TL;DR: OneTab is a 2013 URL list; Tabbiy is a modern Chrome side panel. Both do one-click save and memory freeing, but Tabbiy adds auto-grouping by domain, custom grouping rules, tab hibernation (visible in sidebar but freed from RAM), and import/export in JSON (free) / CSV/HTML/Markdown (Pro). Tabbiy is free, local-first, and tracks nothing; OneTab has no hibernation, no auto-grouping, and no sidebar.

OneTab pioneered one-click tab saving back in 2013, and for years it was the default answer to "Chrome is eating my RAM." But Chrome has changed — tab groups, side panels, Memory Saver, vertical tabs — and a URL list from 2013 doesn't fit modern workflows the way it used to.

If you've been searching for an OneTab alternative, this comparison breaks down where OneTab still works, where it falls short, and how Tabbiy fills the gaps without asking you to relearn everything.

What OneTab Does Well

OneTab's core idea is simple and still useful: click one button, every open tab closes and gets saved as a text list of URLs. This frees memory instantly and gives you a backlog of sessions to restore later.

Strengths worth keeping:

  • One-click memory freeing — closes all tabs at once
  • Lightweight — tiny extension, minimal permissions
  • Exportable lists — copy URLs as plain text
  • No account required — everything stored locally

For users who just want a panic button when Chrome gets slow, OneTab still works. The problems show up when you try to do anything more.

Where OneTab Falls Short

No Live Tab Management

OneTab is a list, not a workspace. When tabs are saved, they disappear from the browser entirely. To find one tab, you restore the whole session or dig through a flat URL list. There's no sidebar, no search, no way to peek at what's saved without restoring it.

No Auto-Grouping

OneTab dumps every saved tab into one undifferentiated list. If you save 40 tabs across three projects, they're all mixed together. Restoring means re-sorting manually every time.

No Partial Memory Control

OneTab is all-or-nothing: tabs are either open (using RAM) or saved (invisible). There's no middle ground for tabs you want to keep visible but unloaded.

Stale Interface

OneTab's UI hasn't meaningfully changed in over a decade. No dark mode, no keyboard shortcuts, no integration with Chrome's modern tab group features.

How Tabbiy Compares

Tabbiy takes OneTab's core promise — save memory, reduce clutter — and rebuilds it as a vertical tab manager you interact with in real time, not just a list you visit after the fact.

Vertical Sidebar vs Flat List

Tabbiy lives in Chrome's side panel. Every tab is visible, searchable, and manageable from the sidebar without switching windows. You can drag to reorder, click to switch, and press Alt+E to cycle through your most recently used tabs — built for comparing multiple pages side by side without reaching for the mouse.

OneTab's list only appears after you've already closed everything. Tabbiy's sidebar is where your tabs live the whole time.

Auto-Grouping Rules

This is the biggest gap OneTab never fills. Tabbiy auto-groups tabs by domain the moment you open them, and you can build custom rules that match paths, subdomains, second-level domains, and keywords to organize tabs into named groups automatically.

Tab Hibernation: The Middle Ground

OneTab forces a choice: open (RAM-heavy) or saved (invisible). Tabbiy adds a third option — hibernation. Hibernated tabs stay in the sidebar but unload their processes from RAM. Click to reload the page when you need it again.

This matters when you have tabs you need to keep accessible but aren't actively using. With OneTab, you'd either keep them open (wasting memory) or save them (losing access). Tabbiy lets you do both.

Session Save and Restore

Like OneTab, Tabbiy can save tabs to a staging list and restore them later. But because Tabbiy pairs saving with auto-grouping rules, restored sessions come back already organized — no manual re-sorting.

Memory Comparison

Both tools free memory by removing tabs from the active bar. The difference is granularity:

Privacy

OneTab stores data locally but has faced privacy questions over the years. Tabbiy is local-first with zero third-party tracking — no analytics, no remote servers, no account. Your tab data never leaves your browser.

Import / Export Formats

OneTab exports URLs as plain text. Tabbiy supports import/export of saved tabs and titles in JSON (free), or CSV/HTML/Markdown (Pro), so you can move tabs into notes apps, project trackers, or other browsers without reformatting.

How to Migrate from OneTab to Tabbiy

There's no direct import path from OneTab's URL lists — but migration is straightforward:

  1. Install Tabbiy from the Chrome Web Store
  2. In OneTab, restore the session you want to migrate — the tabs reopen in Chrome
  3. Open Tabbiy sidebar with Alt+D
  4. Click Save to capture the open tabs into Tabbiy's staging list
  5. Tabs are now saved in Tabbiy — restore them anytime, auto-grouped by domain

Tabbiy also supports import/export of saved tabs and titles in JSON (free), or CSV/HTML/Markdown (Pro), for backups and migration between browsers.

When to Stick with OneTab

Tabbiy isn't for everyone. OneTab is still the right choice if you:

  • Only need a panic button for memory emergencies
  • Never want a sidebar or vertical tab layout
  • Prefer the absolute simplest interface possible

If that's you, OneTab remains a fine tool. But if you've outgrown flat URL lists and want tab management that keeps up with how Chrome actually works in 2026, Tabbiy is built for that.

FAQ

Is Tabbiy a good OneTab alternative?

Yes. Tabbiy offers everything OneTab does — one-click tab saving, memory freeing, session restore — plus a vertical sidebar, auto-grouping rules, and tab hibernation that keeps tabs visible while freeing RAM. All of the above is free, and no account is needed.

Does Tabbiy save more memory than OneTab?

Both free memory by removing tabs from the active bar. Tabbiy also offers tab hibernation, which unloads tab processes while keeping them visible in the sidebar — useful when you want tabs accessible but not consuming RAM. OneTab has no equivalent.

Can I import my OneTab list into Tabbiy?

Yes. OneTab can export tabs as a URL list. Paste that list into Tabbiy by opening the sidebar, clicking Save, and restoring the URLs. Tabbiy also supports import/export of saved tabs and titles in JSON (free), or CSV/HTML/Markdown (Pro), for backups and migration between browsers.

Is Tabbiy free to use?

Tabbiy is free with unlimited tabs, auto-grouping, hibernation, and session save. The Pro plan adds more custom grouping rules, multi-format export (CSV/HTML/Markdown), and unlimited custom groups. Compare plans on the pricing page.

Does Tabbiy track my browsing data?

No. Tabbiy is local-first with zero third-party tracking. All tab data stays in your browser. Read the full privacy policy on the terms page.
