About
A tiny tool that does one thing well
NoScreenSleep exists because the obvious search — “keep my screen awake” — used to end in a sketchy download, a menu-bar app you only needed once, or a settings maze. A browser tab can do it better.
Why it exists
Modern browsers ship a purpose-built capability — the Screen Wake Lock API — that keeps a display on while a page is visible. It's private by design, needs no installation, and works on nearly every current device. The only missing piece was a fast, honest front door to it. That's this site.
The rules it's built on
- Free, for real. No accounts, no paywall, no “pro” tier. The tool is a static page; providing it costs almost nothing.
- Private by architecture, not by promise. There are no analytics and no cookies, so there is nothing to leak. See the privacy page for the complete list.
- Fast beats pretty. Pages are pre-rendered HTML with system fonts and almost no JavaScript — the tool is interactive immediately, even on hotel Wi-Fi.
- Honest about limits. A web page can't override a closed lid, a hidden tab or an enforced lock policy — and this site says so rather than pretending otherwise.
- Every page earns its place. Each guide answers a different question for a different device or browser. No filler, no keyword-stuffed duplicates.
What it's not
It's not an app store product, a background service, a battery manager or a system tweaker. It's one web page, doing one job, that gets out of your way.
