RedQuits

RedQuits is a macOS utility that automatically terminates an application when its final window is closed. By monitoring the window count of each running app, it detects when the last visible window disappears and issues a quit command, preventing background processes from lingering after the user finishes with the program. This behavior mirrors the way many native macOS apps operate, but it extends the functionality to any application that does not already quit on window closure.

The tool is aimed at users who want to keep their system resources tidy without manually quitting each program. It is particularly useful for those who frequently open and close lightweight utilities or browsers and prefer the operating system to handle cleanup automatically. Because it runs as a background service, it requires no additional user interaction once installed.

RedQuits is distributed as a stable, core‑macOS package, meaning it is intended for standard macOS environments and does not depend on external frameworks or cross‑platform layers. Its implementation focuses on reliable detection of window events and safe termination of processes, offering a straightforward solution for managing application lifecycles.
