Description
Tailcat is a remix of Tailscale open source pieces to act like netcat, but over Tailscale's data plane, without Tailscale's control plane. Tailscale's data plane (magicsock, internally) gives you point-to-point WireGuard-encrypted tunnels between two machines with DERP as the NAT-hole-punching communication side channel and the ultimate relay-of-last-resort if NAT traversal fails. Instead of using the Tailscale control plane, all tailcat connection metadata is exchanged out of band, however you want.
The tailcat CLI (in cmd/tailcat) is built on the tailcat Go library (importable as github.com/tailscale/tailcat).
You don't need a Tailscale account, root/admin access on the machine (it doesn't alter your machine's routing tables, DNS, etc.). It's just a userspace library and CLI tool.
