## What it is
Floccus is a free and open-source browser extension (with companion Android/iOS apps) that privately syncs native browser bookmarks and tabs across browsers and devices. It supports multiple sync backends including Nextcloud Bookmarks, Linkwarden, KaraKeep, WebDAV, Git, Google Drive, and Dropbox, with optional end-to-end encryption.

## Use cases
- sync bookmarks across chrome and firefox
- privately sync browser bookmarks between devices
- self-host my own bookmark sync server
- sync bookmarks with end-to-end encryption
- keep bookmarks in sync between work and home computers
- access my desktop bookmarks on android
- sync browser tabs across devices
- replace xmarks bookmark syncing

## When to avoid
- you need Safari support, which is not yet available
- you need bookmark syncing on mobile browsers, since most mobile browsers cannot run the extension
- you rely on Firefox bookmark tags, which floccus cannot sync due to missing APIs
- you want a hosted turnkey service with zero setup rather than configuring a sync backend
