Quit every open app with one command – politely, on macOS, Linux and Windows
lightsout is a free, open-source command-line tool for the end of the day: one command closes every open app, except the terminal you run it from and any apps you choose to keep.
What makes it different: it never force-quits. Each app gets the same request as Cmd+Q or clicking its X button, so apps with unsaved work still ask you to save. Anything still open after 10 seconds is left alone and listed at the end, so you know exactly what's left.
How it works: • Lists your open apps, numbered, and asks which one you're running it from so that one stays open • macOS: quits the apps in your Dock and closes Finder windows • Linux: closes app windows on X11 desktops, skipping desktop and panel windows • Windows: closes the apps on your taskbar and File Explorer windows • Keep apps open with a simple config file or by passing their names • Exits with an error code if anything didn't close, so it works in scripts
Install on macOS or Linux with Homebrew: brew install abhisheksinha1506/tap/lightsout
Or download the archive for your system from GitHub Releases. Single binary, written in Go, MIT licensed, tested end to end on all three platforms on every change.
Developers and power users who end their day with a dozen apps open and want a clean desk in one command.
Closing apps one by one is tedious, and force-quit tools risk losing unsaved work.

One command politely asks every app to quit, except your terminal and the apps you keep, then reports anything still open.
