Tailcat is a remix of Tailscale open source pieces to act like netcat, but over Tailscale's data plane, without Tailscale's control plane. Tailscale's data plane (magicsock) gives you point-to-point WireGuard-encrypted tunnels between two machines, using DERP relays for NAT hole-punching and as a relay of last resort. Unlike Tailscale itself, tailcat needs no account, no control plane, and no root/admin access. All connection metadata is exchanged out of band (e.g. by copy/paste or DNS TXT record) and everything runs in userspace via a gVisor netstack.
Please refer to the upstream project https://github.com/tailscale/tailcat for more information.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install tailcat, simply use the following command:
sudo snap install tailcat --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
