MasterHttpRelayVPN Proxy

Skill by ara.so — Daily 2026 Skills collection.

MasterHttpRelayVPN is a domain-fronted HTTP/SOCKS5 proxy that tunnels traffic through Google Apps Script. It disguises requests as Google traffic to evade DPI/firewalls, performs local MITM TLS interception to re-encrypt traffic, and requires only a free Google account — no VPS needed.

Traffic flow:

Browser → Local Proxy (127.0.0.1:8085) → Google IP (front_domain) → Apps Script Relay → Target Website

Installation

git clone https://github.com/masterking32/MasterHttpRelayVPN.git
cd MasterHttpRelayVPN
pip install -r requirements.txt

Behind a firewall (PyPI mirror):

pip install -r requirements.txt -i https://mirror-pypi.runflare.com/simple/ --trusted-host mirror-pypi.runflare.com

Quick start scripts (handles venv + deps automatically):

# Linux/macOS
chmod +x start.sh && ./start.sh

# Windows
start.bat

Step 1: Deploy the Google Apps Script Relay

1. Go to https://script.google.com/ and create a New project
2. Delete default code, paste the contents of apps_script/Code.gs
3. Set a strong password on this line: const AUTH_KEY = "your-secret-password-here";
4. Click Deploy → New deployment → Web app

- Execute as: Me - Who has access: Anyone

1. Copy the Deployment ID (long random string)

Step 2: Configure

Option A — Interactive wizard (recommended)

python setup.py

Prompts for Deployment ID, generates a random auth_key, writes config.json.

Option B — Manual config

cp config.example.json config.json

Edit config.json:

{
  "mode": "apps_script",
  "google_ip": "216.239.38.120",
  "front_domain": "www.google.com",
  "script_id": "AKfycb...",
  "auth_key": "your-secret-password-here",
  "listen_host": "127.0.0.1",
  "listen_port": 8085,
  "socks5_enabled": true,
  "socks5_port": 1080,
  "log_level": "INFO",
  "verify_ssl": true
}

auth_key in config.json must match AUTH_KEY in Code.gs.

Step 3: Run

python3 main.py

Install CA certificate (run once, or re-run anytime):

python main.py --install-cert

  ]
}

CA Certificate Installation (Required for HTTPS)

The proxy performs MITM TLS interception. A local CA is generated at ca/ca.crt on first run. Install it once per machine/browser.

Linux (Ubuntu/Debian)

sudo cp ca/ca.crt /usr/local/share/ca-certificates/masterhttp-relay.crt
sudo update-ca-certificates

macOS

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ca/ca.crt

Windows (PowerShell as Admin)

certutil -addstore -f "ROOT" ca\ca.crt

Firefox (all platforms)

Settings → Privacy & Security → Certificates → View Certificates → Authorities → Import → select ca/ca.crt → check "Trust this CA to identify websites"

⚠️ Never share the ca/ folder. Delete it to regenerate a fresh CA.

Browser Proxy Configuration

HTTP Proxy: 127.0.0.1:8085 SOCKS5 Proxy: 127.0.0.1:1080

Firefox

Settings → General → Network Settings → Manual proxy configuration:

• HTTP Proxy: 127.0.0.1, Port: 8085
• Check: "Also use this proxy for HTTPS"

Chrome/Edge (Windows system proxy)

Settings → Network → Proxy → Manual proxy setup → 127.0.0.1:8085

Using curl for testing

curl -x http://127.0.0.1:8085 https://example.com
# or SOCKS5
curl --socks5 127.0.0.1:1080 https://example.com

Using requests in Python

import requests

proxies = {
    "http": "http://127.0.0.1:8085",
    "https": "http://127.0.0.1:8085",
}
response = requests.get("https://example.com", proxies=proxies)
print(response.status_code)

LAN Sharing Setup

Allow other devices on your network to use the proxy:

{
  "lan_sharing": true,
  "listen_host": "0.0.0.0",
  "listen_port": 8085
}

On startup, the proxy logs your LAN IP addresses. Configure other devices to use <YOUR_LAN_IP>:8085.

Load Balancing with Multiple Relays

Deploy multiple Google Apps Script projects and list all Deployment IDs:

{
  "script_ids": [
    "AKfycbFIRST_DEPLOYMENT_ID",
    "AKfycbSECOND_DEPLOYMENT_ID",
    "AKfycbTHIRD_DEPLOYMENT_ID"
  ],
  "auth_key": "same-password-in-all-scripts"
}

All Apps Script deployments must have the same AUTH_KEY value.

Common Patterns

Blocking ads/trackers

{
  "block_hosts": [
    ".doubleclick.net",
    ".googlesyndication.com",
    ".googleadservices.com",
    "ads.example.com"
  ]
}

Bypassing local/LAN resources (no MITM)

{
  "bypass_hosts": [
    "localhost",
    "127.0.0.1",
    ".local",
    ".lan",
    ".home.arpa",
    "192.168.1.0/24"
  ]
}

Running with debug logging

# In config.json
{ "log_level": "DEBUG" }

# Or temporarily
python3 main.py

Scripted config generation

import json
import secrets

config = {
    "mode": "apps_script",
    "google_ip": "216.239.38.120",
    "front_domain": "www.google.com",
    "script_id": "PASTE_DEPLOYMENT_ID_HERE",
    "auth_key": secrets.token_urlsafe(32),
    "listen_host": "127.0.0.1",
    "listen_port": 8085,
    "socks5_enabled": True,
    "socks5_port": 1080,
    "log_level": "INFO",
    "verify_ssl": True
}

with open("config.json", "w") as f:
    json.dump(config, f, indent=2)

print(f"Generated auth_key: {config['auth_key']}")
print("Remember to set this same value as AUTH_KEY in Code.gs")

Troubleshooting

"Security warning" on every website

→ CA certificate not installed. Run python main.py --install-cert or follow the manual install steps above.

Connection refused on port 8085

→ Check listen_host and listen_port in config.json. Make sure python3 main.py is running.

"403 Forbidden" from relay

→ auth_key in config.json does not match AUTH_KEY in deployed Code.gs. Redeploy the script after fixing.

Google Apps Script quota exceeded

→ Free tier has daily quotas. Add more script_ids in config.json for load balancing across multiple deployments.

verify_ssl errors

{ "verify_ssl": false }

Use only for testing; not recommended for production.

Regenerate CA certificate

rm -rf ca/
python3 main.py  # generates new ca/ca.crt on startup
# Then reinstall the certificate in OS/browser

Can't install Python packages (behind firewall)

pip install -r requirements.txt \
  -i https://mirror-pypi.runflare.com/simple/ \
  --trusted-host mirror-pypi.runflare.com

Test the proxy is working

# Should return your external IP routed through Google
curl -x http://127.0.0.1:8085 https://api.ipify.org
