Shells the otter

Keep your tabs safe.

Suspend inactive tabs to free memory and save your browsing sessions with multi-layer backup protection. Like otters holding hands while they sleep, Shells keeps your tabs safe and connected.

Add to Chrome

Your Tabs Are Safe

Shells guards your tabs with multi-layer backup protection: auto-save, recovery snapshots, browser sync, and optional cloud sync. A backup health monitor shows the status of every layer.

Suspend & Save Memory

Uses Chrome's native tab discarding to automatically free memory from inactive tabs. Pinned tabs, tabs playing audio, and whitelisted sites are always protected.

Save & Restore Sessions

Capture every window, tab, and tab group. Expand a session to select specific tabs to restore, or restore everything at once — even as suspended.

Tab Groups Preserved

Shells faithfully saves and restores Chrome's native tab groups — names, colors, and collapsed state. No more lost group organization.

Close Duplicate Tabs

One click to find and close duplicate tabs across all windows. Protection rules are respected, and Shells keeps the best copy. Press Alt+Shift+D anytime.

Cloud Sync with E2E Encryption

Sync sessions to Google Drive, encrypted with a password only you know. One-time $25 Pro upgrade — no subscriptions, ever.

Import Your Data

Switching from OneTab, Session Buddy, Tab Session Manager, or Toby? Import your existing sessions with one click.

Keyboard Shortcuts

Suspend tabs, close duplicates, and manage sessions without leaving the keyboard. Configurable shortcuts for every common action.

Privacy First

Shells doesn't snoop. No analytics, no tracking, no third-party data sharing. Your browsing data stays on your device unless you explicitly enable cloud sync.

Two otters floating together in kelp — a raft

Why should you trust me?
