L×Box is a high-performance proxy client with no compromises. You choose the servers. You set the rules. You control the traffic. L×Box does exactly what you told it to. 12+ protocols, advanced routing, full DNS control, detour chains, per-app split tunneling and built-in diagnostics. No account, no ads, no analytics. No server network of our own. THE CORE IS OURS L×Box runs on sing-box-lx, our own fork of sing-box, developed together with the app. On top of stock sing-box the core adds: • AmneziaWG 2.0 — obfuscated WireGuard; • XHTTP — Xray transport, including stream-one; • VLESS + ML-KEM-768 — post-quantum protection; • MASQUE — Cloudflare WARP as a full node and a chain link. And it is tuned for real life on a phone: • DNS groups — several resolvers with failover; • smart urltest — pools, sticky selection, lazy health checks; • load balancing — connections spread across the pool; • self-healing of stuck connections; • idle tunnel sleep — less memory, less battery; • observability — DNS, connections and chains visible from the app. The core stays in sync with upstream; changes are verified on real devices. 12+ PROTOCOLS VLESS, VMess, Trojan, Shadowsocks, Hysteria2, TUIC v5, NaiveProxy, AnyTLS, SSH, SOCKS, WireGuard, AmneziaWG 2.0, MASQUE over QUIC/HTTP-3. Cloudflare WARP in one tap: registration right in the app, the private key is generated on your device and never leaves it — Cloudflare receives only the public half. WireGuard or MASQUE, optional AmneziaWG obfuscation. Import any familiar format: subscriptions and links, Base64, Xray arrays, WireGuard URI/INI, Amnezia vpn://, sing-box JSON configs, local files, plain text. SUBSCRIPTIONS WITHOUT MANUAL WORK Add a subscription — L×Box parses it and creates nodes with no duplicates. Unwanted nodes can be switched off and stay off through every update, even if the provider renames them. Processing rules with regex and capture groups rename, rewrite or disable nodes on every refresh — and show in adva
