L×Box

📦 L×Box — Advanced sing-box VPN Client for Android

L×Box is an open-source Android VPN and proxy client powered by sing-box-lx, a customized sing-box fork with AmneziaWG 2.0 and native XHTTP support. It combines extensive protocol support, multi-subscription management, smart routing, speed testing, WARP tools, and advanced configuration controls in a modern Android interface.

🌐 Protocol Support

L×Box supports a wide range of proxy and tunneling protocols:

• VLESS • VMess • Trojan • Shadowsocks • Hysteria2 • TUIC v5 • NaïveProxy • AnyTLS • SSH • SOCKS • WireGuard • AmneziaWG • MASQUE

VLESS configurations can use advanced features such as REALITY, XHTTP, TLS, uTLS, and supported encryption options.

📥 Subscriptions & Imports

Users can add configurations through:

• Subscription URLs • Individual proxy links • WireGuard URI/INI files • Amnezia vpn:// links • Raw sing-box JSON • Local TXT/JSON files • QR codes and supported share links

Multiple subscriptions can be enabled or disabled independently. Cached subscription data can also restore nodes after restarting the application.

⚡ Testing & Smart Selection

L×Box includes built-in latency and speed testing for evaluating servers directly from the device.

Automatic selection groups can choose suitable nodes, while detour chains allow compatible configurations to route traffic through multiple servers.

☁️ WARP & AmneziaWG

Dedicated WARP tools support Cloudflare WARP through WireGuard and AmneziaWG.

Available options include endpoint selection, custom endpoints, persistent keepalive, and experimental WARP scanning for testing multiple endpoint variants.

🔀 Advanced Routing

The sing-box-based routing system supports rules for domains, IP ranges, applications, and other traffic attributes.

Routing actions include:

• Proxy • Direct • Block • Detour / chained routing

Per-application routing and custom DNS configuration provide additional control over how device traffic is handled.

📊 Monitoring & Diagnostics

L×Box provides tools for connection management and troubleshooting:

• Latency and speed tests • Traffic statistics • Connection logs • Node diagnostics • Configuration validation • JSON inspection and editing • Memory information

Subscription updates, backups, and configuration management are also available.

🎨 Android Experience

L×Box provides English and Russian interfaces with a modern Android UI. It uses Android's TUN/VPN interface for device-level routing and supports persistent connection settings and configurable networking options.

🔐 License & Open Source

L×Box is licensed under the GNU General Public License v3.0 (GPL-3.0).

The application links against libbox from sing-box, which is licensed under GPLv3-or-later. Therefore, compiled L×Box APKs are combined GPLv3 works and must remain under GPLv3 when redistributed.

The developer may offer a separate commercial license for the original L×Box code, but this does not remove the GPLv3 requirements of libbox or other third-party components and does not by itself permit distributing the complete application as proprietary software.

⚠️ Important: L×Box is a client and does not provide guaranteed VPN servers. Connection quality depends on the selected server, subscription, protocol, routing configuration, and network conditions.

✨ L×Box combines sing-box-powered tunneling, extensive protocol support, multi-subscription management, smart routing, WARP/AmneziaWG tools, speed testing, and diagnostics in one powerful Android client.
