Choosing between tun2socks and MahsaNG depends largely on how much control, protocol support, and platform integration a user needs. Although both can be involved in routing network traffic through proxy or tunnel systems, they serve somewhat different purposes.
tun2socks is primarily a lightweight networking component designed to redirect traffic from a TUN interface through supported proxy protocols. MahsaNG, on the other hand, is an Android-focused application built around a more complete proxy and VPN-oriented experience, with support for multiple modern protocols and additional user-facing features.
This comparison looks at tun2socks vs MahsaNG across features, performance, compatibility, requirements, use cases, advantages, and limitations without treating either option as a universal choice.
What Is tun2socks?
tun2socks is a networking utility that redirects traffic received through a TUN interface to a proxy server. It can provide transparent proxying, allowing applications that do not natively support proxies to send their traffic through a configured proxy connection.
The xjasonlyu/tun2socks project supports multiple proxy types, including SOCKS, HTTP, Shadowsocks, SSH, and Relay, while also providing IPv4 and IPv6 compatibility. It can operate across Linux, macOS, Windows, FreeBSD, and OpenBSD.
Rather than functioning primarily as a consumer-facing VPN application, tun2socks is better understood as a networking component that can be integrated into different systems and applications.
What Is MahsaNG?
MahsaNG is an Android-oriented proxy and VPN application from the GFW-knocker project. It provides a graphical interface for configuring and managing proxy connections instead of requiring users to manually operate a standalone networking utility.
Its releases have included support for a broad selection of protocols and technologies, including XHTTP, SplitHTTP, QUIC, WireGuard, UDP Noise, and Hysteria2. It also includes application-oriented features such as VPN restart controls and an optional advertising-blocking feature.
This makes MahsaNG more focused on providing an integrated Android networking experience, while tun2socks is more focused on the underlying traffic-routing layer.

Feature Comparison
1. Traffic Routing
The main purpose of tun2socks is traffic redirection. It creates or works with a TUN interface and forwards network traffic toward a configured proxy. This approach allows applications without built-in proxy support to communicate through the proxy layer.
tun2socks can also be used in gateway-style configurations, where traffic from other devices can be routed through the system running the software.
MahsaNG approaches the same general problem from an Android application perspective. Instead of asking the user to manually configure a standalone TUN utility, it provides a VPN-style interface designed for use directly on an Android device.
2. Protocol Support
Protocol support is one of the areas where the two projects differ significantly.
tun2socks supports several proxy protocols, including HTTP, SOCKS, Shadowsocks, SSH, and Relay in its current implementation.
MahsaNG can expose a much wider collection of modern proxy technologies because it incorporates a broader proxy-core ecosystem. Its recent releases mention XHTTP, SplitHTTP, QUIC, WireGuard, UDP Noise, and Hysteria2 among its supported technologies.
Therefore, the comparison is not simply about which application supports more protocols. tun2socks is primarily a traffic-routing engine, while MahsaNG provides a broader mobile application and protocol-management environment.
Performance Considerations
Performance depends on several variables, including the selected proxy protocol, server location, encryption method, network quality, CPU resources, DNS configuration, and the implementation of the underlying networking stack.
tun2socks uses a user-space networking stack based on gVisor, and its project documentation provides performance benchmarks and memory-optimization information.
MahsaNG’s performance can vary according to the selected core and protocol. For example, different protocols may have different CPU, memory, latency, and bandwidth characteristics.
Neither option can guarantee faster internet access by itself. The proxy server and network path often have a greater impact on real-world speed than the traffic-routing application.
Compatibility
tun2socks Compatibility
One of tun2socks’ major characteristics is its broad operating-system support. The project lists Linux, macOS, Windows, FreeBSD, and OpenBSD compatibility.
Other implementations of tun2socks also target Android and iOS, showing that the general tun2socks approach can be incorporated into mobile applications.
This makes the technology useful for developers who want to integrate TUN-based proxy routing into different environments.
MahsaNG Compatibility
MahsaNG is primarily designed for Android. Its mobile-first approach means that users can configure proxy connections directly from an Android device without setting up a separate desktop networking environment.
