No Sleep: Stay Awake
Stay awake with Caps Lock
Only for Mac

Mac
Keep your Mac awake while your AI works.
No Sleep is a menu bar app that keeps your Mac from sleeping — just turn on Caps Lock. While your MacBook is connected to a power adapter, it keeps running even with the lid closed.
■ The Mac that stays awake for the age of AI
・Hand a long-running task to your AI agent and step away—sleep won't cut it short.
・Run local LLM inference and training, or image and video generation, all the way to the finish.
・Long batch jobs and overnight automation run to completion with the lid closed.
・"Stay awake until the AI is done"—now it's a single keystroke.
■ Just press Caps Lock
・Caps Lock on ⇪ → sleep is blocked. Close the lid and your Mac keeps running.
・Caps Lock off → sleeps as usual.
・Prefer not to use Caps Lock? Choose “Keep Awake Now” from the menu instead — your typing stays lowercase, so you can keep working.
No need to open a settings window. Switch in an instant, without ever lifting your hands from the keyboard.
■ Handy beyond AI, too
・Keep large downloads and uploads going.
・Run video exports, builds, and renders all the way through.
・Keep working with the lid closed, no external display required.
・Stay connected for AirDrop, screen sharing, and file sharing.
■ Features
・See the status at a glance from the menu bar icon (the ⇪ fills in while active).
・Toggle Caps Lock control on or off (master switch).
・Launch automatically at login.
・A warning appears in the menu while running on battery.
・Works with Claude Code: keeps your Mac awake only while it’s working, and returns to normal sleep the moment Claude Code finishes.
■ Free, plus No Sleep Plus
Basic sleep prevention is free and unlimited. The following unlock with a one-time No Sleep Plus purchase:
・Stays awake through usage limits — if Claude Code hits its usage limit, No Sleep waits until the limit resets and the work resumes automatically.
・Timer — keep your Mac awake for a set time, like 1 hour or 8 hours. When it ends, normal sleep comes back automatically.
・Thermal safeguard — warns you in the menu when heat stays high. Turn it on and sleep prevention releases automatically so the Mac can cool down (off by default).
・Keep the display awake, too.
・Interruption log — if your Mac stops while you're away, it records when and for how long, and tells you when you get back.
■ Designed to be trustworthy
・Never accesses what you type—it only reads whether Caps Lock is on or off.
・No input monitoring or other special permissions required.
・No servers of our own and no data collection (in-app purchases are handled by Apple's App Store).
・Quit the app and normal sleep behavior returns instantly.
■ Please note (a macOS limitation)
Running with the lid closed works only while connected to a power adapter. On battery, closing the lid always puts your Mac to sleep (this is a macOS limitation that an App Store app can’t work around on its own). On battery, automatic sleep is still prevented while the lid is open. Also, running for a long time with the lid closed can make your Mac warm. Check that Caps Lock is off before putting it in a bag.

・No Sleep Plus: if Claude Code hits its usage limit, No Sleep stays awake until the limit resets and the work resumes automatically.
・New Shortcuts actions: Start Keeping Awake, Stop Keeping Awake, and Keep Awake For.
