camoufox-cli

Anti-detect browser CLI & Skills for AI agents, powered by Camoufox.

Highlights

• C++-level fingerprint spoofing via Camoufox (canvas, WebGL, audio, screen metrics, fonts)
• Persistent identities: stable fingerprint, OS, and locale across launches with --persistent
• Accessibility-tree snapshots with @ref element targeting
• Session isolation with cookie import/export
• Shell commands, no code generation

Works with

OpenClaw, Claude Code, Cursor, Codex, and any agent that can run shell commands.

Install

Tell your AI agent (e.g. OpenClaw):

Install this CLI and skills from https://github.com/Bin-Huang/camoufox-cli

Or install manually:

npm install -g camoufox-cli      # Requires Node.js 20.10+
camoufox-cli install              # Download browser

Or with pip:

pipx install camoufox-cli
camoufox-cli install              # Download browser

On Linux, install system dependencies with:

camoufox-cli install --with-deps

The browser is downloaded from GitHub releases. If the anonymous GitHub API rate limit is exhausted (common on shared server/CI IPs), the installer automatically falls back to scraping github.com release pages.

Quick Start

camoufox-cli open https://example.com    # Launch browser & navigate
camoufox-cli snapshot -i                  # Interactive elements only
# - link "More information..." [ref=e1]
camoufox-cli click @e1                    # Click by ref
camoufox-cli close                        # Done

Commands

Navigation

camoufox-cli open <url>                   # Navigate to URL (starts daemon if needed)
camoufox-cli back                         # Go back
camoufox-cli forward                      # Go forward
camoufox-cli reload                       # Reload page
camoufox-cli url                          # Print current URL
camoufox-cli title                        # Print page title
camoufox-cli close                        # Close your tab (browser exits when the last tab closes)

Snapshot

camoufox-cli snapshot                     # Full accessibility tree
camoufox-cli snapshot -i                  # Interactive elements only
camoufox-cli snapshot -s "css-selector"   # Scoped to CSS selector

Output format:

- heading "Example Domain" [level=1] [ref=e1]
- paragraph [ref=e2]
  - link "More information..." [ref=e3]

Interaction

camoufox-cli click @e1                    # Click element
camoufox-cli fill @e3 "search query"      # Clear + type into input
camoufox-cli type @e3 "append text"       # Type without clearing
camoufox-cli select @e5 "option text"     # Select dropdown option
camoufox-cli check @e6                    # Toggle checkbox
camoufox-cli hover @e2                    # Hover over element
camoufox-cli press Enter                  # Press keyboard key
camoufox-cli press "Control+a"            # Key combination

Data Extraction

camoufox-cli text @e1                     # Get text content of element
camoufox-cli text body                    # Get all page text
camoufox-cli eval "document.title"        # Execute JavaScript
camoufox-cli screenshot                   # Screenshot (JSON with base64)
camoufox-cli screenshot page.png          # Screenshot to file
camoufox-cli screenshot --full page.png   # Full page screenshot

Scroll & Wait

camoufox-cli scroll down                  # Scroll down 500px
camoufox-cli scroll up 1000               # Scroll up 1000px
camoufox-cli wait 2000                    # Wait milliseconds
camoufox-cli wait @e1                     # Wait for element to appear
camoufox-cli wait --url "*/dashboard"     # Wait for URL pattern

Tabs

camoufox-cli tabs                         # List open tabs (with owner names)
camoufox-cli switch 2                     # Switch to tab by index

Named tabs let concurrent agents share one browser — same fingerprint, same cookies/login state — while each keeps its own page, element refs, and history. Tabs share one browser process (commands from different tabs may queue behind a slow one); separate sessions run as independent processes in parallel:

camoufox-cli --tab inbox-scan-x4q open https://app.example.com/a
camoufox-cli --tab report-pull-9kf open https://app.example.com/b
camoufox-cli --tab inbox-scan-x4q snapshot -i   # refs are per tab
camoufox-cli --tab inbox-scan-x4q close         # frees only this tab; browser exits when the last tab closes

Tab names must be unique per agent (nothing enforces this): use a task slug plus a short shell-generated random suffix (e.g. price-scan-$(openssl rand -hex 2)), chosen once and reused.

