browser-use CLI Skill

What This Skill Covers

Use this skill any time you need to automate a browser from the command line using browser-use. This includes navigating pages, clicking/typing/filling forms, taking screenshots, running JavaScript, managing tabs, handling cookies, driving cloud browsers, and exposing local servers via tunnels.

Installation

Prerequisites

One-line Install (Recommended)

# macOS / Linux
curl -fsSL https://browser-use.com/cli/install.sh | bash

# Windows (PowerShell)
& "C:\Program Files\Git\bin\bash.exe" -c 'curl -fsSL https://browser-use.com/cli/install.sh | bash'

Manual Install

uv pip install browser-use
browser-use install   # downloads Chromium
browser-use doctor    # validates setup

Post-Install Health Check

browser-use doctor   # prints diagnostics + config
browser-use setup    # optional interactive wizard

Core Mental Model

The workflow is always:

1. Open a page → browser-use open <url>
2. Inspect the page → browser-use state (returns numbered element indices)
3. Interact using those indices → browser-use click 3, browser-use input 1 "text"
4. Repeat — the daemon keeps the browser alive between commands (~50ms latency)

A background daemon process starts automatically on first command and stays alive until you browser-use close.

Browser Modes

# Default: headless Chromium (invisible)
browser-use open https://example.com

# Visible window
browser-use --headed open https://example.com

# Use your real Chrome (preserves logins, cookies, extensions)
browser-use connect

# Use a specific Chrome profile
browser-use --profile "Default" open https://gmail.com

# Zero-config cloud browser (requires API key)
browser-use cloud connect

# Connect to existing browser via CDP
browser-use --cdp-url http://localhost:9222 open https://example.com
browser-use --cdp-url ws://localhost:9222/devtools/browser/... state

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

All Commands

Navigation

browser-use open <url>               # Navigate to URL

browser-use eval "window.scrollTo(0, document.body.scrollHeight)"

Python (Persistent Session)

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

Session Management

Each --session gets its own daemon, socket, and browser instance.

# Default session (implicit)
browser-use open https://example.com
browser-use state

# Named sessions
browser-use --session work open https://example.com
browser-use --session personal open https://gmail.com
browser-use --session work state    # targets work browser

# List all active sessions
browser-use sessions

# Close a specific session
browser-use --session work close

# Close all sessions
browser-use close --all

# Via environment variable
BROWSER_USE_SESSION=work browser-use state

Cloud API

Auth

browser-use cloud login sk-abc123...    # Save API key
browser-use cloud logout                # Remove API key
# Or: export BROWSER_USE_API_KEY=sk-abc123...

Cloud Browser

browser-use cloud connect              # Provision cloud browser and connect
browser-use state                      # Works normally after connect
browser-use close                      # Disconnect AND stop cloud browser
browser-use cloud close                # Also stops cloud browser

REST Passthrough

browser-use cloud v2 GET /browsers
browser-use cloud v2 POST /tasks '{"task":"Search for AI news","url":"https://google.com"}'
browser-use cloud v2 poll <task-id>    # Poll until task completes
browser-use cloud v3 POST /path '{"key":"value"}'
browser-use cloud v2 --help            # Show all v2 API endpoints
browser-use cloud v3 --help            # Show all v3 API endpoints

Tunnels (Expose Local Server to Cloud Browser)

browser-use tunnel 3000                # Expose localhost:3000 → public HTTPS URL
browser-use tunnel list                # List active tunnels
browser-use tunnel stop 3000           # Stop tunnel for port
browser-use tunnel stop --all          # Stop all tunnels

# Typical flow for testing local app with a cloud browser:
npm run dev &
browser-use tunnel 3000                # → https://abc.trycloudflare.com
browser-use cloud connect
browser-use open https://abc.trycloudflare.com

Profile Management (Sync Chrome Cookies to Cloud)

browser-use profile                    # Interactive sync wizard
browser-use profile list               # List detected browsers + profiles
browser-use profile sync --all         # Sync all profiles to cloud
browser-use profile sync --browser "Google Chrome" --profile "Default"
browser-use profile auth --apikey <key>
browser-use profile inspect --browser "Google Chrome" --profile "Default"
browser-use profile update             # Update the profile-use binary

Global Options

Configuration

Common Recipes

Fill and Submit a Form

browser-use open https://example.com/contact
browser-use state
# Output: [0] input "Name", [1] input "Email", [2] button "Submit"
browser-use input 0 "John Doe"
browser-use input 1 "john@example.com"
browser-use click 2
browser-use wait text "Thank you"

Scrape Data with JavaScript

browser-use open https://news.ycombinator.com
browser-use eval "Array.from(document.querySelectorAll('.titleline a')).slice(0,5).map(a => a.textContent)"

Multi-step Python Automation

browser-use open https://example.com
browser-use python "
for i in range(5):
    browser.scroll('down')
    browser.wait(0.5)
browser.screenshot('scrolled.png')
"

Login with Saved Chrome Profile

browser-use --profile "Default" open https://gmail.com
browser-use state
# Gmail inbox loads already logged in

Run Two Browsers in Parallel

browser-use --session a open https://site-a.com
browser-use --session b open https://site-b.com
browser-use --session a state
browser-use --session b state
browser-use close --all

Test Local App via Cloud Browser

npm run dev &
browser-use tunnel 3000
# Copy the printed public URL, e.g. https://xyz.trycloudflare.com
browser-use cloud connect
browser-use open https://xyz.trycloudflare.com
browser-use screenshot check.png

Windows Troubleshooting

ARM64 Windows — install x64 Python for emulation:

winget install Python.Python.3.11 --architecture x64

Multiple Python versions — pin the version:

$env:PY_PYTHON=3.11

PATH not updated — restart terminal, or run via Git Bash:

& "C:\Program Files\Git\bin\bash.exe" -c 'browser-use --help'

Daemon won't start — kill stale processes:

wmic process where "name='python.exe' and commandline like '%browser%use%'" get processid
taskkill /PID <pid> /F

Stale venv — nuke and reinstall:

wmic process where "name='python.exe' and commandline like '%browser%use%'" call terminate
Remove-Item -Recurse -Force "$env:USERPROFILE\.browser-use-env"
# Re-run the installer
