Tailscale releases Tailcat tool for rapid secure tunneling

Tailscale, the WireGuard‑based VPN service, has released a new lightweight utility called **tailcat**. The tool, hosted on GitHub, lets users copy files or stream data between machines that are already connected through the Tailscale network, functioning in a manner similar to the Unix `cat` command but over a secure, mesh‑connected overlay. The repository includes a minimal code base, clear documentation, and installation instructions for Linux, macOS, and Windows.

The project was highlighted on Hacker News, where the post received 20 up‑votes and one comment, indicating a modest but notable interest from the developer community. The discussion centered on tailcat’s simplicity and its potential to streamline file transfer workflows in environments that rely on Tailscale for secure connectivity. Users praised the tool’s ease of use and the fact that it requires no additional configuration beyond the existing Tailscale setup.

With tailcat now publicly available, developers can quickly add a command‑line file‑copy capability to their Tailscale‑enabled infrastructure. The project’s straightforward design and community feedback suggest it may become a handy addition for teams that need fast, secure file sharing without the overhead of traditional FTP or cloud services.
