Multilogin

Multilogin X

Manage anti-detect browser profiles via the xcli CLI.

CRITICAL: Launcher must run FIRST

The mlx-launcher process MUST be running before ANY xcli command (except login) will work. If you skip this, you WILL get "connection refused" or "launcher not active" errors.

Installation

Version resolution

Both binaries have a /latest endpoint that returns the current version string:

https://ml000x-dev-dists.s3.eu-north-1.amazonaws.com/cli-mlx/latest       → e.g. "0.0.72"
https://ml000x-dev-dists.s3.eu-north-1.amazonaws.com/launcher-mlx/latest   → e.g. "1.75.0"

Download URLs follow the pattern:

https://ml000x-dev-dists.s3.eu-north-1.amazonaws.com/cli-mlx/{VERSION}/xcli_{PLATFORM}
https://ml000x-dev-dists.s3.eu-north-1.amazonaws.com/launcher-mlx/{VERSION}/launcher-{PLATFORM}

Environment Detection

Detect your environment before running commands:

# Am I in Docker?
if [ -f /.dockerenv ]; then
  echo "DOCKER"
else
  echo "BARE METAL"
fi

Both environments use the same xcli and mlx-launcher binaries — they must be in PATH.

Headless (VPS / Docker) — Step by Step

This is the primary mode. No display, no GUI. Profiles run headless.

Step 1: Start the launcher

mlx-launcher -port 45000 &
sleep 5

Verify:

xcli launcher-info

You MUST see a version number before proceeding. If error — wait and retry.

Step 2: Login

xcli login --username 'USER@EMAIL' --password 'PASSWORD'

Ask the user for credentials if not provided. Tokens last 24h, stored in `/.config/xcli/`.

Step 3: Launch quick profiles

Quick profiles are disposable — deleted automatically when stopped.

xcli profile-quick --browser-type mimic --os-type linux --automation puppeteer --headless

Launch 2 quick profiles:

xcli profile-quick --browser-type mimic --os-type linux --automation puppeteer --headless
xcli profile-quick --browser-type mimic --os-type linux --automation puppeteer --headless

Each returns a profile ID and a port for Puppeteer/Selenium automation.

Headless constraints

• Always use --headless — no display server available.
• Always use --os-type linux — must match the host OS.
• Always use --browser-type mimic — stealthfox is NOT available on Linux.
• Do NOT use profile-create for disposable sessions — use profile-quick.
• Do NOT run xcli commands in background with & (only mlx-launcher).

Desktop (macOS / Windows / Linux with GUI)

When running on a machine with a display (e.g. a Mac node), profiles can open visible browser windows.

Step 1: Start the launcher

mlx-launcher -port 45000 &
sleep 5
xcli launcher-info

Step 2: Login

xcli login --username 'USER@EMAIL' --password 'PASSWORD'

Step 3: Launch profiles (with GUI)

On macOS:

xcli profile-quick --browser-type mimic --os-type macos --automation puppeteer
xcli profile-quick --browser-type stealthfox --os-type macos --automation puppeteer

On Windows:

xcli profile-quick --browser-type mimic --os-type windows --automation puppeteer
xcli profile-quick --browser-type stealthfox --os-type windows --automation puppeteer

Note: No --headless flag — browser windows will be visible.

Desktop constraints

• --os-type must match the actual OS (macos, windows, or linux).
• Both mimic (Chromium) and stealthfox (Firefox) are available on macOS and Windows.
• On Linux with GUI, only mimic is available.

GUI via OpenClaw Node (VPS + Mac hybrid)

The most elegant setup: VPS runs 24/7 headless, Mac node handles GUI tasks on demand.

Architecture

VPS (OpenClaw main agent, 24/7, headless)
  ↕ paired via gateway
Mac (OpenClaw Node, paired device)
  → runs Multilogin with visible browser windows
  → VPS delegates GUI tasks here

When to use the Node

Use the VPS for:

• Headless quick profiles (automation, scraping, batch tasks)
• All non-GUI work

Delegate to the Mac node when:

• User wants to SEE the browser (visual inspection, manual interaction)
• A task requires a real display (CAPTCHAs, visual verification)
• stealthfox is needed (not available on Linux)
• Debugging a profile visually

How to delegate to the Node

From the VPS main agent, use sessions_spawn to send a task to the Mac node:

{
  "tool": "sessions_spawn",
  "agentId": "node-mac",
  "message": "Start the Multilogin launcher and launch 2 quick profiles with GUI. Use: mlx-launcher -port 45000 & sleep 5 && xcli login --username 'USER' --password 'PASS' && xcli profile-quick --browser-type mimic --os-type macos --automation puppeteer && xcli profile-quick --browser-type stealthfox --os-type macos --automation puppeteer"
}

The node will:

1. Start the launcher locally on the Mac
2. Login with the provided credentials
3. Launch profiles with visible browser windows
4. Report back the profile IDs and ports

Setup requirements for the Node

The Mac node needs:

• xcli and mlx-launcher binaries for macOS in PATH (see Install on macOS above)
• Network access to Multilogin API (signin.multilogin.com)
• OpenClaw Node running and paired to the VPS gateway
