Stop your computer from sleeping — and stop your work apps from marking you away.
The classic keep-awake apps do exactly that, and that’s where their job ends. Your screen stays on, but Slack and Teams still mark you away.
The reason: they don’t check whether the machine is awake, they check how long you have been idle. Those are two different things, and KeepGreen handles both — with a separate switch for each, in case you only want one.
It never moves your cursor or interrupts what you’re doing. You won’t notice it running.
From 15 minutes to 8 hours, or indefinite. When the time is up it stops, no need to remember.
A single process and virtually no CPU at idle. Your battery won’t notice.
Available for Mac. Windows and Linux are on the way — they’re separate native apps, not one program repackaged, and that takes time.

The one with the most work ahead: every desktop handles idle time its own way.
Later onKeepGreen isn’t notarized by Apple, hence step two. The Control-click → Open shortcut stopped working in macOS 15. For the same reason, every update will ask you to grant the permission again.
You can verify the file is the original with shasum -a 256 KeepGreen.dmg and compare it against:
