Browser Automation with browser-use CLI

The browser-use command provides fast, persistent browser automation. It maintains browser sessions across commands, enabling complex multi-step workflows.

Prerequisites

Before using this skill, browser-use must be installed and configured. Run diagnostics to verify:

browser-use doctor

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

Core Workflow

Navigate: browser-use open <url> - Opens URL (starts browser if needed)
Inspect: browser-use state - Returns clickable elements with indices
Interact: Use indices from state to interact (browser-use click 5, browser-use input 3 "text")
Verify: browser-use state or browser-use screenshot to confirm actions
Repeat: Browser stays open between commands

Browser Modes

browser-use --browser chromium open <url>      # Default: headless Chromium
browser-use --browser chromium --headed open <url>  # Visible Chromium window
browser-use --browser real open <url>          # Real Chrome (no profile = fresh)
browser-use --browser real --profile "Default" open <url>  # Real Chrome with your login sessions
browser-use --browser remote open <url>        # Cloud browser

chromium: Fast, isolated, headless by default
real: Uses a real Chrome binary. Without --profile, uses a persistent but empty CLI profile at ~/.config/browseruse/profiles/cli/. With --profile "ProfileName", copies your actual Chrome profile (cookies, logins, extensions)
remote: Cloud-hosted browser with proxy support

browser-use cookies clear --url <url>     # Clear cookies for specific URL
browser-use cookies export <file>         # Export all cookies to JSON file
browser-use cookies export <file> --url <url>  # Export cookies for specific URL
browser-use cookies import <file>         # Import cookies from JSON file

Wait Conditions

browser-use wait selector "h1"            # Wait for element to be visible
browser-use wait selector ".loading" --state hidden  # Wait for element to disappear
browser-use wait selector "#btn" --state attached    # Wait for element in DOM
browser-use wait text "Success"           # Wait for text to appear
browser-use wait selector "h1" --timeout 5000  # Custom timeout in ms

Python Execution

browser-use python "x = 42"               # Set variable
browser-use python "print(x)"             # Access variable (outputs: 42)
browser-use python "print(browser.url)"   # Access browser object
browser-use python --vars                 # Show defined variables
browser-use python --reset                # Clear Python namespace
browser-use python --file script.py       # Execute Python file

The Python session maintains state across commands. The browser object provides:

browser.url, browser.title, browser.html — page info
browser.goto(url), browser.back() — navigation
browser.click(index), browser.type(text), browser.input(index, text), browser.keys(keys) — interactions
browser.screenshot(path), browser.scroll(direction, amount) — visual
browser.wait(seconds), browser.extract(query) — utilities

Common Workflows

Exposing Local Dev Servers

Use when you have a local dev server and need a cloud browser to reach it.

Core workflow: Start dev server → create tunnel → browse the tunnel URL remotely.

# 1. Start your dev server
npm run dev &  # localhost:3000

# 2. Expose it via Cloudflare tunnel
browser-use tunnel 3000
# → url: https://abc.trycloudflare.com

# 3. Now the cloud browser can reach your local server
browser-use --browser remote open https://abc.trycloudflare.com
browser-use state

Note: Tunnels are independent of browser sessions. They persist across browser-use close and can be managed separately. Cloudflared must be installed — run browser-use doctor to check.

Authenticated Browsing with Profiles

Use when a task requires browsing a site the user is already logged into (e.g. Gmail, GitHub, internal tools).

Core workflow: Check existing profiles → ask user which profile and browser mode → browse with that profile. Only sync cookies if no suitable profile exists.

Before browsing an authenticated site, the agent MUST:

Ask the user whether to use real (local Chrome) or remote (cloud) browser
List available profiles for that mode
Ask which profile to use
If no profile has the right cookies, offer to sync (see below)

Step 1: Check existing profiles

# Option A: Local Chrome profiles (--browser real)
browser-use -b real profile list
# → Default: Person 1 (user@gmail.com)
# → Profile 1: Work (work@company.com)

# Option B: Cloud profiles (--browser remote)
browser-use -b remote profile list
# → abc-123: "Chrome - Default (github.com)"
# → def-456: "Work profile"

Step 2: Browse with the chosen profile

# Real browser — uses local Chrome with existing login sessions
browser-use --browser real --profile "Default" open https://github.com

# Cloud browser — uses cloud profile with synced cookies
browser-use --browser remote --profile abc-123 open https://github.com

The user is already authenticated — no login needed.

Note: Cloud profile cookies can expire over time. If authentication fails, re-sync cookies from the local Chrome profile.

Step 3: Syncing cookies (only if needed)

If the user wants to use a cloud browser but no cloud profile has the right cookies, sync them from a local Chrome profile.

