Tab Tier

Smart tab lifecycle management for your browser

🗂️ Tab Tier — Smart Tab Lifecycle Management Tired of having 50+ tabs open and your browser eating all your RAM? Tab Tier is the first browser extension that automatically manages your tabs through an intelligent tiered lifecycle system. Unlike other tab managers that simply close your tabs or group them by domain, Tab Tier keeps ALL your tabs accessible while intelligently organizing them based on actual usage patterns. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS Tab Tier automatically categorizes your tabs into 5 tiers based on how actively you use them: 🔴 T0 — Fixed: Your essential tabs (Gmail, Slack, Notion). Always pinned, never demoted. 🟠 T1 — Active: Tabs you're currently working with. Fully loaded and ready. 🟡 T2 — Warm: Tabs idle for 1+ hour. Still in the tab bar but suspended. 🔵 T3 — Cold: Tabs inactive for 24+ hours. Grouped and minimized. ⚫ T4 — Archive: Tabs untouched for 7+ days. Removed from tab bar, saved for later. Tabs automatically move between tiers as you use them. Open an archived tab? It jumps right back to T1. Stop using an active tab? It gradually moves down. Close a tab by accident? Its previous tier and elapsed time are preserved so you can pick up exactly where you left off. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ✅ Automatic Tier Management — Tabs move between tiers based on your actual usage. No manual sorting needed. ✅ Smart Tab Groups — Each tier gets its own color-coded group in the tab bar, sorted left-to-right T0 → T3. ✅ Drag & Drop — Drag tabs between tier groups to manually promote or demote them. ✅ T0 Fixed Tabs — Pin your essential tabs (email, chat, tools) to T0. They never get demoted. ✅ Customizable Timers — Set exactly how long before tabs move between tiers. ✅ Tab Management Dashboard — Full overview of all your tabs with search, filter, multi-key sort, pagination (10/25/50/100/All/Auto), and bulk actions. Live-ticking elapsed-time column. ✅ Statistics View — Built-in dashboard with tier-distribution donut, top domains, longest-lived tabs, focus time by domain, 24-hour activity histogram, and a 30-day opened-vs-archived chart. ✅ Duplicate Detection — Visual preview panel groups duplicates by URL, pre-selects which copy to keep, and lets you confirm before cleanup. ✅ Memory Optimization — Reduces browser memory usage by suspending and grouping inactive tabs. ✅ Privacy First — All data stored locally. No data sent to external servers. Ever. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✨ RECENT HIGHLIGHTS & UPDATES ✨ 🎛️ Customizable Statistics Dashboard — Drag-and-drop reorder every stat card, set per-card width (¼ / ½ / ¾ / full), and resize the bar-chart label column per card. All preferences persist; a one-click "Reset order" button restores defaults. 🌐 Favicons & Percentages in Bar Charts — Every Top Domains / Top URLs / Focus-Time row shows a real favicon plus a percentage suffix computed against the full dataset, so you instantly see what share of your browsing each domain claims. 🔗 Top URLs by Focus Time — A brand-new card alongside Top Domains, ranking individual pages (query and fragment stripped) by cumulative focus time. ⏳ Time-Range Selector on Focus Cards — Switch the focus-time cards between All / 7d / 24h with per-day granularity, so rolling windows never pollute the cumulative view. 🔃 Auto-Sort Tabs by Recent Use — New Settings toggle keeps the most recently used tab at the top of each tier automatically, re-applied on every alarm tick across all windows. 📋 Smarter Tab Management Defaults — The table now opens sorted by Elapsed ascending (most recently used first); closed records show a neutral "○ closed" badge instead of looking like an error, and a dedicated "○ Closed: N" summary row replaces the old missing-warning. 🌍 5 Languages — Full localization in English, Turkish, Spanish, German, and French, with a built-in language selector (AUTO/EN/TR/ES/DE/FR) in the popup header and Settings page. 🎨 Dark & Light Themes — Beautiful Catppuccin Mocha (dark) and Catppuccin Latte (light) palettes across every page, with one-click toggle. ❓ In-Extension Help & Guide — Built-in 7-section guide (intro, tier system, progression, popup, Tab Management, Settings, tips), fully translated into all 5 languages. 📊 Statistics Dashboard — Tier distribution, top domains by focus time, 24-hour activity histogram, last-30-day opened/archived stacked bars, longest-lived tabs, plus a one-click "Reset Statistics" option. ⏱️ Advanced Sorting — Sort tabs by "Elapsed Time" ascending or descending to quickly find your most or least inactive tabs. Tier-first sort presets included. 🔍 Duplicate Preview — Safely review and choose which duplicate tabs to keep in a visual preview panel before cleaning up. 💾 Closed-Tab Retention — Closed tabs keep their previous tier and elapsed time instead of jumping straight to the archive, so reopening picks up exactly where you left off — even after a full browser restart. 🚀 Built-in Changelog & Roadmap — "What's New" screen keeps you updated on the latest features and upcoming plans, grouped by Added / Changed / Fixed. ⭐ Enhanced Management — Favicon support in the dashboard, instant UI syncing, robust tab state tracking across sleep/wake and session restore, and reliable wake-up of suspended/sleeping tabs. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ OPEN SOURCE & SUPPORT Tab Tier is open source!
