TabMate is an experimental browser extension aimed at tackling the issue of "too many tabs". It automatically categorizes and organizes tabs, supports custom grouping, fixed tabs and groups, keyboard shortcut operations, and features a dark mode, along with options to group by date and domain, and utilize text and color labels. Currently compatible with Chrome and most Chromium-based browsers, including Edge, Brave, Opera, and Vivaldi, it supports macOS and Windows operating systems.
