StayAwake is a free Chrome extension that stops your screen or computer from falling asleep, with a single click from the toolbar.
Instead of digging through your operating system's power settings every time you're giving a presentation, watching a long download finish, or just reading a recipe on your screen, StayAwake puts the control right in your browser toolbar.
What you can do with it:
- Keep Screen On — stops the display from dimming or turning off
- Keep PC Awake — stops the whole system from sleeping (the screen can still turn off on its own)
- Set an auto-off timer (15, 30, 60, or 120 minutes) so you never have to remember to turn it back off
- See your current mode at a glance via the toolbar badge
- Choose a default mode and timer that applies automatically every time Chrome starts
How to use it:
- Click the StayAwake icon in your toolbar
- Pick "Keep Screen On" or "Keep PC Awake"
- Optionally set an auto-off timer
No account, no tracking, no data collection — every setting is stored locally in your browser. Lightweight and built on Manifest V3.
