Description
Relay turns your Android phone into a secure hotspot for your Windows PC — over an encrypted WireGuard tunnel, with no root, no account, and no server in between. Pair with a QR code or a 2-digit number and you're online in seconds. It handles TCP/UDP, survives Wi-Fi switches and DHCP changes, and keeps DNS/IPv6 traffic locked inside the tunnel. Kotlin/Compose on Android,NET 8/WinUI 3 on Windows, Go-based WireGuard core with gVisor. Open source (GPL-3.0), with real everyday users.

Could you build this?
No Relay relies on low-level networking, custom Android VPN service routing, userspace WireGuard tunneling, and Windows virtual network adapter drivers (Wintun) to bypass carrier tethering limitations without cloud servers or root.
What it would actually take: The architecture requires an Android app using Android's VpnService to intercept and forward raw IP packets into a userspace WireGuard implementation (Go/Rust/C), alongside a Windows desktop client bundling Wintun drivers and Windows Network Setup service APIs. Maintaining TCP/UDP state across dynamic network transitions without root access demands deep systems programming and network protocol engineering skills.
