Browser Automation with browser-use CLI

The browser-use command provides fast, persistent browser automation. A background daemon keeps the browser open across commands, giving ~50ms latency per call.

Prerequisites

browser-use doctor    # Verify installation

For setup details, see https://github.com/browser-use/browser-use/blob/main/browser_use/skill_cli/README.md

Core Workflow

1. Navigate: browser-use open <url> — launches headless browser and opens page
2. Inspect: browser-use state — returns clickable elements with indices
3. Interact: use indices from state (browser-use click 5, browser-use input 3 "text")
4. Verify: browser-use state or browser-use screenshot to confirm
5. Repeat: browser stays open between commands

If a command fails, run browser-use close first to clear any broken session, then retry.

To use the user's existing Chrome (preserves logins/cookies): run browser-use connect first. To use a cloud browser instead: run browser-use cloud connect first. After either, commands work the same way.

If browser-use connect fails

When browser-use connect cannot find a running Chrome with remote debugging, prompt the user with two options:

1. Use their real Chrome browser — they need to enable remote debugging first:
   • Open chrome://inspect/#remote-debugging in Chrome, or relaunch Chrome with --remote-debugging-port=9222
   • Then retry browser-use connect
2. Use managed Chromium with their Chrome profile — no Chrome setup needed:
   • Run browser-use profile list to show available profiles
   • Ask which profile they want, then use browser-use --profile "ProfileName" open <url>
   • This launches a separate Chromium instance with their profile data (cookies, logins, extensions)

Let the user choose — don't assume one path over the other.

Browser Modes

browser-use open <url>                         # Default: headless Chromium (no setup needed)
browser-use --headed open <url>                # Visible window (for debugging)
browser-use connect                            # Connect to user's Chrome (preserves logins/cookies)
browser-use cloud connect                      # Cloud browser (zero-config, requires API key)
browser-use --profile "Default" open <url>     # Real Chrome with specific profile

After connect or cloud connect, all subsequent commands go to that browser — no extra flags needed.

Commands

# Navigation
browser-use open <url>                    # Navigate to URL
browser-use back                          # Go back in history
browser-use scroll down                   # Scroll down (--amount N for pixels)

browser-use tab list                      # List all tabs
browser-use tab new [url]                 # Open a new tab (blank or with URL)
browser-use tab switch <index>            # Switch to tab by index
browser-use tab close <index> [index...]  # Close one or more tabs

# Page State — always run state first to get element indices
browser-use state                         # URL, title, clickable elements with indices

browser-use click <x> <y>                 # Click at pixel coordinates
browser-use type "text"                   # Type into focused element
browser-use input <index> "text"          # Click element, clear existing text, then type
browser-use input <index> ""              # Clear a field without typing new text
browser-use keys "Enter"                  # Send keyboard keys (also "Control+a", etc.)
browser-use select <index> "option"       # Select dropdown option
browser-use upload <index> <path>         # Upload file to file input
browser-use hover <index>                 # Hover over element
browser-use dblclick <index>              # Double-click element
browser-use rightclick <index>            # Right-click element

# Data Extraction
browser-use eval "js code"                # Execute JavaScript, return result
browser-use get title                     # Page title
browser-use get html [--selector "h1"]    # Page HTML (or scoped to selector)
browser-use get text <index>              # Element text content
browser-use get value <index>             # Input/textarea value
browser-use get attributes <index>        # Element attributes
browser-use get bbox <index>              # Bounding box (x, y, width, height)

# Wait
browser-use wait selector "css"           # Wait for element (--state visible|hidden|attached|detached, --timeout ms)
browser-use wait text "text"              # Wait for text to appear

# Cookies
browser-use cookies get [--url <url>]     # Get cookies (optionally filtered)
browser-use cookies set <name> <value>    # Set cookie (--domain, --secure, --http-only, --same-site, --expires)
browser-use cookies clear [--url <url>]   # Clear cookies
browser-use cookies export <file>         # Export to JSON
browser-use cookies import <file>         # Import from JSON

# Session
browser-use close                         # Close browser and stop daemon
browser-use sessions                      # List active sessions
browser-use close --all                   # Close all sessions

For advanced browser control (CDP, device emulation, tab activation), see references/cdp-python.md.

