Meet xBrowserSync

xBrowserSync is designed to keep bookmarks synchronized while minimizing dependence on an identifying user account. Its privacy model uses client-side encryption so the synchronization service is not intended to read the contents of the bookmark collection.

It is primarily a synchronization layer, not a rich read-later archive or team knowledge base. Users should check supported browser versions and their chosen sync endpoint before adopting it, especially when relying on a community-operated public service.
