Tailscale Releases Tailcat, A Netcat Built On Its Data Plane
Tailcat is a command line tool from Tailscale that sends text and files between two machines using Tailscale's WireGuard-based encryption and NAT traversal, without the Tailscale control plane. The receiving side prints an address; the sender passes that address to tailcat. The tool also serves SSH, files, web servers, and forwarded ports, and ships as a Go library and a WebAssembly build.
