Captain Kill Switch

Close running desktop apps from a single menu-bar or tray control.

Meet Captain Kill Switch

Captain Kill Switch is a small desktop utility for closing running applications together. It lives in the menu bar or system tray and offers a single action for clearing the workspace before a presentation, screen share, game, or change of task. The app is available for macOS, Windows, and Linux.

It first sends applications a normal quit request, followed by a short timeout before force-closing remaining processes. Critical system processes are excluded from the shutdown. The workflow needs no account and operates locally, with downloadable installers and command-line distribution options available. Captain Kill Switch is free and focuses on this one desktop-reset action rather than managing a larger productivity workspace.
