The Fediverse (a portmanteau of “federation” and “universe”) is a network of interconnected servers (or so called instances) that make up federated publishing websites similar to Twitter, Instagram, and YouTube. It is made up by federation protocols like OStatus, and ActivityPub, and server software, most notably Mastodon, Pleroma, Misskey, and many others.
