TabNest - Tab Session Manager 🪺

Save & restore tab sessions with one click. Merge windows, close duplicates, and auto-save everything you had open.

A calm home for your tabs. Name a session, restore it later, merge scattered windows, and keep a live snapshot of what you were working on.

Stop losing a research trail every time you close the browser. TabNest turns “save → restore → tidy” into a one-click habit:

Sessions

• Save current window — optional name, favicons, tab count (5 sessions free, 200 with Pro);
• Restore — reopen everything in a new window;
• Lazy-load restore (Pro) — restore big sessions without loading every page at once;
• Rename or delete any time.

Quick cleanup (free)

• Merge windows — bring every tab into this window;
• Close duplicates — same URL kept once across all windows.

Auto-save (Pro)

• TabNest snapshots open tabs as you browse;
• Restore the last snapshot if a window disappears.

Backup & restore (Pro)

• Export all sessions as JSON;
• Import a backup to merge sessions on another machine.

Configurable

• Language: follow system, English, or 中文;
• Auto-save and lazy-load restore are Pro toggles.

Free & Pro

• Core features are free: save / restore (5 sessions), merge windows, close duplicates;
• Pro is a one-time purchase that permanently unlocks 200 sessions, auto-save, lazy-load restore, and backup / import — and supports ongoing development.

How to get started

After installing, open the toolbar panel, name the current window, and tap Save session. Restore it later in one click.

Please note

After installing, refresh tabs that were already open so the extension can run on those pages. Per browser rules, the extension may not work on browser internal pages (such as the New Tab page, Settings, or Downloads) or on the official store page. Open another website to test TabNest.
