Betula

Betula is a free federated self-hosted single-user bookmarking software for the independent web with archival support. Use it to organize bookmarks, maintain a linklog or a personal web archive. It supports W3C ActivityPub, meaning Betula instances can be subscribed to from other Fediverse software like GoToSocial, Mastodon, and Lemmy. Betula instances can follow other Betula instances, and users can repost other users' bookmarks.
