About Capsomnia
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.
About Islet
Most notch utilities just draw a static shape over the cutout. Islet actually behaves like iPhone's Dynamic Island: native spring-physics expand/collapse, real-time HUDs for volume and brightness, a live music glance with full playback controls, one-tap audio output switching (no System Settings detour), plus calendar, weather, and a file tray you can drop into from anywhere. Built natively in Swift + AppKit, not Electron, fast and fullscreen-aware.
