Tailcat: Secure Tunnels in Seconds (Tailscale)
Summary
Tailcat is described as a secure tunneling solution that uses Tailcat's data plane to provide end-to-end encrypted tunnels via WireGuard, DERP, and NAT traversal. It operates without a control plane and uses short connection tokens, with server and client modes, DNS TXT token publishing, and zero requirement for a Tailscale account or root access. The article covers usage examples such as piping stdin/stdout, exposing local ports, and an SSH server with no auth, as well as token structure and Go library usage examples.
