What is SlipStream GUI?

SlipStream GUI is a modern, cross-platform desktop application that provides a user-friendly interface for connecting to SlipStream VPN servers. It creates secure, system-wide tunneling through an HTTP proxy interface, allowing you to route all your internet traffic through an encrypted VPN connection. Built with Electron and Node.js, SlipStream GUI works seamlessly across macOS, Windows, and Linux platforms, offering a consistent experience regardless of your operating system.

​
Key Features

SlipStream GUI offers a comprehensive set of features designed for both ease of use and advanced functionality:
  • Cross-Platform Support: Native support for macOS (Apple Silicon and Intel), Windows (64-bit and 32-bit), and Linux
  • System-Wide VPN: Routes all traffic through SlipStream VPN automatically
  • Modern GUI: Intuitive interface with real-time status monitoring and logs
  • Auto-Configuration: Automatically configures system proxy settings for seamless operation
  • Proxy Bypass List: Exclude specific domains or addresses from the proxy (split tunneling)
  • Self-Contained: All dependencies bundled - no internet required after installation
  • Portable Mode: Windows portable version available with no installation required
  • Verbose Logging: Optional detailed logging for debugging and troubleshooting
  • Connection Testing: Built-in proxy connection tester to verify functionality
  • Real-Time Status: Monitor VPN connection status at a glance
  • Concurrent DNS Checker: Test many DNS servers at once and apply any working result with one click
SlipStream GUI requires a SlipStream server to connect to. You can deploy your own server using the slipstream-rust-deploy tool.

​
How It Works

SlipStream GUI creates a multi-layer proxy architecture to route your traffic securely: 
Your Applications
    ↓ HTTP/HTTPS
HTTP Proxy Server (127.0.0.1:8080)
    ↓ SOCKS5 Protocol
SOCKS5 Client (127.0.0.1:5201)
    ↓ Encrypted Tunnel
SlipStream VPN Server

​
Architecture Overview

The application consists of three main components:
  1. SlipStream Client: Runs the native binary that establishes a SOCKS5 proxy on port 5201, creating an encrypted tunnel to your SlipStream server
  2. HTTP Proxy Server: A Node.js server listening on port 8080 that converts HTTP/HTTPS requests to SOCKS5 protocol
  3. System Proxy Configuration: Automatically configures your operating system’s proxy settings to route all traffic through the VPN
This architecture ensures that all applications on your system can benefit from the VPN connection without requiring individual configuration.
The HTTP proxy runs on port 8080 and the SOCKS5 proxy runs on port 5201. Make sure these ports are available on your system.

​
Who Should Use It?

SlipStream GUI is ideal for:
  • Privacy-conscious users who want to secure their internet connection
  • Developers who need to test applications with different network configurations
  • Remote workers who require secure access to resources
  • Users in restricted networks who need reliable connectivity
  • Anyone looking for an easy-to-use VPN solution with full control over their server

​
Technical Requirements

Before installing SlipStream GUI, ensure your system meets these requirements:
  • macOS: 10.13+ (High Sierra or later)
  • Windows: Windows 10 or later
  • Linux: Most modern distributions (Ubuntu, Debian, Fedora, etc.)
  • Ports: 8080 and 5201 must be available
  • Disk Space: Approximately 150MB for installation
On Windows, you may need to run the application as Administrator for automatic system proxy configuration to work properly.
