Agent Caffeine
Keep your Mac awake while AI agents work, also with the lid closed
A macOS menu bar app that keeps your Mac awake while AI coding agents work and lets it sleep when they are idle or waiting.
Overview
Agent Caffeine is a macOS menu bar utility designed for developers using AI coding agents. It automatically detects when agents like Claude Code, Codex, Cursor, and over 40 others are working, keeping your Mac awake during their operations—even with the lid closed. When agents finish or enter idle states, it lets your Mac sleep normally.
The app intelligently manages battery and heat, stopping at 20% battery on battery power and preventing unnecessary drain when no agents are active. It supports keeping your agent reachable from your phone for 1, 2, or 4 hours, can pause for 30 minutes to tomorrow, and integrates with your iPhone hotspot if Wi-Fi drops while an agent is working.
Agent Caffeine includes features like display dimming as the lid closes, sound notifications, and support for running long jobs through command line, MCP server integration, or direct agent commands. It works on up to 3 Macs per license.
