Federation

highseas speaks both major open social protocols, so your instance joins the existing networks instead of starting a new island. You don't pick a side — see why we connect to both.

ActivityPub — the fediverse

Your instance is a first-class fediverse server. It exposes the standard endpoints other servers expect — WebFinger for discovery, actor documents, and inboxes/outboxes for delivering activities — so Mastodon, PeerTube, Lemmy and the rest can follow, reply to and boost your content, and you theirs. Identities look like you@yourdomain.social.

AT Protocol — the ATmosphere

highseas also participates in the AT Protocol network, where identity is portable across servers via DIDs and signed repositories. That means content can reach the Bluesky network, and the account model lets people move without losing their graph. See the AT Protocol for how that differs from the fediverse.
