Memory Saver
⭐
🔍
Live Tab Search
Instantly filter all open tabs by title or URL as you type. Hit AltS on Windows / OptionS on Mac to search across all your open tabs from anywhere. No more hunting through tab rows.

Sleep Tabs
Unloads inactive background tabs from RAM without closing them. Your tabs stay in the tab bar, freeing up memory until you click on them again. Reclaim hundreds of megabytes instantly.
RAM Saver
🔁
Dedupe Tabs
Scans all open tabs for identical URLs and closes every duplicate in a single action, keeping only one copy of each. Great for when you've accidentally opened the same page a dozen times.
Instant Clean
🪟
Merge Windows
Pulls all tabs from every other Chrome window into the current one. Stop context-switching between windows. Consolidate everything into one workspace with a single click.
Window Control
🔢
Tab Count Badge
Always know exactly how many tabs you have open. StacTab displays a live count badge directly on the extension icon in your toolbar, always visible and always accurate.
Always Visible
🔒 Fully private. No network requests, no analytics, no tracking. Only the permissions it needs: tabs, storage, context menus.

Workspace Vault

Your sessions. Safe, searchable, forever.

The Workspace Vault is StacTab's most powerful feature: a tab archive that lives entirely in your browser.

  • 📛
    Named Sessions Save groups of tabs as "Work", "Research", "Shopping", whatever makes sense to you.
  • 📦
    Flexible Archive Options Archive the current tab, all tabs, tabs to the left or right, or an entire tab group in one action.
  • 🪟
    Split Groups to Windows Explode any tab group into its own new Chrome window, perfect for deep focus sessions.
  • ♻️
    Smart Restore Restore individual tabs, all tabs from a domain, all tabs from a day, or an entire session in a new window.
  • ↩️
    30-Second Undo Accidentally archived the wrong thing? A countdown undo button lets you instantly reverse it.
  • 📤
    JSON & TXT Export Export your entire vault as structured JSON for backup or portability, or as a plain .txt reading list.
