Monitoring, dashboards & kiosks
Keep your screen on for as long as you need
Some screens are for looking at, not touching. When a display exists to be watched — a dashboard, a queue, a live feed — the last thing you want is it timing out. One tap keeps it on.

Ready when you are
Keep this tab visible — browsers pause wake locks on hidden or minimized tabs.
Built for “eyes on” time
A display that nobody touches still counts as “idle” to the operating system, so it goes dark right before you need it. This tool is made for exactly that pattern:
- Ops and status dashboards — CI builds, deploys, uptime boards and analytics walls.
- Kiosk and reception screens — schedules, menus, and sign-in stations that must stay visible all day.
- Live monitoring — baby monitors, security feeds and smart-home panels running in a browser tab.
- Second-screen reference — an old laptop or tablet propped up showing documentation while you work.
Keeping the screen on for hours at a time
- Plug the device in. An always-lit screen is the largest power draw on most devices — chargers remove the worry.
- Lower the brightness, not the lock. Full brightness for hours is rarely needed; dim the screen itself and let the wake lock handle the timing out.
- Give it its own window. Put this tab in a small side window. It stays visible (so the lock holds) without interfering with your real work.
- Set a generous timer anyway. Choose 1 hour or a custom duration as a safety net; you can always restart it.
The countdown is clock-based, not timer-based
Browsers throttle JavaScript timers in busy tabs, which makes naive countdowns drift. Ours measures against the clock, so “30 minutes” means 30 real minutes — and if the timer expires while you're briefly on another tab, the lock releases the moment you return.
Screen on vs. screensaver vs. system sleep
These are three separate mechanisms. A screensaver is cosmetic animation; a screen-off timeout turns the panel dark; system sleep suspends the whole machine. A wake lock handles the first two by keeping the display active. If the machine itself suspends on a schedule, that's an OS power setting — see prevent screen sleep for the device-level fix.
