TAB-GROUPER

// auto-group browser tabs by user-defined rules

+========================================================================+

v0.2 · [ACTIVE] · Chrome MV3 · JavaScript

Chrome / Brave MV3 extension that watches tab events and assigns each tab to a named group based on host, URL, title, or regex matchers. Rules sync via chrome.storage.sync, pinned tabs are left alone, and the popup exposes group-all / ungroup-all shortcuts.

> Six matcher types: hostEquals, hostContains, urlContains, titleContains, urlRegex, titleRegex
> Rules roam across signed-in browsers via chrome.storage.sync
> Debounced background service worker — first matching rule wins

----------------------------------------------------------------------------------------

> matchers

>hostEquals — exact host match (mail.google.com)
>hostContains — substring host match (github)
>urlContains — substring URL match (/pull/)
>titleContains — substring title match
>urlRegex / titleRegex — full regex for when the basics aren’t enough

> design choices

>First-match-wins ordering, so rules are easy to reason about.
>Pinned tabs are left alone — the extension respects user intent.
>Rules live in chrome.storage.sync so they roam with your browser profile.
>Background service worker debounces tab events to avoid thrashing.
