Score: 6.5/10 (Innovation: 6, Technical: 7, Documentation: 7, Utility: 6)

Headwire is a Go-based tool that adds NAT traversal to WireGuard using Tailscale's DERP relays and magicsock, allowing peers to establish direct connections when possible and fall back to relays. It provides a CLI and configuration format similar to WireGuard, making it accessible for users familiar with WireGuard. The project is experimental but offers a novel combination of existing technologies to solve a common networking challenge.

Target audience: devops, network engineers, backend developers
