Betula

Betula is an open-source, federated bookmark manager designed for one person. It combines personal bookmark organization with federated functionality, Fediverse support, and archives in a single application. It is intended for users who want to manage their own bookmarks while using software that supports the Fediverse. Archives are included as part of its bookmark management features, so organization, federation, and archiving are brought together rather than presented as separate tools. Betula can serve as an open-source replacement for the paid bookmark product Pinboard. Its federated design and Fediverse support are central to what it offers. One limitation to keep in mind when considering it as a Pinboard alternative is its single-user focus: Betula is specifically designed for an individual, and the available information does not describe it as a multi-user bookmark manager.
