vue controlled inputs
• Use webcli click or webcli clicksel for buttons
• Use webcli press Enter to submit forms
• After submitting, use webcli sleep 1000 then webcli source to check the result

Multi-tab browsing

webcli go https://site-a.com -t research
webcli go https://site-b.com -t reference
webcli source -t research          # Read from specific tab
webcli source -t reference

Error recovery

• If a command times out, try webcli sleep 2000 then retry
• If an element is not found, use webcli source to check what's on the page
• If the daemon seems stuck, use webcli stop then retry the command
• Use webcli wait "<selector>" before interacting with dynamically loaded content

Important Notes

• Always read the page with webcli source or webcli snapshot before trying to interact
• Prefer webcli snapshot + refs for the most reliable element targeting
• Prefer webcli fill over webcli type for form inputs
• Prefer webcli click (by text) over webcli clicksel (by selector) when possible
• Use webcli sleep between rapid interactions to let pages update
• The daemon persists between commands — no need to re-navigate unless the page changes
