Twinmark

Keeps your browsers' bookmarks the same on your Mac: Safari, Chrome, Brave, Edge and Vivaldi, through the Twinmark app.

Twinmark keeps your bookmarks the same in every browser on your Mac. You pick a reference (Safari, or a profile of Chrome, Brave, Edge or Vivaldi) and the browsers you choose follow it, within seconds of every change. • One reference, no conflicts. Add, rename, move or delete a bookmark in the reference and the other browsers follow. • Nothing is written before you agree. The first sync shows what it would do and waits for you, and so does any sync that would remove or move many bookmarks. • A backup before every change, and a one-click restore. • Works with your browsers' own sync: if a profile syncs with its account, your bookmarks reach your phone and your other computers too. • Your bookmarks stay on your Mac. The extension talks only to the Twinmark app on the same Mac: no accounts, no analytics, no bookmarks sent to us. The free version keeps one browser equal to the reference. Twinmark Premium adds more browsers and profiles at once, two-way sync from a browser back to the reference, a cleanup of bookmarks saved twice or no longer working, named snapshots, and backups kept longer. This extension is the browser half of Twinmark: it needs the free Twinmark app for Mac (macOS 14 or later), available at https://twinmark.app. Add it to each profile you want to sync.