Its Android focus is also one of its main limitations when compared with a cross-platform command-line networking component such as tun2socks.
Requirements
tun2socks Requirements
The requirements depend on whether a prebuilt binary or a source build is being used.
For normal operation, users generally need:
- A compatible operating system
- A TUN interface or supported TUN driver
- A compatible proxy server
- Correct routing configuration
- Appropriate permissions
- A configuration or command-line setup
Building from source may require additional development tools. Earlier versions of the project, for example, required Go modules and a C compiler, while current releases are distributed with prebuilt binaries for multiple platforms.
MahsaNG Requirements
MahsaNG is designed around Android, so its basic requirements are centered on:
- An Android device
- Permission to establish a VPN connection
- A compatible proxy configuration
- Sufficient system resources for the selected core and protocol
The exact Android version and compatibility can vary between releases. For example, the project has previously documented an Android 7-specific issue in one release and advised affected users to update.
Ease of Use
This is another major difference between tun2socks and MahsaNG.
tun2socks generally requires more technical knowledge. Users may need to understand TUN interfaces, routing, proxy addresses, ports, DNS, firewall rules, and configuration parameters.
Its command-line-oriented design is useful for automation and server environments but can make initial configuration less convenient for casual users.
MahsaNG provides a graphical Android interface, reducing the need to manually work with low-level networking commands. Users can manage configurations and VPN connections from the mobile application.
As a result, the learning curve is generally different rather than simply better or worse.
Use Cases for tun2socks
tun2socks can be suitable for scenarios such as:
- Routing an entire system through a SOCKS proxy
- Creating transparent proxy configurations
- Building networking tools and applications
- Server-side proxy routing
- Gateway configurations
- Linux networking projects
- Cross-platform proxy implementations
- Integrating proxy functionality into larger systems
Its gateway mode is particularly relevant when a system needs to route traffic originating from other devices on the same network.
Use Cases for MahsaNG
MahsaNG is more closely aligned with mobile-oriented scenarios, including:
- Managing proxy connections on Android
- Using multiple proxy protocols from a single application
- Establishing Android VPN-based traffic routing
- Switching between different configurations
- Using modern proxy technologies supported by its underlying core
- Managing connections without relying heavily on command-line tools
Its interface and integrated architecture make it more application-oriented than a standalone TUN networking utility.

Configuration and Flexibility
tun2socks provides considerable low-level flexibility. Its configuration can include parameters for the TUN device, proxy connection, MTU, network interface, UDP timeout, TCP buffers, logging, and other networking functions.
This type of configuration is valuable when precise networking behavior is required.
MahsaNG provides flexibility through its application and supported cores, but the experience is more focused on selecting and managing configurations rather than directly controlling every low-level networking parameter.
Security and Privacy Considerations
Neither tun2socks nor MahsaNG automatically makes a connection private or secure in every configuration.
The actual security characteristics depend on the proxy protocol, encryption, server configuration, DNS handling, routing rules, and the trustworthiness of the remote server.
Users should also understand that routing traffic through a proxy transfers some level of network visibility or trust to the proxy infrastructure. A technically capable routing tool does not by itself guarantee anonymity.
Which Environments Fit Each Option?
The distinction becomes clearer when considering the environment.
tun2socks is commonly suited to:
- Linux systems
- Windows systems
- macOS systems
- Servers
- Development environments
- Network gateways
- Custom applications
- Advanced proxy-routing setups
MahsaNG is commonly suited to:
- Android phones
- Android tablets
- Mobile proxy configurations
- Users who prefer graphical configuration
- Users who need access to multiple modern proxy technologies
These categories can overlap, but their primary design goals remain different.
Final Comparison
tun2socks and MahsaNG address related networking requirements from different directions. tun2socks is fundamentally a TUN-based traffic-routing component with cross-platform support, multiple proxy protocols, gateway capabilities, and extensive configuration possibilities. MahsaNG is an Android-focused application that combines VPN-style traffic handling with a broader collection of proxy protocols and a graphical management experience.
The choice between them therefore depends on the environment and the required level of control. A developer or advanced network administrator may be interested in tun2socks as a flexible networking component, while an Android user may be more concerned with application-level configuration and protocol availability.
