Tailscale releases Tailcat: Open-source WireGuard tool without the control plane
alexcovo_eth · x · 2026-09-01
Tailscale has released tailcat, an open-source Go package and CLI tool that allows users to utilize Tailscale's data plane (WireGuard encryption + NAT traversal + DERP relay) without the control plane.
Key Features:
- Zero Account Management: No logins, passwords, SSO, or admin permissions required.
- Decentralized: No IP address assignment, user management, or dependency on Tailscale's company services (fully independent if you run your own DERP server).
- Use Case: Functions like netcat but routes traffic through Tailscale's network stack, focusing purely on data transfer.
This project targets developers who need raw networking capabilities without complex enterprise management overhead.
