Tab Countdown

Set per-domain or per-URL countdown timers. Each tab gets its own independent countdown and is auto-closed when it expires.

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, can be toggled off in settings). 🟢 Live countdown widget — a small pill in the corner of the page shows remaining time at a glance. ⏸ Pause & Resume — pause countdowns to temporarily hold your time, and resume them whenever you're ready directly from the popup or options page. ➕ Extend timers — add 30s, 5m, 15m, 30m, or 1h 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.
