Capsomnia turns your Caps Lock key into a physical switch that prevents your MacBook from going to sleep. This lets you keep processes like AI agents, SSH sessions, builds, and downloads running even after you close the lid. If you prefer a different key, you can easily remap the shortcut. The Caps Lock light stays functional to show you when the app is active. This tool is free, open source, and includes no accounts or telemetry. It has already gained significant popularity with over 2 million views and thousands of downloads.
