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.

@sapsaldog Congrats on the launch Hoon. Cool tool
The battery threshold auto-stop is a genuinely thoughtful detail that most wake-lock utilities skip entirely. We've had long-running local processes fail silently because the Mac went to sleep mid-run, so this addresses a real pain point cleanly. How do you assert the wake lock under the hood? Are you using IOPMAssertionCreateWithName or a different IOKit approach?

What's the difference with OG Caffeine? https://www.caffeine-app.net/en/
This is the kind of tiny Mac utility I like, but the install path is the part I’d check first.
Is the GitHub release meant to be used directly, or is Open Caffeine still mainly a local build from Xcode for now?
How is this different from the original Caffeine or Amphetamine? Both are open source.I think calling this "Open" Caffeine is misleading.

Auto stop at a low battery level is a great feature, I’ve killed my battery doing long downloads many times.
