What it is

floccus syncs browser bookmarks and open tabs across supported browsers and devices. It works with Nextcloud Bookmarks, Linkwarden, KaraKeep, Git, WebDAV, Google Drive, and Dropbox, and offers two-way merge sync or one-way uploads and downloads. floccus syncs browsers’ native bookmarks rather than providing its own bookmark-management interface. Its guides list Chrome, Firefox, Edge, Opera, Vivaldi, Brave, and Kiwi; Safari is unsupported. Android and iOS apps are available, though the Android app is in open beta and keeps bookmarks inside the app rather than syncing them with mobile browsers. Tab syncing can replace a local bookmarks folder, but may create duplicate tabs. WebDAV and Google Drive support an encryption password for end-to-end encrypted sync; Nextcloud Bookmarks and Git do not. floccus describes itself as free and open source, with no ads or data collection. Its plan is free and requires a compatible storage service or server. Selected storage services can access stored bookmarks.
