- NAT Traversal: WireGuard typically requires at least one publicly-reachable endpoint. Magic Wormhole's relay server handles NAT traversal for initial rendezvous, then attempts direct connection.
- Configuration: WireGuard needs config files with public keys and endpoints. Magic Wormhole just needs a temporary code.
- Layer: WireGuard operates at network layer (creates virtual interface, routes IP traffic). Magic Wormhole is application-level.
