Flow:

1. User pastes a config link (vless://..., vmess://..., trojan://...) in the popup
2. Extension parses the config and sends it to the native host via Chrome Native Messaging
3. Native host generates Xray-compatible JSON config and launches Xray core as a local SOCKS5 proxy
4. Extension sets Chrome proxy settings (chrome.proxy API) to point to 127.0.0.1:SOCKS5_PORT
5. All browser traffic is now routed through the V2Ray server
6. Real-time traffic statistics are displayed in the popup

Note: This extension requires a native messaging host component to run the Xray core binary. Chrome extensions cannot implement raw TCP/VLESS protocol directly due to browser sandbox restrictions. See Installation for setup instructions.

Installation

Prerequisites

• Google Chrome, Microsoft Edge, Brave, or any Chromium-based browser
• Go 1.21+ (to build the native host — or use the pre-built binary from the Releases page)
• A V2Ray/VLESS/VMess/Trojan server config link

Step 1: Install the Extension

Option A: Load Unpacked (Developer Mode)

1. Download this repository:

   git clone https://github.com/coldhell7/Chrome-extention-Vpnforall.git
   cd Chrome-extention-Vpnforall

2. Open chrome://extensions/ in your browser
3. Enable Developer mode (toggle in top-right corner)
4. Click Load unpacked and select the extension/ folder

Option B: Install CRX (Release)

1. Download vpnforall.crx from the Releases page
2. Open chrome://extensions/
3. Enable Developer mode
4. Drag and drop vpnforall.crx onto the page

Step 2: Install the Native Messaging Host

Why? Chrome extensions cannot directly implement V2Ray/VLESS protocol. The native host runs the Xray core, which does the actual proxy work.

On macOS / Linux

# Make the installer executable
chmod +x native-host/install.sh

# Run the installer
./native-host/install.sh

The installer will:

1. Build the Go native host binary
2. Download Xray core from GitHub releases
3. Register the native messaging host with Chrome
4. Ask for your Extension ID — copy it from chrome://extensions/

On Windows (PowerShell)

# Run PowerShell as Administrator
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

# Run the installer
.\native-host\install.ps1

The installer will:

1. Build the Go native host binary
2. Download Xray core from GitHub releases
3. Register the native messaging host in the registry
4. Ask for your Extension ID — copy it from chrome://extensions/

Step 3: Get Your Extension ID

1. Go to chrome://extensions/
2. Find VPN for All in the list
3. Copy its ID (e.g., abcdefghijklmnopabcdefghijklmnop)
4. Enter this ID when prompted by the installer script

Step 4: Reload & Connect

1. After installation, go back to chrome://extensions/
2. Click the Refresh icon on the VPN for All card
3. Click the extension icon in your toolbar
4. Paste your config link (e.g., vless://...) and click Connect

Usage

Connecting to a Server

1. Click the VPN for All icon in your Chrome toolbar
2. Paste your config link into the text area:

   vless://your-uuid@your-server.com:443?security=tls&sni=your-server.com&type=tcp&encryption=none#My%20Server
   

3. Click Connect
4. Chrome traffic is now routed through your V2Ray server

Saving Profiles

1. Paste a config link
2. Click + Add to Profiles
3. Switch to the Profiles tab to see your saved servers
4. Click Connect on any saved profile to quickly switch

Multi-Profile Setup

Each Chrome profile can use a different proxy server on a different port:

Chrome Profile	Port	Server
Default	10801	🇯🇵 Japan
Work	10803	🇺🇸 US
Personal	10805	🇸🇬 Singapore

Important: Use different ports for different Chrome profiles. Each port corresponds to a separate Xray process.

Traffic Stats

The Stats tab shows:

• Upload — Total data sent + current upload speed
• Download — Total data received + current download speed
• Connection — Current status, connection time, active profile

Building from Source

Prerequisites

• Go 1.21+
• Node.js 18+
• OpenSSL (for CRX signing)

Build Everything

# Clone the repo
git clone https://github.com/coldhell7/Chrome-extention-Vpnforall.git
cd Chrome-extention-Vpnforall

# Run the build script
chmod +x build.sh
./build.sh

The build script:

1. Compiles native host binaries for all platforms (Linux/macOS/Windows × amd64/arm64)
2. Creates dist/vpnforall.crx (packed Chrome extension)
3. Creates dist/vpnforall.zip (unpacked extension archive)
4. Copies installer scripts to dist/

FAQ / Troubleshooting

"Native host not found" error

• Make sure you ran the installer script (install.sh or install.ps1)
• Verify the native messaging manifest is in the correct location:
  • macOS: ~/Library/Application Support/Google/Chrome/NativeMessagingHosts/
  • Linux: ~/.config/google-chrome/NativeMessagingHosts/
  • Windows: %LOCALAPPDATA%\Google\Chrome\User Data\NativeMessagingHosts\
• Check that the Extension ID in the manifest matches your extension's ID

Connection fails after clicking Connect

• Check your server config is valid (paste it in another V2Ray client to test)
• Verify the Xray binary downloaded correctly: check ~/.vpnforall/xray
• Look at the extension logs: chrome://extensions/ → VPN for All → Service Worker → Console
• Check if port 10801 is already in use: lsof -i :10801

"Port already in use" error

• Different Chrome profiles must use different ports (10801, 10803, 10805, etc.)
• Kill stale Xray processes:
  • macOS/Linux: pkill xray
  • Windows: Task Manager → find xray.exe → End Task

Traffic stats show 0 B/s

• Traffic monitor updates every second
• Make sure there is active browser traffic
• Refresh the popup and check again

Which browsers are supported?

• Google Chrome
• Microsoft Edge
• Mozilla Firefox (requires Firefox-specific native messaging paths)
• Brave
• Opera
• Any Chromium-based browser

Why do I need a native host?

Chrome extensions run in a sandboxed JavaScript environment. They cannot:

• Create raw TCP/UDP sockets
• Execute system processes
• Implement the VLESS/VMess protocol directly

The native messaging host bridges this gap by running Xray core as a system process and communicating with the extension via stdin/stdout.
