OnionHop

What is OnionHop?

OnionHop is a privacy-focused desktop application that makes Tor network access simple and user-friendly for Windows and macOS users. Developed by center2055, this C# application launched in December 2025 and has quickly gained traction with over 200 GitHub stars. Unlike traditional Tor Browser usage, OnionHop provides system-wide anonymization options, allowing users to route all their traffic through Tor or selectively tunnel specific applications.

The application addresses a common pain point for privacy-conscious users: the complexity of manually configuring Tor for system-wide use. OnionHop automates this process while providing granular control over which traffic gets routed through the Tor network, making it accessible to both technical and non-technical users.

Getting Started

Installation is straightforward across both supported platforms:

Windows Installation

# Download from GitHub releases
# Run OnionHop-Setup-2.5.exe
# Or use portable version: OnionHopV2-Portable-2.5-win-x64.zip

macOS Installation

# Download OnionHop-2.5-macOS.dmg
# Move OnionHop.app to /Applications
# Or install via Homebrew:
brew install --cask center2055/onionhop/onionhop

On first launch, OnionHop performs several background tasks including IP status checks, downloading Tor relay country lists from Onionoo, and ensuring all necessary Tor components are available. The application may download required dependencies automatically on the first run.

Usage & Practical Examples

Basic Anonymous Browsing

For most users, Proxy Mode provides the simplest path to anonymous browsing:

1. Launch OnionHop and select "Proxy Mode"
2. Optionally choose an exit location from the dropdown
3. Click "Connect" to establish the Tor connection
4. Your system proxy is automatically configured to route traffic through Tor

This setup works well with web browsers and most applications that respect system proxy settings.

System-Wide Anonymization

For comprehensive traffic routing, TUN/VPN mode provides system-level anonymization:

1. Run OnionHop as Administrator (Windows) or provide system password (macOS)
2. Select "TUN/VPN Mode"
3. Enable bridges if your network blocks Tor
4. Click "Connect" to establish the VPN-style tunnel

This mode captures all network traffic, including applications that don't support proxy configurations.

Split Tunneling Configuration

The Hybrid mode allows selective application routing:

1. Enable TUN/VPN mode with Hybrid option
2. Configure which applications should use Tor vs. direct connections
3. Monitor traffic routing through the application's logging interface

This is particularly useful for users who need anonymous access for specific applications while maintaining normal speeds for others.

Performance & Benchmarks

OnionHop's performance largely depends on the underlying Tor network, which inherently introduces latency due to multi-hop routing. However, the application itself is lightweight and efficient:

• Resource Usage: Minimal CPU and memory footprint when idle
• Connection Speed: Typical Tor network speeds (significantly slower than direct connections)
• Startup Time: Quick application launch, with initial Tor connection establishment taking 10-30 seconds
• Stability: Reliable connection maintenance with automatic reconnection capabilities

The sing-box integration in TUN/VPN mode provides efficient packet routing, while the proxy mode offers better performance for compatible applications due to reduced overhead.

Who Should Use OnionHop?

OnionHop is ideal for several user categories:

• Privacy-conscious users who want system-wide anonymization without technical complexity
• Journalists and activists operating in restrictive environments who need reliable censorship circumvention
• Researchers and investigators requiring anonymous data collection capabilities
• General users in countries with internet censorship who need bridge support
• Developers and testers who need to simulate different geographic locations

The application is particularly valuable for users who need more than browser-only anonymization but don't want to manage complex Tor configurations manually.

Verdict

OnionHop successfully bridges the gap between Tor Browser's simplicity and system-wide anonymization needs. The dual-mode approach accommodates both casual privacy users and those requiring comprehensive traffic routing. While the project is relatively young and has some limitations, the active development and cross-platform expansion demonstrate strong potential. For users seeking accessible Tor integration on Windows or macOS, OnionHop offers a compelling solution that balances ease of use with powerful privacy features.
