Tab Space vs OneTab
OneTab defined the save-and-close tab workflow on Chrome and Firefox. Tab Space brings that workflow to Safari — as a native Mac app with iCloud sync, tags, search, automatic backups, and a companion app for iPhone and iPad. It even imports your existing OneTab list.
The same core idea
Both tools solve the same problem: too many open tabs. One click collapses your window into a saved list you can restore later, freeing memory and clearing your head. If you love OneTab's workflow, Tab Space will feel immediately familiar.
Where they differ
| OneTab | Tab Space | |
|---|---|---|
| Platform | Chrome, Firefox, Edge (browser extension only) | Safari on macOS — native Mac app + extension, plus an iPhone/iPad app |
| Where your data lives | Inside the browser's local extension storage | In a native app database outside the browser, synced with iCloud |
| Sync across devices | No built-in sync | iCloud sync across Macs, iPhone, and iPad — no account needed |
| Organization | A single chronological list of tab groups | Named sessions with tags, favorites, drag & drop reordering, and merging |
| Search | Browser page search | Full search across session titles, URLs, and tags |
| Backups | Manual export; data can be lost if the browser profile resets | Automatic backups with smart retention (hourly / daily / weekly / monthly), plus export to Text, Markdown, HTML, JSON |
| Extras | Share list as a web page | Safari keyboard shortcuts: close duplicate tabs, close same-domain tabs, copy URL as Markdown, open in another browser… |
| Migration | — | Imports OneTab exports directly |
| Price | Free | Paid, one-time purchase — no account, no ads, no data collection |
Why a native app instead of a pure extension?
- Your tabs outlive the browser. Sessions are stored in a real app database, not extension storage that disappears with a profile reset.
- iCloud sync without an account. Nothing to sign up for; your data stays in your own iCloud.
- Continue on iPhone and iPad. Save a session at your desk, reopen it on the couch.
- Automatic backups. Every save is protected by a retention schedule, so a mis-click never loses a session.
Switching from OneTab
Export your list from OneTab, then use Import from OneTab in Tab Space — your saved tab groups become Tab Space sessions, ready to tag and search.
