Tab Domain and Page Countdown

About

Tab Domain & Page Countdown gives you precise control over how long you spend on any website.

Create rules that match a full domain (e.g. reddit.com), a specific subdomain (e.g. news.ycombinator.com), or an exact URL prefix. Each open tab gets its own independent countdown — timers don't interfere with each other, and closing one tab never affects another.

Features:

⏱ Per-tab countdowns — every tab runs its own timer independently
🌐 Domain or URL rules — match broadly by domain or precisely by URL prefix; more specific rules always win
🔔 In-page warning banner — a non-intrusive banner appears at the top of the page when time is running low (configurable threshold)
🟢 Live countdown widget — a small pill in the corner of the page shows remaining time at a glance
➕ Extend timers — add 5, 15, or 30 minutes directly from the banner or popup without leaving the page
🚫 Ignore rules — whitelist specific sites or URLs so they're never timed
⚙️ Sync across devices — your rules and settings sync via your Google account
🗑 Auto-close — tabs are automatically closed when their countdown reaches zero
Perfect for staying focused, managing screen time, or enforcing time limits on distracting sites.
