Keyboard-driven VPN switcher for Linux.

---

byt swaps between NetworkManager-managed VPNs (WireGuard, OpenVPN) and Tailscale from a small Iced GUI or the command line.

Note

This is a very new project, you might stumble upon some bugs. I rarely use OpenVPN for example, so it's minimally tested. Feel free to contribute if you find anything wrong.

Features

• Iced GUI with keyboard navigation in mind
• WireGuard and OpenVPN via NetworkManager (D-Bus, polkit-authenticated)
• Tailscale via systemd
• Mutual exclusion: activating one VPN deactivates the others
• Import provider configs: byt import path/to/provider.conf
• Live state via NetworkManager D-Bus signals, no polling
• Single-instance lock

Requirements

• Linux with systemd
• NetworkManager
• For OpenVPN: the NetworkManager-openvpn plugin
• For Tailscale (optional): tailscale and tailscaled
• A running polkit authentication agent (most desktops include one)

Usage

byt                  # open the GUI
byt status           # print current VPN state
byt import foo.conf
byt --help
