Haunted Tab
A page that knows when you leave for other tabs — it decays while you’re gone, whispers into the tab title, and logs exactly how long you abandoned it.
This browser can't be haunted
Haunted Tab needs the Page Visibility API and a canvas. Please open this in an up-to-date desktop or mobile browser (Chrome, Edge, Firefox or Safari).
Nothing to confess… yet.
Switch to another tab or app, wait a moment, then come back. Your little ghost will remember.
🔒 100% on your device — the diary lives only in your browser's localStorage, nothing is uploaded. Switch tabs and watch the title and favicon change. The longer you neglect it, the sadder it gets.

About Haunted Tab
Haunted Tab is a free browser toy that haunts you when you neglect it. Open it in a tab, then switch to another tab—the page knows you've left. It starts to decay, whispers your abandonment time into the tab title, and keeps an exact log of every time you wandered off. No sign-up, no data collection, no servers involved. Your creepy browser tab lives entirely in your browser.
The tool uses the Page Visibility API to detect the exact moment you switch tabs. While you're gone, the page literally decays—colors fade, text warps, and cryptic messages appear in the tab title itself, counting how long you've been absent. When you return, it logs the abandonment duration so you can see exactly how much time you spent elsewhere. It's a playful, slightly unsettling way to become aware of your tab-switching habits.
Perfect for anyone curious about how the Page Visibility API works, procrastination watchers, or developers testing browser focus detection. The tab never sleeps. It never forgets. All tracking happens locally on your device—no cloud, no analytics, no tracking pixels sent anywhere. Just you, your browser, and a haunted tab that knows precisely when you've moved on to something else.
