Vortix

A terminal app, written in Rust, for running WireGuard and OpenVPN on Linux and macOS. It runs several tunnels at once, and has a kill switch that blocks traffic if a VPN drops, so the user's real IP never leaks. It's packaged in Arch Linux extra, Homebrew, crates.io and npm, ships .deb/.rpm packages, and is listed in awesome-rust and awesome-tuis.
