Capsomnia
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.
Capsomnia is a Mac company. It launched on Product Hunt on Jul 25, 2026, with 161 upvotes. Adamlead has 1 person on file at Capsomnia.
