Snapshots vs live state

Tab Session Manager automatically saves snapshots of your open windows and tabs — on a schedule, on close, or manually. If Chrome crashes or you accidentally close a window, you can reopen a saved session and get back to roughly where you were.

The key word is "roughly." A snapshot is a point-in-time copy. When you restore it, each tab reloads from its URL — your scroll position, form data, active ChatGPT conversation, half-written Notion doc, and any other in-page state is gone. You're back to the page, not back to the work.

Duotang doesn't snapshot anything. Workspace state is saved continuously as you work. There's no restore step because nothing is ever lost — your tabs are always loaded, always current.

Tab Session Manager doesn't organize active workflows

Tab Session Manager is a safety net, not a workflow tool. It has no concept of named workspaces you switch between throughout the day. You can't have a Work session and a Personal session open simultaneously and move between them — it saves what's open, it doesn't manage what stays open.

If your problem is "I need to switch between projects without reloading tabs," Tab Session Manager isn't designed for that use case.

One genuine advantage: sync

Tab Session Manager syncs saved sessions across devices via Chrome's built-in sync. If you work across multiple computers and want your saved sessions available everywhere, that's a real feature Duotang doesn't have — Duotang is local-first by design.

When Tab Session Manager is the right choice

  • You want automatic crash recovery and session history
  • You need cross-device access to your saved sessions
  • You want to archive named snapshots of tab states over time
  • You don't need live workspace switching — just a reliable backup

When Duotang is the right choice

  • You need to switch between projects throughout the day without losing your work
  • You work in apps where reloading from a URL means starting over — Notion, Gmail, ChatGPT, Figma
  • You want workspace state that's always current, not saved at intervals
  • You want named workspaces you can navigate between instantly

Persistent workspaces that never lose your place — free, no account.
