What is Floccus?

Floccus is a browser extension that synchronizes bookmarks across different browsers and devices without requiring a central cloud service. Synchronization runs through backends of the user's choice, such as a personal WebDAV server, Nextcloud, or a local file. The project is fully open source and available free of charge.

Core features

  • Cross-browser sync: Bookmarks can be synchronized between Firefox, Chrome, and other browsers.
  • Flexible synchronization methods: Users choose their own backend, from Nextcloud and WebDAV to local options.
  • Backup and restoration: Bookmark collections can be backed up and restored on new devices.
  • Structured management: Large bookmark collections can be organized with tagging and categorization.
  • No cloud dependency: Users who prefer not to store their data with a third-party provider run the backend themselves.

Who is Floccus for?

Developers and technically experienced users who already run a Nextcloud instance or a WebDAV server can integrate Floccus without much effort. Anyone without one of these backends will need to set one up first. That is the point where newcomers without self-hosting experience tend to get stuck. The extension itself is quick to install. Configuring the backend requires more.

Users who simply want to sync between two browsers and have no existing infrastructure will likely find Floccus more than they need.

Context & alternatives

Floccus belongs to the category of self-hosted knowledge management tools. It competes conceptually with browser-native sync solutions such as Firefox Sync or Chrome's Google account-based sync. Those require no configuration effort, but store data with the respective provider. Floccus reverses that trade-off: more control, more effort.

Anyone already running a Nextcloud instance gets bookmark synchronization with Floccus without introducing any additional dependency.
