I built DotQuit — A lightweight macOS utility (~19MB) that finally quits apps when closing the last window

Hey [ r/SideProject ]( r/SideProject ), Every Mac user knows the mild annoyance: you hit the red button to close a window, thinking you're done, only to look down at your Dock and realize the app has been running in the background eating memory all day. I wanted an automated fix, but existing tools were either discontinued or bloated. So I challenged myself to build the lightest, most native macOS utility possible. What went into building it: Zero-polling architecture:

痛点：Mac 用户关闭最后一个窗口后应用仍在后台占用内存，现有自动退出工具要么停更要么臃肿，需要更轻量的原生方案。

目标用户：注重内存占用和 Dock 整洁的 macOS 重度用户，尤其是开发者、设计师等常开多应用的人群。

变现：Freemium：基础功能免费开源，Pro 版一次性买断/终身更新，可通过 Product Hunt、Reddit 和 Mac 效率社区获客。

MVP：用 Swift/SwiftUI 做一个菜单栏应用，通过 Accessibility AXObserver 监听最后一个窗口关闭事件，自动退出应用；加入白名单和 Option 键临时反转；2 周内可完成核心版本。

竞品：QuitAll、Swift Quit、RedQuits、AutoQuit、Hammerspoon 脚本

摘要：作者发布 DotQuit，一个约 19MB 的原生 macOS 工具，在关闭最后一个窗口时自动退出应用，解决应用后台常驻占内存的小痛点。产品已在 Product Hunt 上线，核心开源，Pro 版以 100% 折扣码做前 100 用户促销，但帖中未披露真实收入或付费用户数据。该方向独立开发可行，已有多个同类工具，差异化主要在轻量和原生体验。
