A process-level transparent proxy for Windows. It injects a DLL and hooks the Winsock API to route traffic from selected applications and their child processes through an HTTP proxy — without changing routing tables or installing a virtual network adapter.

🔧 Ghost Proxifier Open Source — CLI-only, MIT licensed

⚠️ Important

About Windows security warnings:
The project does not yet have a Microsoft code-signing certificate. When downloading the installer through Microsoft Edge, some antivirus software may report a false positive and Windows SmartScreen may block the download or launch.

If Edge blocks the download, open Settings → Privacy, search, and services → Security and temporarily disable “Block potentially unwanted apps and downloads”. Re-enable this setting after downloading the installer.

If SmartScreen still blocks the installer, click More info → Run anyway in the blue warning dialog.

Only do this after confirming that the installer came from the official project Releases page and verifying its source.

Make sure the target application and its child processes are fully closed before injection.
Injection may fail if an existing instance is already running in the background. Fully exit the application before dropping its shortcut or .exe file into the window.

Use Cases

• Proxy AI coding tools such as Codex, Claude Code, and Antigravity.
• Use multiple VPN or proxy clients together while routing only selected applications to reduce virtual-adapter and routing conflicts.
• Proxy command-line tools, developer tools, and game clients that ignore system proxy settings.
• Assign different proxy nodes to different applications or accounts for network-level IP isolation.

Core Features

• Drag and drop: Drop a shortcut or .exe file to inject the target process.
• Automatic child-process tracking: Child processes are handled automatically without manual PID configuration.
• Per-process proxying: Proxy only selected applications while leaving other system traffic unchanged.
• Local DNS: Forward DNS queries through the proxy to reduce DNS leaks and poisoning.
• DoH / QUIC blocking: Prevent browsers from bypassing the proxy through direct HTTPS or UDP connections.
• Live monitoring: View process status, proxy status, traffic statistics, and automatic reconnection.

Supported Apps

Chrome	MS Edge	Firefox	Claude Desktop	Claude Code	Codex	Antigravity	Node.js	Python	SSH
FinalShell	Xshell	MySQL Workbench	BlueStacks X	CMD	PowerShell	CrossFire	HyperDown	...

In theory, all Windows applications using Winsock are supported. The list above contains tested and verified applications.

Quick Start

1. Download and launch Ghost Proxifier Pro from Releases.
2. Configure the upstream HTTP proxy and DNS settings.
3. Drop the target shortcut or .exe file into the window and start the proxied process.

No TUN/TAP virtual adapter or WFP kernel driver is required. Ghost Proxifier uses user-mode API Hooking based on MinHook to intercept Winsock functions and take over only selected processes and their child processes.
