💻 Source Code (open source) : https://github.com/YarooqH/tabstack Tired of 50+ squished, microscopic tabs slowing down your browser and killing your focus? TabStack automatically clusters same-site tabs into native Chromium tab groups. Keep your workspace organized, reclaim gigabytes of RAM, and focus on one task at a time. 🌟 KEY FEATURES ⚡ 1-Click Automatic Domain Stacking Instantly cluster same-site tabs into clean native Chromium tab groups. No more hunting through messy tab strips. 🎯 Accordion Focus Mode (Single-Stack Workflow) Automatically expands only the domain group you are actively working in while collapsing all dormant stacks. When you switch to another task, the previous stack collapses automatically so your tab bar never overflows. 💤 Smart RAM Saver (Native Tab Hibernation) Automatically suspends inactive background tabs using Chromium's native memory management API. Free up 50% to 70% of wasted browser RAM without closing tabs or losing form state. 🧼 Clean, Minimal & Clutter-Free UI Designed with an intuitive, distraction-free interface that gets completely out of your way. Simple, lightweight, zero bloat, and works seamlessly out of the box with no complex setup needed. ⚙️ Granular Controls & Whitelisting Set custom inactivity timeouts, adjust grouping sensitivity (root domain vs. subdomain), and whitelist essential tools so they never get grouped or put to sleep. ⌨️ DEFAULT KEYBOARD SHORTCUTS • Alt + Shift + T : Open TabStack Popup Dashboard • Alt + Shift + S : Stack all open tabs immediately • Alt + Shift + A : Toggle Accordion Focus Mode 🔒 100% PRIVATE & OFFLINE • Zero script injection — web pages remain 100% unmodified and secure. • 100% local operation — zero telemetry, zero analytics, zero data collection. • 100% Free & Open Source under the MIT License.
