StayAwake

About

Keep your computer awake with one click. Prevent sleep, screen lock & display timeout with quick timers. No tracking, no sign-up.

StayAwake keeps your computer awake with a single click — no more interrupted downloads, frozen presentations, or locked screens in the middle of a long read.
Just like a cup of coffee for your computer, StayAwake temporarily prevents your system from going to sleep, so nothing stops your work until you say so.
⚡ WHY STAYAWAKE?
Your operating system's sleep settings don't know when you're watching a dashboard, waiting for a large file to download, rendering a video, or presenting to a room. StayAwake overrides sleep mode and screen timeout only while you need it — then hands control right back.
✅ KEY FEATURES

One-click toggle — instantly keep your system awake, and switch off just as fast
Quick timers — stay awake for 30 minutes, 1, 2, 4, or 8 hours, then sleep settings automatically resume
Display control — choose "Screen on" to prevent display sleep and screen lock, or "Screen may sleep" to let the display turn off while the system keeps running in the background
Live awake counter — see exactly how long your session has been active
Total kept-awake stats — track your cumulative awake time at a glance
Status at a glance — the toolbar badge shows ON whenever StayAwake is active
