Surf Browser Automation

Control Chrome browser via CLI or Unix socket.

CLI Quick Reference

surf --help                    # Full help
surf <group>                   # Group help (tab, scroll, page, wait, dialog, emulate, form, perf, ai)
surf --help-full               # All commands
surf --find <term>             # Search tools
surf --help-topic <topic>      # Topic guide (refs, semantic, frames, devices, windows)

Core Workflow

# 1. Navigate to page
surf navigate "https://example.com"

# 2. Read page to get element refs
surf page.read

# 3. Click by ref or coordinates
surf click --ref "e1"
surf click --x 100 --y 200

# 4. Type text
surf type --text "hello"

# 5. Screenshot
surf screenshot --output /tmp/shot.png

AI Assistants (No API Keys)

Query AI models using your browser's logged-in session. Must be logged into the respective service in Chrome.

ChatGPT

surf chatgpt "explain this code"
surf chatgpt "summarize" --with-page              # Include current page context
surf chatgpt "review" --model gpt-4o              # Specify model
surf chatgpt "analyze" --file document.pdf        # With file attachment

Gemini

surf gemini "explain quantum computing"
surf gemini "summarize" --with-page               # Include page context
surf gemini "analyze" --file data.csv             # Attach file
surf gemini "a robot surfing" --generate-image /tmp/robot.png
surf gemini "add sunglasses" --edit-image photo.jpg --output out.jpg
surf gemini "summarize" --youtube "https://youtube.com/..."
surf gemini "hello" --model gemini-2.5-flash      # Models: gemini-3-pro (default), gemini-2.5-pro, gemini-2.5-flash
surf gemini "wide banner" --generate-image /tmp/banner.png --aspect-ratio 16:9

Perplexity

surf perplexity "what is quantum computing"
surf perplexity "explain this page" --with-page   # Include page context
surf perplexity "deep dive" --mode research       # Research mode (Pro)
surf perplexity "latest news" --model sonar       # Model selection (Pro)

Grok (via x.com - requires X.com login in Chrome)

surf grok "what are the latest AI trends on X"    # Search X posts
surf grok "analyze @username recent activity"     # Profile analysis  
surf grok "summarize this page" --with-page       # Include page context
surf grok "find viral AI posts" --deep-search     # DeepSearch mode
surf grok "quick question" --model fast           # Models: auto, fast, expert, thinking (default)

Grok Validation & Troubleshooting:

# Validate Grok UI and check available models (no query sent)
surf grok --validate

# If models changed, save discovered models to surf.json config
surf grok --validate --save-models

AI Tool Troubleshooting

When AI queries fail, check these common issues:

  1. Not logged in: The error "login required" means you need to log into the service in Chrome
  2. Model selection failed: The UI may have changed. Run surf grok --validate to check
  3. Response timeout: Thinking models (ChatGPT o1, Grok thinking) can take 45+ seconds
  4. Element not found: The service's UI changed. Check for surf-cli updates

Debugging workflow for agents:

# 1. Check if the service is accessible and UI is valid
surf grok --validate

# 2. If models mismatch, update the local settings
surf grok --validate --save-models

# 3. Retry with explicit model name from validation output
surf grok "query" --model <model-from-validation>

# 4. If still failing, try with longer timeout
surf grok "query" --timeout 600

Tab Management

surf tab.list
surf tab.new "https://google.com"
surf tab.switch 12345
surf tab.close 12345
surf tab.reload                # Reload current tab

# Named tabs (aliases)
surf tab.name myapp            # Name current tab
surf tab.switch myapp          # Switch by name
surf tab.named                 # List named tabs
surf tab.unname myapp          # Remove name

# Tab groups
surf tab.group                 # Create/add to tab group
surf tab.ungroup               # Remove from group
surf tab.groups                # List all tab groups

Window Management

surf window.list                              # List all windows
surf window.list --tabs                       # Include tab details
surf window.new                               # New window
surf window.new --url "https://example.com"   # New window with URL
surf window.new --incognito                   # New incognito window
surf window.new --unfocused                   # Don't focus new window
surf window.focus 12345                       # Focus window by ID
surf window.close 12345                       # Close window
surf window.resize --id 123 --width 1920 --height 1080
surf window.resize --id 123 --state maximized # States: normal, minimized, maximized, fullscreen

Window isolation for agents:

# Create isolated window for agent work
surf window.new "https://example.com"
# Returns window ID, use with subsequent commands:
surf --window-id 123 tab.list
surf --window-id 123 go "https://other.com"

Input Methods

# CDP method (real events) - default
surf type --text "hello"
surf click --x 100 --y 200

# JS method (DOM manipulation) - for contenteditable
surf type --text "hello" --selector "#input" --method js

# Keys
surf key Enter
surf key "cmd+a"
surf key.repeat --key Tab --count 5           # Repeat key presses

# Hover and drag
surf hover --ref e5
surf drag --from-x 100 --from-y 100 --to-x 200 --to-y 200

Page Inspection

surf page.read                 # Accessibility tree with refs + page text
surf page.read --no-text       # Interactive elements only (no text content)
surf page.read --ref e5        # Get specific element details
surf page.read --depth 3       # Limit tree depth
surf page.read --compact       # Minimal output for LLM efficiency
surf page.text                 # Plain text content only
surf page.state                # Modals, loading state, scroll info

