THE FEDERATED WEB
Social media that belongs to its communities
What is federation?
When you send an email, you don't need to be on the same email provider as the person you're writing to. You can use Gmail, they can use Outlook, and it just works — because email is a federated system with an open standard that everyone agrees to follow. No one company owns email.
Federation for social media works the same way. Instead of one company running one giant platform where everyone has to have an account, federation means thousands of independent servers running compatible software that all talk to each other. You sign up on one server — one small community — but you can follow, reply to, and interact with people on any other compatible server in the world.
The collection of all these interconnected servers and communities is called the fediverse — a portmanteau of "federated" and "universe." It's not one platform. It's a constellation of thousands of communities that happen to speak the same language.
The BBS connection
The fediverse is, philosophically, the closest thing to BBS culture that exists on the modern web. A BBS was a small community, run by one person, with its own rules and character — but connected to a larger network of similar systems through FidoNet or other inter-BBS networks. You had a home system but could communicate across the whole network.
The fediverse works the same way. Your "home" is whichever server you sign up on. That server has its own moderators, its own community norms, and its own character. But your account on that server can follow and talk to accounts on any other compatible server in the fediverse, just like a FidoNet node could exchange echomail with nodes around the world.
The key difference is that the fediverse is built on the modern web rather than phone lines and bulletin boards. The result is more accessible but carries the same spirit: small communities, human operators, no algorithm deciding what you see, no advertisers deciding what you're worth.
Why it matters
No single owner
No one can buy the fediverse and change the rules overnight. If one server shuts down or goes bad, only that community is affected. Users can move their accounts to another server and take their followers with them.
No advertising
Most fediverse servers are run by individuals and organizations who fund them through donations or memberships. There are no advertisers, which means no tracking, no engagement-bait algorithms, and no content designed to make you angry so you'll keep scrolling.
Choose your community
Different servers have different focuses and different community cultures. There are servers for artists, scientists, journalists, programmers, tabletop gamers, and more — each with its own norms and moderation approach. You pick the one that feels like home.
Open standard
The protocol that makes federation possible — ActivityPub — is a published open standard. This means anyone can write software that speaks it, and the network isn't locked to any particular implementation. Competition and innovation happen at the level of the app, not the network.
Software platforms in the fediverse
Because ActivityPub is an open standard, many different platforms can talk to each other. A post from a Mastodon server can be seen and replied to by someone on Pixelfed, and vice versa. Here are the main platforms:
Mastodon
The most widely used fediverse platform. Microblogging — short posts, images, boosts (like retweets). Thousands of servers ranging from small personal instances to large general-purpose communities. The most accessible entry point to the fediverse.
joinmastodon.org →Pixelfed
Photo sharing, like Instagram but federated and without the algorithmic manipulation. Supports photo posts with captions, stories, and image descriptions for accessibility.
pixelfed.org →PeerTube
Video hosting, like YouTube but federated. Creators host their own channels on their own servers. Videos can be watched and interacted with from anywhere in the fediverse.
joinpeertube.org →Misskey / Calckey / Firefish
A family of fediverse platforms with a richer feature set than Mastodon — reactions, polls, better media handling. Popular in Japan and increasingly elsewhere. All federate with Mastodon and the rest of the fediverse.
misskey-hub.net →Lemmy & Kbin
Community discussion boards, like Reddit but federated. You subscribe to communities across different servers. Posts, comments, and upvotes all work across the network.
join-lemmy.org →WriteFreely & Plume
Blogging platforms for the fediverse. Write long-form posts that federate across the network. Your followers on Mastodon can read and respond to your blog posts directly.
writefreely.org →Real communities worth knowing
Fosstodon
A Mastodon server focused on free and open-source software. Active, well-moderated, and one of the friendliest communities on the fediverse for technically-minded people.
fosstodon.org →Mastodon.social
The flagship Mastodon instance run by the Mastodon development team. Large, general-purpose, and a reasonable default if you're not sure where to start.

The hardest part of joining the fediverse is choosing a server to start on. It doesn't matter much — you can always move later, and you can follow people on any other server regardless of where you sign up. The resources below help you find a community that fits.
