About Openbook
Openbook is inspired by the clarity of early Facebook, but built natively for the Fediverse. It targets personal, local, and thematic communities — not microblogging, not link aggregation.
Features
-
Federated
Follow people on any Fediverse server with @user@domain. ActivityPub inbox/outbox, WebFinger, HTTP Signatures — bidirectional federation.
-
Simple interface
Home feed, profiles, nested comments, likes, shares. Chronological ordering — no recommendation algorithms.
-
Open source
AGPL-3.0. No vendor lock-in. Run your own instance, read the code, fork if you need to.
-
Privacy-minded
No third-party analytics or ad trackers. Actor keys encrypted at rest. You control registration on your instance.
-
World timeline
A read-only window on federated content already relevant to your instance — not a global Fediverse index.