Semantic Element Location

Find and act on elements by role, text, or label instead of refs:

# Find by ARIA role
surf locate.role button --name "Submit" --action click
surf locate.role textbox --name "Email" --action fill --value "test@example.com"
surf locate.role link --all                    # Return all matches

# Find by text content
surf locate.text "Sign In" --action click
surf locate.text "Accept" --exact --action click

# Find form field by label
surf locate.label "Username" --action fill --value "john"
surf locate.label "Password" --action fill --value "secret"

Actions: click, fill, hover, text (get text content)

Text Search

surf search "login"                    # Find text in page
surf search "Error" --case-sensitive   # Case-sensitive

Workflows

Execute multi-step browser automation as a single command with smart auto-waits.

Inline Workflows

# Pipe-separated commands
surf do 'go "https://example.com" | click e5 | screenshot'

# Multi-step login flow
surf do 'go "https://example.com/login" | type "user@example.com" --selector "#email" | type "pass" --selector "#password" | click --selector "button[type=submit]"'

# Validate without executing
surf do 'go "url" | click e5' --dry-run

Named Workflows

Save workflows as JSON files in ~/.surf/workflows/ (user) or ./.surf/workflows/ (project):

# List available workflows
surf workflow.list

# Show workflow details
surf workflow.info my-workflow

# Run by name with arguments
surf do my-workflow --email "user@example.com" --password "secret"

# Validate workflow file
surf workflow.validate workflow.json

Workflow JSON Format

{
  "name": "Login Flow",
  "description": "Automate login process",
  "args": {
    "email": { "required": true },
    "password": { "required": true },
    "url": { "default": "https://example.com/login" }
  },
  "steps": [
    { "tool": "navigate", "args": { "url": "%{url}" } },
    { "tool": "type", "args": { "text": "%{email}", "selector": "input[name=email]" } },
    { "tool": "type", "args": { "text": "%{password}", "selector": "input[name=password]" } },
    { "tool": "click", "args": { "selector": "button[type=submit]" } },
    { "tool": "screenshot", "args": {}, "as": "result" }
  ]
}

Loops and Step Outputs

{
  "steps": [
    // Capture step output for later use
    { "tool": "js", "args": { "code": "return [1,2,3]" }, "as": "items" },
    
    // Fixed iterations
    { "repeat": 5, "steps": [
      { "tool": "click", "args": { "ref": "e5" } }
    ]},
    
    // Iterate over array
    { "each": "%{items}", "as": "item", "steps": [
      { "tool": "js", "args": { "code": "console.log('%{item}')" } }
    ]},
    
    // Repeat until condition
    { "repeat": 20, "until": { "tool": "js", "args": { "code": "return done" } }, "steps": [...] }
  ]
}

Workflow Options

--file, -f <path>     # Load from JSON file
--dry-run             # Parse and validate without executing
--on-error stop|continue  # Error handling (default: stop)
--step-delay <ms>     # Delay between steps (default: 100, 0 to disable)
--no-auto-wait        # Disable automatic waits
--json                # Structured JSON output

Auto-waits: Commands automatically wait for completion:

  • Navigation (go, back, forward) → waits for page load
  • Clicks, key presses, form fills → waits for DOM stability
  • Tab switches → waits for tab to load

Why use do? Instead of 6-8 separate CLI calls with LLM orchestration between each, a workflow executes deterministically. Faster, cheaper, and more reliable.

Error Diagnostics

# Auto-capture screenshot + console on failure
surf wait.element ".missing" --auto-capture --timeout 2000
# Saves to /tmp/surf-error-*.png

Common Options

--tab-id <id>         # Target specific tab
--window-id <id>      # Target specific window
--json                # Raw JSON output  
--auto-capture        # Screenshot + console on error
--timeout <ms>        # Override default timeout

Tips

  1. First CDP operation is slow (~5-8s) - debugger attachment overhead, subsequent calls fast
  2. Use refs from page.read for reliable element targeting over CSS selectors
  3. JS method for contenteditable - Modern editors (ChatGPT, Claude, Notion) need --method js
  4. Named tabs for workflows - tab.name app then tab.switch app
  5. Auto-capture for debugging - --auto-capture saves diagnostics on failure
  6. AI tools use browser session - Must be logged into the service, no API keys needed
  7. Grok validation - Run surf grok --validate if queries fail to check UI changes
  8. Long timeouts for thinking models - ChatGPT o1, Grok thinking can take 60+ seconds
  9. Use surf do for multi-step tasks - Reduces token overhead and improves reliability
  10. Dry-run workflows first - surf do '...' --dry-run validates without executing
  11. Window isolation - Use window.new + --window-id to keep agent work separate from your browsing
  12. Semantic locators - locate.role, locate.text, locate.label for more robust element finding
  13. Frame context - Use frame.switch before interacting with iframe content

Socket API

For programmatic access:

echo '{"type":"tool_request","method":"execute_tool","params":{"tool":"tab.list","args":{}},"id":"1"}' | nc -U /tmp/surf.sock
