Caps Lock keeps your Mac awake, even with the lid closed
Capsomnia turns Caps Lock into a physical switch that keeps your MacBook awake. Keep Claude Code, Codex, other AI agents, SSH sessions, builds, downloads, and more running after you close the lid. If Caps Lock is already assigned, choose another shortcut. The Caps Lock light still shows whether Capsomnia is active. The app is free and open source, signed and notarized. No accounts or telemetry. We’ve already seen strong interest in Japan: 2.3M+ views and 6,000+ downloads.
Hey Product Hunt! 👋 I’m Taketo, the maker of Capsomnia.
I built Capsomnia around a tiny but frustrating MacBook problem: sometimes you want to close the lid without interrupting a local task, an AI coding agent, SSH session, build, download, or long-running script.
Capsomnia turns Caps Lock into a physical keep-awake switch because the key already has a built-in status light. If you already use Caps Lock for something else, you can choose a different shortcut, while the Caps Lock indicator still shows whether keep-awake mode is active.
When keep-awake mode is on, Capsomnia disables system sleep so your work can continue with the lid closed. Turn it off to restore normal sleep. The app is free, open source, signed, and notarized for Apple silicon Macs running macOS 14+.
There are no accounts, network requests, or telemetry. Since sleep is disabled while the mode is on, please keep airflow, power, and battery use in mind.
