The Fediverse is not one platform - it’s a universe of its own. It contains microblogging and longreads, videoclips and images, podcasts and music and much much more. It is running on a diversity of software, operated by different communities but all connected by open protocols. What holds it together isn’t a company or a business model — it’s a shared idea about how we communicate online and who holds the control of that.
More people than ever are questioning where their data lives, who owns their feeds and whether there’s an alternative to commercial platforms they no longer trust. FediDay is where people who care about answers for that come together — to show and tell, to build, to debate and think out loud to find solutions together.
Maybe you’re already on Mastodon, Pixelfed or PeerTube. Maybe decentralised social media touches your work without you thinking of it that way. Either way: If you have something to say, show, or ask: We want to invite you — developers, researchers, journalists, lawyers, artists, and everything in between.
The Fediverse and the ATProto/Bluesky community don’t always agree — and that’s fine. We’re inviting the conversation, particularly with those building bridges between our worlds.
FediDay 2026 takes place from September 11th to 13th aboard c-base in Berlin — a hackerspace located in the ruins of a spacestation that crashed here 3.5 billion years ago. We start Friday evening, when the best conversations happen anyway, and continue Saturday and Sunday across three stages.
