TL;DR: Chrome only auto-groups tabs in the limited "People also search for" scenario. Tabbiy's Auto button groups every open tab by domain in one click, and custom rules can match paths, subdomains, second-level domains, and keywords. Grouping is visual only — to actually save memory, hibernate the group instead.
If you regularly juggle dozens of Chrome tabs, manual grouping becomes a chore you eventually stop doing. The good news: Chrome now supports tab auto-grouping, and with the right setup you can keep your tab bar tidy without touching a thing.
Why Auto-Grouping Matters
When every project, research session, and work task shares one tab bar, finding anything takes seconds too long. Auto-grouping fixes this by:
- Grouping tabs by domain — all Gmail, Docs, and Drive tabs collapse into one labeled group
- Reducing visual clutter — a collapsed group is one compact chip instead of ten tabs
- Lowering context-switching costs — you always know where a category of tabs lives
How Chrome Auto-Groups Tabs Natively
Chrome's built-in feature groups tabs automatically in one limited scenario: when you open a link from a search engine, it creates a "People also search for" group. Beyond that, you're on your own — which is why most power users install a dedicated tool.
Auto-Group Tabs with Tabbiy Rules
For full control, Tabbiy lets you create custom grouping rules that run automatically the moment you open a tab. Here's how:
- Open the Tabbiy sidebar with the shortcut ALT+D
- Click the Auto button at the bottom of the list
- Tabs are instantly grouped by domain name
Creating Custom Rules
Want something smarter than domain matching? Open the Rules page and build rules that match paths, subdomains, second-level domains, and keywords. For example, a rule named Work can sweep every tab whose URL contains your work domain into one group — even tabs from different sites.
Ungrouping in One Click
Auto-grouping isn't permanent. Click Auto again and every group collapses back to plain tabs, giving you full control over when the tab bar is organized.
Grouping vs. Hibernation
Auto-grouping organizes your tabs visually; hibernation handles memory. The two work together — hibernate a whole group to free RAM, then reload it when you need it. If memory is your bottleneck, see Chrome Uses Too Much Memory? 7 Fixes That Actually Work.
