SonTab

English | 한국어

A lightweight, OneTab-style tab manager for Chrome. Click the toolbar icon to save every tab in the current window into a group and close them — freeing memory while keeping everything one click away.

Features

• One-click collect — saves all unpinned tabs of the current window as a group, then closes them. Tabs are closed only after the data is safely stored.
• Catalog view — groups sorted by creation time (newest first), inline group renaming, group locking, restore/delete per tab or per group.
• By-domain view — see every saved tab grouped by site (www. ignored), with the source group shown next to each tab. Shows the newest N tabs per domain (1/5/10/20, configurable) with expand/collapse.
• Search & filters — live search over titles and URLs, plus Starred and Locked-groups views.
• Starred tabs — star pages you want to revisit; they stay in the list even after being restored.
• Home-page decluttering — root pages like google.com or x.com are hidden automatically (starred tabs exempt; can be turned off).
• Import / Export — OneTab-compatible text format, plus importing a saved OneTab HTML page with group names and original creation dates preserved.
• Themes — auto (follows your device), light, or dark. Paper-archive design.
• 5 languages — English, Español, Français, 한국어, 日本語. Your browser language is detected on first launch.
• Private by design — no backend, no analytics. Everything stays in chrome.storage.local. Zero runtime dependencies.
