What floccus is

floccus is free, open-source software for syncing browser bookmarks and open tabs across browsers and devices. It can sync through Nextcloud Bookmarks, Linkwarden, KaraKeep, Git, WebDAV, Google Drive, and Dropbox. Sync can merge changes in both directions or move changes one way by uploading or downloading. Users can sync open browser tabs instead of a local bookmarks folder, though the feature is experimental and can duplicate tabs. Browser guides list Chrome, Firefox, Edge, Opera, Vivaldi, Brave, and Kiwi; Safari is unsupported. Android and iOS apps are available, with the Android app in open beta. On Android, bookmarks are available inside the app rather than synced 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; Nextcloud Bookmarks and Git do not. The selected storage service can access stored bookmarks. floccus says its authors and app publishers do not receive the data users provide. Its plan is free, but using it requires a compatible storage service or server.
