GoKawiilTailscale open-sources Tailcat, a lightweight peer-to-peer tunnel tool without accounts
Tailscale released Tailcat, a CLI and Go library that reuses pieces of Tailscale's data plane to create encrypted point-to-point connections like netcat, but without needing Tailscale's control plane or a user account. One machine runs a server and generates a short connection token, which the other side uses to connect; traffic is WireGuard-encrypted and initially routed through DERP relays before attempting a direct peer-to-peer upgrade via NAT traversal.
GoKawiil's interpretation of the reporting above, not reported fact.
By stripping out the control plane and account requirement, Tailcat lowers the barrier for quick, secure ad hoc connections between machines without installing full Tailscale or modifying system routing and DNS settings. This could appeal to developers needing lightweight, temporary encrypted tunnels for debugging, file transfer, or scripting, without the overhead of a managed mesh network.
- Tailcat strips out Tailscale's control plane, needing no account or root access.
- Connections are WireGuard-encrypted and bootstrap via DERP relays before upgrading to direct P2P links.
- It's fully open source, usable as both a CLI tool and a Go library.
