Agent Caffeine
Keep your Mac awake while AI agents work
What is Agent Caffeine?
Agent Caffeine is a menu bar app that keeps your Mac awake while AI coding agents work, also with the lid closed, and lets it sleep when they are idle or wait for you. It detects more than 40 agents (Claude Code, Codex, Cursor, opencode, Gemini CLI and others) and watches the commands they started, so a long build keeps the Mac awake too. Three modes: always, while an agent is open, or while an agent is working. 7-day free trial, then $9 once.
