CR TUNNEL

CR TUNNEL is an Android VPN client for VLESS, XHTTP, VMess, Trojan, Shadowsocks, SOCKS and Hysteria2, built on Xray-core. Open source under GPL-3.0, no ads, no tracking, no in-app purchases.

Features

- XHTTP support (stream-up and packet-up) plus the usual VLESS transports (WebSocket, TCP, Reality, gRPC), VMess, Trojan, Shadowsocks, SOCKS and Hysteria2 - Auto optimize: every saved config is ping-tested for real latency, the fastest one is selected and connected automatically - Import configs from a subscription link or a QR code - Per-app proxy with 400+ package names pre-loaded - Auto-update for subscriptions - VpnService mode and a standalone Root mode

How it works

Xray-core handles the proxy protocols and routing, wired in through the AndroidLibXrayLite bridge. A native C tunnel (hev-socks5-tunnel) built with the Android NDK turns the local proxy into a device-wide VPN.

The tunnel source is compiled twice: once as a JNI shared library that runs inside the app for normal VpnService mode, and once as a standalone executable for Root mode, which does not need the Android VPN permission dialog.
