Proxy God — Rotating Proxy Chain Manager for Windows

Auto-fetches, validates and rotates multi-hop proxy chains with a live GUI, Windows kill-switch firewall, system proxy enforcement, and tray icon. Works on top of NordVPN (or any VPN) as the outer tunnel.

YOU → NordVPN (OS tunnel) → Hop 1 → Hop 2 → Hop 3 → Internet

---

Features

• Auto proxy pool — fetches from Proxifly CDN every 30 min, validates concurrently
• Multi-hop GOST chains — 2–8 hops, randomly picked from validated pool
• Obfuscation modes — Auto, HTTP-only, SOCKS5-only, Random Mix
• Manual chain builder — drag/reorder hops, pin your own IPs
• Fixed exit (last hop) — optional URL used only as the final hop; earlier hops still rotate randomly (ignored when a full manual chain is pinned)
• Exit IP verification — checks real exit IP every health cycle, rotates if it matches your real IP
• Windows system proxy — sets HKCU registry proxy so all WinINet apps use the chain
• Firewall kill-switch — netsh rules that block all outbound except GOST + NordVPN when running as Admin
• Tray icon — green/yellow/red circle, right-click menu
• Boot persistence — Task Scheduler logon task

Requirements

• Windows 10/11 x64
• Python 3.10+ (or use the pre-built .exe)
• NordVPN (recommended but optional — any VPN works)

---

Quick Start (from source)

git clone https://gitea.thetempleofdoom.com/drjones/proxy-god.git
cd proxy-god
pip install -r requirements.txt
python run.py

Run as Administrator for full kill-switch firewall enforcement.

Usage

1. Launch ProxyChainManager.exe (accept UAC prompt for Admin)
2. Configure settings in Settings tab if needed (defaults work fine)
3. Click ▶ Start — the app will:
   • Download GOST (one time, ~9 MB) and add Defender exclusion
   • Fetch proxy lists from Proxifly CDN
   • Validate them concurrently
   • Build a random N-hop chain
   • Verify the exit IP is different from your real IP
   • Set Windows system proxy
   • Engage firewall kill-switch (Admin only)
4. Close window → minimizes to tray (chain keeps running)
5. Click Quit or tray → Quit to fully stop

---

Chain Builder Tab

• Obfuscation mode — selects which protocols to include in chains
• Hop count slider — 1–8 total hops (top bar ± or slider)
• Fixed exit (last hop only) — optional field: your SOCKS/HTTP proxy is always the last hop before the internet; all earlier hops are still chosen at random from the validated pool. Leave empty for a fully automatic chain. Set hop count to 1 to use only your fixed exit (no pool). While Pin & use this chain is on, the full pinned list wins and fixed exit is ignored.
• Manual chain — enter proxies manually, reorder with ↑↓, enable "Use this chain" to pin it
• Paste current — copies the auto-selected chain into the editor
• Sources — add/remove proxy list URLs (JSON format from Proxifly)

Proxy Sources

Default sources use proxifly/free-proxy-list CDN:

• https://cdn.jsdelivr.net/gh/proxifly/free-proxy-list@main/proxies/protocols/http/data.json
• https://cdn.jsdelivr.net/gh/proxifly/free-proxy-list@main/proxies/protocols/socks5/data.json
• https://cdn.jsdelivr.net/gh/proxifly/free-proxy-list@main/proxies/protocols/https/data.json

You can add any URL returning a JSON array of {"proxy":"http://ip:port", ...} objects.

Notes

• Free public proxies are untrusted — do not send sensitive unencrypted data
• NordVPN (or any VPN) as the OS tunnel means the proxy operators only see the VPN exit IP, not your ISP IP
• Kill-switch requires Admin — UAC prompt appears on launch
• Works on cloned VMs — all listeners bind to 127.0.0.1, not the machine's LAN IP