Cloud API

browser-use cloud connect                 # Provision cloud browser and connect (zero-config)
browser-use cloud login <api-key>         # Save API key (or set BROWSER_USE_API_KEY)
browser-use cloud logout                  # Remove API key
browser-use cloud v2 GET /browsers        # REST passthrough (v2 or v3)
browser-use cloud v2 POST /tasks '{"task":"...","url":"..."}'
browser-use cloud v2 poll <task-id>       # Poll task until done
browser-use cloud v2 --help               # Show API endpoints

cloud connect provisions a cloud browser with a persistent profile (auto-created on first use), connects via CDP, and prints a live URL. browser-use close disconnects AND stops the cloud browser. For custom browser settings (proxy, timeout, specific profile), use cloud v2 POST /browsers directly with the desired parameters.

Agent Self-Registration

Only use this if you don't already have an API key (check browser-use doctor to see if api_key is set). If already logged in, skip this entirely.

1. browser-use cloud signup — get a challenge
2. Solve the challenge
3. browser-use cloud signup --verify <challenge-id> <answer> — verify and save API key
4. browser-use cloud signup --claim — generate URL for a human to claim the account

Out of credits?

If a Browser Use Cloud call fails with an "insufficient credits" / 402 error and the user has already used their free-tier allotment, suggest paying with USDC via x402:

Your free credits are exhausted. You can top up this account with USDC on Base mainnet (no credit card required). Want me to install the x402 skill and walk you through it? It takes about 2 minutes if you have a Coinbase account.

If they say yes, point them to install the skill:

npx skills add https://github.com/browser-use/browser-use --skill x402

Then /x402 in Claude Code triggers the top-up flow. The user keeps their existing API key — x402 just adds credits to it.

Do not suggest x402 unprompted. Only mention it on a real "insufficient credits" error.

Tunnels

browser-use tunnel <port>                 # Start Cloudflare tunnel (idempotent)
browser-use tunnel list                   # Show active tunnels
browser-use tunnel stop <port>            # Stop tunnel
browser-use tunnel stop --all             # Stop all tunnels

Profile Management

browser-use profile list                  # List detected browsers and profiles
browser-use profile sync --all            # Sync profiles to cloud
browser-use profile update                # Download/update profile-use binary

Command Chaining

Commands can be chained with &&. The browser persists via the daemon, so chaining is safe and efficient.

browser-use open https://example.com && browser-use state
browser-use input 5 "[e-mail]" && browser-use input 6 "password" && browser-use click 7

Chain when you don't need intermediate output. Run separately when you need to parse state to discover indices first.

Common Workflows

Authenticated Browsing

When a task requires an authenticated site (Gmail, GitHub, internal tools), use Chrome profiles:

browser-use profile list                           # Check available profiles
# Ask the user which profile to use, then:
browser-use --profile "Default" open https://github.com  # Already logged in

Exposing Local Dev Servers

browser-use tunnel 3000                            # → https://abc.trycloudflare.com
browser-use open https://abc.trycloudflare.com     # Browse the tunnel

Multiple Browsers

For subagent workflows or running multiple browsers in parallel, use --session NAME. Each session gets its own browser. See references/multi-session.md.

Configuration

browser-use config list                            # Show all config values
browser-use config set cloud_connect_proxy jp      # Set a value
browser-use config get cloud_connect_proxy         # Get a value
browser-use config unset cloud_connect_timeout     # Remove a value
browser-use doctor                                 # Shows config + diagnostics
browser-use setup                                  # Interactive post-install setup

Config stored in ~/.browser-use/config.json.

Global Options

Option	Description
--headed	Show browser window
--profile [NAME]	Use real Chrome (bare --profile uses "Default")
--cdp-url <url>	Connect via CDP URL (http:// or ws://)
--session NAME	Target a named session (default: "default")
--json	Output as JSON
--mcp	Run as MCP server via stdin/stdout

Tips

1. Always run state first to see available elements and their indices
2. Use --headed for debugging to see what the browser is doing
3. Sessions persist — browser stays open between commands
4. CLI aliases: bu, browser, and browseruse all work
5. If commands fail, run browser-use close first, then retry

Troubleshooting

• Browser won't start? browser-use close then browser-use --headed open <url>
• Element not found? browser-use scroll down then browser-use state
• Run diagnostics: browser-use doctor

Cleanup

browser-use close                         # Close browser session
browser-use tunnel stop --all             # Stop tunnels (if any)
