🐙 ProxiFyre – SOCKS5 Proxifier for Windows

ProxiFyre is a high-performance SOCKS5 proxifier for Windows, built on top of the Windows Packet Filter driver. It extends the original socksify demo with:

  • UDP support in addition to TCP
  • Multiple proxy instances
  • JSON-based configuration via app-config.json
  • Optional Windows Service mode for continuous operation

Licensed under the GNU Affero General Public License (AGPL) — see the LICENSE file for details.

✨ Key Features

  • Per-Application Proxying Route only specific applications’ traffic through SOCKS5 proxies.

  • Multiple Proxy Configurations Define different proxies for different applications or paths.

  • UDP & TCP Support Works with both TCP and UDP traffic for greater compatibility.

  • Windows Service Mode Install and run as a background service for always-on operation.

  • Flexible Matching Rules Match by executable name or by full/partial path — great for UWP apps.

  • SOCKS5 Authentication Support Username/password authentication supported, or run without if not required.

⚙ Configuration

All settings are stored in app-config.json in the application folder.

Example:

{
  "logLevel": "Error",
  "proxies": [
    {
      "appNames": ["chrome", "C:\\Program Files\\WindowsApps\\ROBLOXCORPORATION.ROBLOX"],
      "socks5ProxyEndpoint": "158.101.205.51:1080",
      "username": "username1",
      "password": "password1",
      "supportedProtocols": ["TCP", "UDP"]
    },
    {
      "appNames": ["firefox", "firefox_dev"],
      "socks5ProxyEndpoint": "127.0.0.1:8080",
      "supportedProtocols": ["TCP"]
    }
  ]
}

Notes:

  • appNames can be partial names (firefox) or full names (firefox.exe), or full/partial paths for folder-based matching.
  • supportedProtocols accepts "TCP", "UDP", or both.
  • If your proxy doesn’t require authentication, omit username and password.
