Hex Tunnel

Hex Tunnel is a high-performance Android VPN and proxy client designed specifically to bypass modern Deep Packet Inspection (DPI) and censorship systems. Powered by a customized sing-box core and advanced smart routing, Hex Tunnel provides seamless access to the free internet without sacrificing connection speed to local resources.

🌟 Key Features Smart Routing Engine: Dynamically routes traffic based on huge, regularly updated domain datasets. Local traffic connects directly, while censored domains are tunneled transparently. Hybrid Legacy Mode (WARP): A built-in Cloudflare WARP integration that uses advanced urltest balancing to scan for unblocked IP/Port combinations (e.g., 500, 4500, 2408), ensuring stable connectivity even during heavy DPI sweeps. Sing-box Core: Built on the bleeding edge of proxy technology. Supports standard protocols (VLESS, VMess, Trojan, Shadowsocks) along with modern transport layers like Reality and ShadowTLS. Split Tunneling: Easily exclude specific Android apps from the VPN tunnel to maintain native functionality (e.g., for local banking apps). Memory Optimized: Handles huge routing rulesets efficiently using atomic file operations and lazy loading mechanisms to prevent OOM errors and unexpected EOF crashes.
