No Sleep keeps your screen — and your computer — awake for as long as your browser is open, without touching any system settings.
Flip the switch for an indefinite keep-awake, or set a timer (15 min, 30 min, or a custom duration) and No Sleep switches off automatically when it ends. A toolbar badge shows the time remaining at a glance.
Perfect for watching videos, giving presentations, long downloads, reading, or any time you don't want your display to dim or your machine to sleep.
No account, no tracking, no data collection. Made by tomi.
