They solve different problems
Use Safari Tab Groups for a small set of active contexts such as Work, Personal or a trip you are planning now. They are built into Safari, sync through iCloud and can be shared with other Apple users.
Use Tab Space when a window should be saved and closed, when groups are becoming an archive, or when the work crosses Safari, Chrome, Edge and Firefox.
Live groups and saved sessions
| Need | Safari Tab Groups | Tab Space |
|---|---|---|
| Core model | A persistent set of live Safari tabs | A saved session outside the browser, plus search across active tabs |
| Best for | A few current workspaces | Research, projects and reading queues kept for months or years |
| Organization | Group names and Safari Profiles | Names, tags, notes, favorites, search, merge and split |
| Protection | iCloud keeps current groups in sync | iCloud sync, automatic hourly through monthly snapshots and exports |
| Browsers | Safari | Safari; Chrome, Edge and Firefox 121+ with Pro multi-browser beta |
Use both without building a graveyard
The work is active
You want its tabs to remain a living Safari workspace, appear across Apple devices or be shared for collaboration.
The context matters more than the open tabs
You want to clear the browser, preserve the session, search it later and keep recoverable snapshots outside Safari.
When a project pauses
Save its window to Tab Space, close the tabs and remove the group. Reopen the whole session—or only one page—when the project becomes active again.
When the answer might be in another browser
Tab Groups organize Safari. Tab Space’s Browser Tab Switcher searches open tabs across supported browsers alongside saved sessions. Option-Tab can return directly to the original browser, window and tab without making you remember where the page lives.
Fact check
Safari behavior was checked against Apple’s current guides for Tab Groups and Safari iCloud sync.
Save the context. Close the tabs. Return when it matters.
