Open Caffeine is a native macOS menu bar app for keeping your Mac awake for a chosen duration. Pick presets, set a custom timer, toggle screen sleep behavior, use a global hotkey, show a countdown in the menu bar, and stop automatically at a low battery threshold. It is open source, Apple Silicon native, and built for people who want a simple, modern Caffeine-style utility without extra marketing menu items.

Hey Product Hunt! I built Open Caffeine because I wanted a simple, modern macOS menu bar app that keeps my Mac awake without extra clutter. It lets you start a stay-awake session for a preset duration, set a custom timer, keep the display on or only prevent system sleep, toggle everything with a global hotkey, and see the remaining time right in the menu bar. There is also a low-battery threshold so it can stop automatically when you are on battery power. The project is open source and Apple Silicon native. I’m launching it here to get feedback from macOS users, developers, and productivity folks: what would make this feel like the default lightweight utility you would install on a new Mac?
