What floccus is
floccus is free, open source software for syncing browser bookmarks and open tabs across browsers and devices. It can connect to Nextcloud Bookmarks, Linkwarden, KaraKeep, Git, WebDAV, Google Drive or Dropbox. Sync can merge changes in both directions or send changes one way. Users can sync open browser tabs instead of a local bookmarks folder, although the feature can sometimes duplicate tabs. Browser guides list Chrome, Firefox, Edge, Opera, Vivaldi, Brave and Kiwi; Safari is unsupported. Android and iOS apps are available. The Android app is in open beta and makes bookmarks available inside the app rather than syncing them with mobile browsers. floccus syncs browsers’ native bookmarks and does not provide a bookmark management interface. WebDAV and Google Drive support an encryption password for end-to-end encrypted sync, while Nextcloud Bookmarks and Git do not. The selected third-party storage service can access stored bookmarks. The creator, Marcel Klehr, works on floccus in his free time and is an employee at Nextcloud GmbH.
