The Fediverse - Welcome to the open world of sharing

I'm writing this post to demystify the Fediverse as simply as possible—so you can find your place in it, whether you're completely new or have already heard about it without really knowing what it is. Get comfortable; we're about to embark on a journey.

Imagine space. A vast universe, made up of millions of stars, planets, continents, and cities. You choose where to settle down—but no matter where you live, you can communicate with anyone, anywhere in this universe. No one owns space. No capricious billionaire can buy it out on a Tuesday morning and decide to change the rules as he pleases. That's exactly what the Fediverse is.

The word itself is a portmanteau—"federation" plus "universe." A network of thousands of independent servers, run by ordinary people like you and me, who talk to each other using a common language. Thousands of communities, millions of people, zero big boss in charge.

Each server is called an instance. It's your town, your entry point into this universe. Mine is called OnJase.quebec. Others live on qlub.social, mastodon.social, mamot.fr, or tens of thousands of other corners of this French-speaking and international galaxy. And the beauty of it all? You can talk to anyone, no matter their instance, no matter where they are in the universe.

Your address in the Fediverse looks like this: @[email protected]—just like an email, your name followed by the server where you live. Simple, right?

What holds it all together is called ActivityPub—the common language all these servers use to communicate. It's thanks to ActivityPub that your Mastodon account can follow someone on Pixelfed who shares photos, on PeerTube who streams videos, or on Funkwhale who plays music. Completely different platforms that still understand each other. It's as if all the social networks on the planet finally speak the same language—except that here, no one owns it.

Some questions we hear often:
Is it free? Yes, most of the time. Instances are run by volunteers who pay for hosting out of their own pockets. If you can afford it, a small donation to your instance is always appreciated and makes all the difference.

Do you have to choose the right instance from the start? Not at all. If your instance no longer suits you, you move—and your followers move with you. No hostage-taking, no loss of contacts, no starting from scratch.
An official page that explains all this very clearly: docs.joinmastodon.org/user/mov…

And what if someone wanted to buy it all out like Musk did with Twitter? Good luck. To control the Fediverse, you'd have to buy out thousands of independent servers one by one, while new ones pop up every day. It's designed to never belong to anyone—and that's by design.

Are there any rules? It depends on each instance, but generally: respect others, caption your images for the visually impaired, use hashtags to be found, and report anything wrong to your administrators.

To see the scope of this universe at a glance, visit fediverse.party—all the platforms that are part of the Fediverse are there. The visuals speak for themselves.

The Fediverse is the internet as it should have been from the start—free, diverse, belonging to no one and everyone at the same time.

Welcome to the universe. My Universe 🏴󠁣󠁡󠁱󠁣󠁿 And yours!
