Domain Tab Grouper

Domain Tab Grouper is a clean, modern, and lightweight productivity extension designed to instantly declutter your browser window.

If you are a heavy multitasker with dozens of open tabs, finding the exact page you need can be frustrating. This extension solves that problem with a single click. It scans your active window, identifies tabs belonging to the same website, and automatically organizes them into Chrome's native, color-coded Tab Groups. For maximum neatness, it even collapses the groups automatically, freeing up valuable space on your tab bar.

Key Features:

One-Click Organization: Instantly group tabs sharing the same domain (e.g., all YouTube tabs in one group, all Wikipedia tabs in another).

Smart Auto-Collapse: Newly created groups are automatically collapsed to immediately save space on your tab bar.

Intelligent Filtering: Only groups domains that have two or more active tabs, leaving single tabs untouched. It also safely ignores system pages (like chrome:// URLs) and pinned tabs.
