Veilark

Independent Android VPN client with sing-box and TrustTunnel engines.

Veilark is an independent Android client for VPN profiles supplied by the user. It combines two network engines: sing-box for compatible proxy protocols and TrustTunnel for tt:// profiles. This repository contains the app, adapters, tests, and reproducible build instructions. It does not provide servers, VPN access, accounts, or subscriptions.

Features Android 10+ (minSdk 29), arm64-v8a and armeabi-v7a; English and Russian UI selected from the Android system or per-app language; separate sing-box 1.13.19 and TrustTunnel 1.1.4 modes; multiple subscriptions and profiles with refresh, selection, and deletion; import from a link, clipboard, file, or QR code; VLESS, Trojan, Hysteria 2, VMess, Shadowsocks, TUIC, and AnyTLS links; a compatible subset of sing-box/Xray JSON and Clash/Mihomo YAML; TrustTunnel tt:// links and lists of those links; per-application split tunnelling for both engines; offline Russia-direct geographic routing for sing-box; manual domain and CIDR rules for sing-box; Quick Settings tile, technical log, and on-demand latency checks; encrypted profile storage backed by Android Keystore. Import support is deliberately limited to formats Veilark can validate and convert safely. Compatibility is not claimed for arbitrary sing-box graphs, every Shadowsocks plugin, or every panel-specific subscription dialect.
