Anemone Browser — Managed Browser for OpenClaw Agents

Headful Chrome with anti-detection, VNC takeover, and multi-session isolation. Works on Mac, Linux, Docker — anywhere OpenClaw runs.

Setup

macOS

bash scripts/setup-mac.sh

Detects Chrome, configures OpenClaw browser profile. After setup:

openclaw browser start
# Agent's browser tool works automatically

Note: macOS setup does NOT include VNC/noVNC. The user is expected to access the Mac via their own remote desktop solution (e.g. macOS Screen Sharing, Tailscale, or physical access). VNC takeover with noVNC links is only available on Linux.

Linux / Docker

# Install deps (once)
bash scripts/setup.sh

# Start browser + VNC environment
bash scripts/start.sh [password] [novnc_port] [cdp_port] [resolution]

start.sh outputs the noVNC URL, password, and CDP port. Safe to re-run.

OpenClaw Config

Setup scripts configure this automatically. Manual reference:

macOS:

{
  "browser": {
    "enabled": true,
    "defaultProfile": "openclaw",
    "headless": false,
    "executablePath": "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
  }
}

Linux:

{
  "browser": {
    "enabled": true,
    "headless": false,
    "noSandbox": true,
    "executablePath": "/usr/bin/google-chrome-stable"
  }
}

Multi-Session Window Isolation

Multiple sessions share one Chrome (same cookies/logins) but each gets its own window.

Rules (MUST follow):

1. On session start — open your own tab, save the targetId:

   browser action=open targetUrl="https://example.com" profile=openclaw
   # Returns targetId — THIS IS YOURS, save it
   

2. ALL subsequent calls — always include your targetId:

   browser action=snapshot profile=openclaw targetId="<your-targetId>"
   browser action=navigate profile=openclaw targetId="<your-targetId>" targetUrl="..."
   browser action=act profile=openclaw targetId="<your-targetId>" ...
   

3. On session end — close your tab:

   browser action=close targetId="<your-targetId>"
   

4. NEVER operate without targetId — you'll land on another session's tab.

5. NEVER pick another session's tab from browser action=tabs.

Opening a new window (not tab) via CDP:

import json, asyncio, websockets, urllib.request

async def open_new_window(cdp_port, url):
    version = json.loads(urllib.request.urlopen(f"http://127.0.0.1:{cdp_port}/json/version").read())
    async with websockets.connect(version["webSocketDebuggerUrl"]) as ws:
        await ws.send(json.dumps({
            "id": 1, "method": "Target.createTarget",
            "params": {"url": url, "newWindow": True}
        }))
        resp = json.loads(await ws.recv())
        return resp["result"]["targetId"]
