Comparison
Perked vs Caffeine
Looking for a Caffeine alternative to keep your Mac awake while your coding agents work? Here's an honest look at how Perked and Caffeine compare — what each is best at, and which one fits your workflow.
What is Caffeine?
Caffeine is the classic, dead-simple Mac keep-awake app: a menu-bar icon you click to stop your Mac and display from sleeping. No conditions, no scheduling — that simplicity is the whole point.
The main difference
Caffeine is a manual on/off switch — you remember to toggle it before a long run and off afterwards. Perked watches for coding agents and toggles itself, so an overnight build or agent session never sleeps even if you forget.
