GHOSTWIRE is the companion app for the GHOSTWIRE server manager, a small program that sets up and runs a WireGuard® VPN server on your own Linux machine. Pair the app once by scanning a QR code in the GHOSTWIRE web interface. From then on you can: • See at a glance which devices are online and how much they transfer • Add a device and show its config as a QR code to scan with the WireGuard app • Issue a new config when a phone is replaced – the old one stops working • Disable or delete devices instantly • Follow traffic per device over 24 hours, 7 and 30 days • Change the server's port, networks, DNS, routing and firewall options • Check the server's health and read its log • Set log and traffic history retention Private by design: • The app talks only to your server – there is no cloud service and no account. • It signs in with a token you can revoke at any time. • Self-signed certificates are pinned during pairing; Let's Encrypt certificates are checked normally. • No analytics, no tracking, no data collection. Requires a GHOSTWIRE server (Linux with kernel 5.6 or newer). WireGuard is a registered trademark of Jason A. Donenfeld. GHOSTWIRE is not affiliated with or endorsed by the WireGuard project.