Before syncing, the agent MUST:

Ask which local Chrome profile to use
Ask which domain(s) to sync — do NOT default to syncing the full profile
Confirm before proceeding

Check what cookies a local profile has:

browser-use -b real profile cookies "Default"
# → youtube.com: 23
# → google.com: 18
# → github.com: 2

Domain-specific sync (recommended):

browser-use profile sync --from "Default" --domain github.com
# Creates new cloud profile: "Chrome - Default (github.com)"
# Only syncs github.com cookies

Full profile sync (use with caution):

browser-use profile sync --from "Default"
# Syncs ALL cookies — includes sensitive data, tracking cookies, every session token

Only use when the user explicitly needs their entire browser state.

Fine-grained control (advanced):

# Export cookies to file, manually edit, then import
browser-use --browser real --profile "Default" cookies export /tmp/cookies.json
browser-use --browser remote --profile <id> cookies import /tmp/cookies.json

Use the synced profile:

browser-use --browser remote --profile <id> open https://github.com

Running Subagents

Use cloud sessions to run autonomous browser agents in parallel.

Core workflow: Launch task(s) with run → poll with task status → collect results → clean up sessions.

Session = Agent: Each cloud session is a browser agent with its own state
Task = Work: Jobs given to an agent; an agent can run multiple tasks sequentially
Session lifecycle: Once stopped, a session cannot be revived — start a new one

Launching Tasks

# Single task (async by default — returns immediately)
browser-use -b remote run "Search for AI news and summarize top 3 articles"
# → task_id: task-abc, session_id: sess-123

# Parallel tasks — each gets its own session
browser-use -b remote run "Research competitor A pricing"
# → task_id: task-1, session_id: sess-a
browser-use -b remote run "Research competitor B pricing"
# → task_id: task-2, session_id: sess-b
browser-use -b remote run "Research competitor C pricing"
# → task_id: task-3, session_id: sess-c

# Sequential tasks in same session (reuses cookies, login state, etc.)
browser-use -b remote run "Log into example.com" --keep-alive
# → task_id: task-1, session_id: sess-123
browser-use task status task-1  # Wait for completion
browser-use -b remote run "Export settings" --session-id sess-123
# → task_id: task-2, session_id: sess-123 (same session)

Managing & Stopping

browser-use task list --status finished      # See completed tasks
browser-use task stop task-abc               # Stop a task (session may continue if --keep-alive)
browser-use session stop sess-123            # Stop an entire session (terminates its tasks)
browser-use session stop --all               # Stop all sessions

Monitoring

Task status is designed for token efficiency. Default output is minimal — only expand when needed:

Mode	Flag	Tokens	Use When
Default	(none)	Low	Polling progress
Compact	`-c`	Medium	Need full reasoning
Verbose	`-v`	High	Debugging actions

# For long tasks (50+ steps)
browser-use task status <id> -c --last 5   # Last 5 steps only
browser-use task status <id> -v --step 10  # Inspect specific step

Live view: browser-use session get <session-id> returns a live URL to watch the agent.

Detect stuck tasks: If cost/duration in task status stops increasing, the task is stuck — stop it and start a new agent.

Logs: browser-use task logs <task-id> — only available after task completes.

Global Options

Option	Description
`--session NAME`	Use named session (default: "default")
`--browser MODE`	Browser mode: chromium, real, remote
`--headed`	Show browser window (chromium mode)
`--profile NAME`	Browser profile (local name or cloud ID). Works with `open`, `session create`, etc. — does NOT work with `run` (use `--session-id` instead)
`--json`	Output as JSON
`--mcp`	Run as MCP server via stdin/stdout

Session behavior: All commands without --session use the same "default" session. The browser stays open and is reused across commands. Use --session NAME to run multiple browsers in parallel.

Tips

Always run browser-use state first to see available elements and their indices
Use --headed for debugging to see what the browser is doing
Sessions persist — the browser stays open between commands
Use --json for programmatic parsing
Python variables persist across browser-use python commands within a session
CLI aliases: bu, browser, and browseruse all work identically to browser-use

Troubleshooting

Run diagnostics first:

browser-use doctor

Browser won't start?

browser-use close --all               # Close all sessions
browser-use --headed open <url>       # Try with visible window

Element not found?

browser-use state                     # Check current elements
browser-use scroll down               # Element might be below fold
browser-use state                     # Check again

Session issues?

browser-use sessions                  # Check active sessions
browser-use close --all               # Clean slate
browser-use open <url>                # Fresh start

Session reuse fails after task stop: If you stop a task and try to reuse its session, the new task may get stuck at "created" status. Create a new session instead:

browser-use session create --profile <profile-id> --keep-alive
browser-use -b remote run "new task" --session-id <new-session-id>

Task stuck at "started": Check cost with task status — if not increasing, the task is stuck. View live URL with session get, then stop and start a new agent.

Sessions persist after tasks complete: Tasks finishing doesn't auto-stop sessions. Run browser-use session stop --all to clean up.

Cleanup

Always close the browser when done:

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