What it does
WireGuard supplies cross-platform VPN tunneling software built around peer public keys and a small network-interface model.
WireGuard is the tunnel component, not a subscription that supplies server locations. You configure peers using public keys and choose the machine that will act as the remote endpoint. This makes it useful for a home network, a server connection or infrastructure managed by someone comfortable with routing.
The official introduction emphasizes a small interface and IP roaming. Start with the installation and configuration material for your platform, then plan peer keys and allowed routes. A commercial VPN that uses WireGuard remains a different service with its own exit infrastructure and policies.