Sessions

Each named session is a separate browser process with its own randomly-generated fingerprint and its own cookies. Use sessions for isolated identities, named tabs (above) for cheap parallelism under one identity. For real multi-account isolation, combine sessions with a per-session proxy (config file) and --persistent — see Persistent Identity below:

camoufox-cli sessions                     # List active sessions
camoufox-cli --session work open <url>    # Use named session
camoufox-cli close --all                  # Force-close all sessions

Cookies

camoufox-cli cookies                      # Dump cookies as JSON
camoufox-cli cookies import file.json     # Import cookies
camoufox-cli cookies export file.json     # Export cookies

Flags

--session <name>       Named session (default: "default")
--tab <name>           Named tab within the session's shared browser: same fingerprint and
                       cookies/login, independent page/refs/history (default: "default")
--headed               Show browser window (default: headless)
--timeout <seconds>    Daemon idle timeout (default: 1800)
--json                 Output as JSON
--persistent [path]    Persistent identity (see below); default path: ~/.camoufox-cli/profiles/<session>
--proxy <url>          Proxy server (http:// or https://; auth: http://user:pass@host:port)
--no-geoip             Disable automatic GeoIP spoofing (auto-enabled with --proxy)
--locale <tag>         Force browser locale (e.g. "en-US" or "en-US,zh-CN")
--version              Print version and exit

Config File

Tired of repeating the same flags on every call? Put defaults in ~/.camoufox-cli/config.json (override the path with $CAMOUFOX_CLI_CONFIG):

{
  "default": {
    "persistent": true,
    "timeout": 3600,
    "proxy": "http://user:pass@host:8080"
  },
  "sessions": {
    "<your-session-name>": {
      "proxy": "socks5://127.0.0.1:1080",
      "locale": "zh-CN"
    }
  }
}

• default applies to every session.
• sessions is optional. You never pre-register sessions — the name is just whatever you pass to --session. A sessions.<name> block only kicks in when you happen to run --session <name>, layering its keys on top of default; any other session (or no --session at all) just uses default. Above, camoufox-cli --session <your-session-name> open <url> swaps in that block's proxy + locale, while every other session keeps the default proxy.
• Command-line flags always win over the file, which in turn wins over built-in defaults.
• Settable keys: proxy, locale, geoip, persistent (true / false / path string), headed, timeout, json. session is command-line only (it selects which block to apply), and per-command options like --full or -i are never read from config.
• A broken config never blocks a command — it's ignored with a warning on stderr.
• Config is read when a session's daemon first launches. If one is already running for that session, run camoufox-cli --session <name> close first for changes to take effect.

Persistent Identity

Without --persistent, every launch gets a fresh random fingerprint. With --persistent, a camoufox-cli.json file is written next to the browser's user data. Fingerprint, OS, and canvas/font seeds are generated on the first launch and frozen afterwards; locale and proxy-derived timezone/geolocation are also saved but track whatever you pass on the command line. Every subsequent launch with the same path reloads the identity, so sites see the same device on every visit.

# First launch: generates + stores identity
camoufox-cli --persistent ~/.camoufox-cli/profiles/alice open https://example.com

# Every subsequent launch: same fingerprint, same cookies, same device
camoufox-cli --persistent ~/.camoufox-cli/profiles/alice open https://example.com

Frozen — generated on the first launch, permanent until the directory is deleted:

• Fingerprint (UA, canvas, WebGL, fonts, navigator properties)
• OS (defaults to host OS)
• Canvas/font noise seeds

Persisted — stored in the file, refreshed whenever you pass the flag:

• --locale: sets the stored locale; pass it again to change it, omit it to keep the stored value.
• Timezone / geolocation: re-derived from the current proxy's IP whenever --proxy is active (and --no-geoip isn't set), then written back. Without a proxy, the last stored values stay in effect.

Per-launch — never stored; pass on every launch for it to apply:

• --proxy: proxies rotate or expire; re-specify each launch to avoid silently running through a stale one.
• --no-geoip: follows the current --proxy.

Multiple identities in parallel. Each persistent path is a distinct identity. Combine with --session for concurrent daemons:

camoufox-cli --session a --persistent ~/.camoufox-cli/profiles/alice open https://...
camoufox-cli --session b --persistent ~/.camoufox-cli/profiles/bob   open https://...

Resetting an identity. Just delete the directory (rm -rf ~/.camoufox-cli/profiles/alice). The next launch generates a fresh one.

Architecture

CLI (camoufox-cli)  ──Unix socket──▶  Daemon (Python)  ──Playwright──▶  Camoufox (Firefox)

The CLI sends JSON commands to a long-running daemon process via Unix socket. The daemon manages the Camoufox browser instance and maintains the ref registry between commands. The daemon auto-starts on the first command and auto-stops after 30 minutes of inactivity.
