A free, single-page web tool that keeps your computer awake and prevents screen sleep or lock. No ads, no accounts, no cookies, no tracking. One open browser tab is all it takes.
Try it: keepawake.dev
- Screen Wake Lock API — while the tab is visible, the browser asks the OS not to dim, sleep or lock the screen. The lock is re-acquired automatically when you come back to the tab.
- Silent audio fallback — a 1-second WAV of true silence, generated in memory and looped. While it "plays", the system stays awake, even with the tab in the background.
- Open keepawake.dev.
- Press Start.
- Keep the tab open. Tip: park it in another window or a second browser and keep working in yours.
A web page cannot move your mouse cursor. If your presence tool requires real mouse or keyboard events, no static website can do that. Keeping the machine awake and unlocked is what keeps most tools (Teams included) from marking you away.
One static HTML file. No framework, no build step, no external requests. Dark/light theme with light-dark() CSS. Deploys to GitHub Pages on every push to main via GitHub Actions.
