🚀 YPtun — Multi-Engine VPN & Anti-Censorship Client

YPtun is a versatile VPN and proxy client designed for networks where conventional connections may be restricted. It combines Xray, sing-box, and additional tunneling engines with subscription management, routing profiles, DNS tunneling, and alternative transports. By offering several connection methods in one application, YPtun helps users adapt their setup to different network conditions.

🌐 Protocols & Connection Engines YPtun supports a broad range of protocols and transports, including:

- VLESS with Reality and XHTTP. - VMess, Trojan, and Shadowsocks. - Hysteria2 and WireGuard. - AmneziaWG for configurable traffic obfuscation. - TCP, WebSocket, gRPC, HTTPUpgrade, TLS, and uTLS fingerprint options.

The application can use Xray, sing-box, AmneziaWG, and supported specialized transports, automatically or through available configuration choices.

📡 Subscriptions & Server Management

- Import VLESS, VMess, Trojan, and Shadowsocks links. - Import Base64 lists, JSON-panel links, and raw Xray or sing-box configurations. - Import AmneziaWG configuration files or QR codes. - Support Happ-compatible routing profiles and bulk link imports. - Update subscriptions automatically, organize servers into groups and folders, and view available-node counts, descriptions, traffic usage, and remaining quotas. - Test nodes and select a responsive server, with fallback attempts when a connection fails.

🛡️ Alternative Tunnels & DPI Circumvention

- MasterDNS: Tunnel traffic through DNS queries, with resolver selection and an optional server-setup workflow. - WARP for Telegram: Run a separate WARP tunnel with a local SOCKS5 proxy for Telegram, independently of the main connection. - VK-TURN and olcRTC: Specialized transports designed to carry traffic through supported real-time communication services. - OpenFlux and Trust Tunnel: Additional transport options available in supported builds and configurations. - AmneziaWG: Use obfuscation settings to adapt WireGuard-based connections. - TLS fragmentation and multiplexing: Additional controls for supported connection paths.

Note: The project marks olcRTC as deprecated in its recent documentation. It may continue to work in existing builds but is planned for removal; consider the other supported transports for new setups.

🎯 Routing, DNS & Split Tunneling

- Configure proxy, direct, and block rules. - Use domain, IP, CIDR, GeoIP, GeoSite, and ASN-based routing where supported. - Choose which applications use the VPN and which bypass it. - Configure custom DNS and FakeDNS options. - Use an HTTP proxy through the active engine. - Route IPv4 and IPv6 traffic through the configured tunnel.

📱 Platforms & Requirements YPtun supports Android 6.0 or later. Builds are available for Windows and Linux, including x64 and ARM64 desktop options. iOS is listed as a beta platform. Choose the appropriate Android package for your device architecture.
