About Floccus

Floccus is an open-source browser extension that synchronizes your native browser bookmarks privately across browsers and devices. It works with the bookmarks you already have in the browser rather than asking you to move them into a separate bookmark service.

Sync targets include Nextcloud Bookmarks, Linkwarden, KaraKeep, WebDAV servers, any Git host such as GitHub or GitLab, and cloud storage like Google Drive or Dropbox. You can create as many sync profiles as needed, choose one-way or two-way sync, set the interval and pick which folder to sync, and configuration can be exported. It works in browsers that support web extensions, including Firefox, Chrome, Edge, Opera, Brave and Vivaldi.

A Floccus app for Android and iOS gives access to bookmarks on a phone, since most mobile browsers do not support the extension. The project is written in TypeScript and licensed under MPL-2.0. Support is available through a Matrix room, the Nextcloud Bookmarks talk channel and a Reddit community.
