An Android VPN client inspired by Slipstream-style architectures. It captures all system traffic using Android VpnService (TUN), then forwards packets through a tun2socks pipeline into a Slipstream transport (e.g. SOCKS5).

To improve performance and increase connection speed, the new version replaces the previous dependency:

with the optimized implementation:

Improvements:

• Higher throughput
• Lower latency
• Better connection stability
• More efficient resource usage

Slipstream Client is a lightweight and modular VPN client for Android:

• Captures all device traffic via Android VpnService (TUN)
• Uses tun2socks to convert IP packets (TCP/UDP/DNS) into user-space streams
• Forwards traffic into a Slipstream transport layer
• Supports full-tunnel mode (routes 0.0.0.0/0)

The design goal is a small Android shell (UI + lifecycle) with a transport backend that can be extended and swapped easily.

To set up a Slipstream server, use:

• Creates the device-wide TUN interface
• Installs routes + DNS
• Runs as a foreground service for stability
• Protects the tunnel socket to avoid routing loops

• Reads/writes raw IP packets from the TUN FD
• Maps TCP/UDP flows into user-space connections
• Forwards flows into the transport backend

• Handles transport logic
• Manages DNS routing
• Connects to Slipstream server

• Default: SOCKS5
• Designed to be pluggable (swap transports without rewriting the app)

• Full-tunnel mode (proxy all system traffic)
• SOCKS5 backend
• Modular design for experimenting with new transports
• Import/Export configs using URI format: slipstream://{base64}
• Designed for research and custom transport development

Note: UDP/IPv6 behavior depends on the tun2socks implementation and the chosen transport.
Proper DNS configuration is recommended to avoid leaks.

• Android 8.0+ (recommended)
• Android Studio
• Android NDK (for native tun2socks components)
• A reachable transport endpoint (e.g. a Slipstream with SOCKS5 server)
