Hi Product Hunt 👋 I built this because of a specific, stupid moment that kept repeating: finishing for the day with thirty-odd windows open, and closing them one at a time like I was tidying a room by picking up individual grains of rice. Captain Kill Switch is one button in your menu bar. Click it, or hit a hotkey, and every running application closes. System processes are left alone. That is the whole product — there's no dashboard, no settings to tune, no account to make. A few things I decided deliberately: - It's free, and there's no signup. Nothing to churn out of. - It runs entirely locally. Anonymous stats and crash reports only — never your app list, never your files. - It really does close everything. Anything still open a couple of seconds later gets force-closed, unsaved work included. Save first. That bluntness is the feature, and I'd rather say it here than have you discover it. - It's genuinely cross-platform — macOS, Windows, Linux — plus a cks CLI through winget, Scoop, and Homebrew. What I'd most like to hear: what do you actually want spared? Some people want their music left running, some want their terminal untouched. That's the next thing I build, and I'd rather build the version you'd use.
