Frequently Asked Questions
When should I use SleepWalk?
Use SleepWalk when an AI coding agent is running and you need to step away, move rooms, commute, or close your Mac without interrupting the task.
Which AI coding tools does SleepWalk support?
All of them. SleepWalk is not tied to a specific editor, IDE, CLI, or assistant. Codex, Claude Code, Cursor, terminal agents, and local tasks keep running because the Mac stays awake.
Can I close my MacBook lid while an agent is running?
That is the point. Start a SleepWalk session, close the lid, and let the agent continue while SleepWalk watches the limits you set.
How is SleepWalk different from Caffeine or Amphetamine?
Caffeine-style tools usually assume the lid stays open. Amphetamine can keep the display awake, which uses battery and can add heat. SleepWalk is built for agent runs with duration, battery, and temperature guardrails.
What happens when a limit is reached?
SleepWalk ends the session when the time, battery, or temperature limit you chose is reached, so the Mac is not kept awake indefinitely.
