Fediverse

The fediverse is the loose network of independently run, interconnected social platforms — including Mastodon, Pixelfed, Lemmy, and others — that communicate using the open ActivityPub protocol instead of relying on one company's servers. Because each platform and instance sets its own rules, automation and posting behavior that works on one fediverse service can be treated very differently on another. This tag collects practical guides on what auto-posting and RSS distribution actually look like across the fediverse in 2026, platform by platform.
