I thought wireguard was all cli based for now and no good UI (I use Linux desktop and Android phones)

Wireguard from the Mac App Store works successfully with Little Snitch (per-app firewall) and comes with a menubar icon that shows connectivity and allows quick switching. With the commandline-based version of Wireguard (installed from homebrew or wherever), Little Snitch sees all traffic as originating from the wireguard-go process. This is because the App Store version makes use of MacOS’s new network extension API, and Apple has only made that available to apps distributed through the App Store.
