Relay - Share your phone's internet with your PC, no cloud

by•
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.

Hey Product Hunt 👋 I built Relay because tethering my phone to my laptop always felt like a compromise — either I needed root access, had to trust a third-party server, or fought with flaky USB drivers. Relay is different: it's a direct, encrypted WireGuard tunnel straight between your Android phone and Windows PC. No account, no cloud, nothing leaves your two devices. It handles full TCP/UDP traffic (games, video calls, installs all work), survives Wi-Fi switches and DHCP changes, and keeps DNS/IPv6 leaks locked inside the tunnel. Pairing takes seconds with a QR code or a 2-digit number. It's open source (GPL-3.0) and already has real everyday users. Next up: USB tethering, multi-client sharing (so anyone on your Wi-Fi can use your phone's connection), and iOS support. Would love your feedback — especially from anyone who's fought with tethering apps before!
