## Decentralised social

Instagram, X and Facebook belong to companies that profile you and can censor or delete you overnight. The "fediverse" offers networks owned by their users.

  </Fragment>
  <Fragment slot="what">
    The X/Twitter alternative: a social network made of thousands of independent servers that talk
    to each other (the "fediverse").
  </Fragment>
  <Fragment slot="why">
    No single owner, no algorithm deciding for you, no arbitrary ban by one company. The feed is
    chronological, with no ads or manipulation.
  </Fragment>
  <Fragment slot="who">
    Everyone. Ideal for information accounts that want a presence no company can cut off.
  </Fragment>
  <ol slot="install">
    <li>
      On joinmastodon.org, choose a server (or "instance") that suits you, then create an account.
    </li>
    <li>
      Install an app (the official one, or Ivory, Tusky…) and follow accounts: you see the whole
      fediverse, whatever their server.
    </li>
  </ol>

    <span class="tool-tag">🌍 · open protocol</span>
  </Fragment>
  <Fragment slot="what">
    Not an app but a protocol: a social network where your identity is a simple key pair, like
    Bitcoin.
  </Fragment>
  <Fragment slot="why">
    No email, no password, no account anyone can delete. Your posts travel across decentralised
    relays and you truly own your audience: no one can ban you for good. You can even receive
    Bitcoin tips ("zaps") and switch apps anytime without losing your followers.
  </Fragment>
  <Fragment slot="who">
    Information accounts and creators who fear platform censorship and want a presence truly their
    own.
  </Fragment>
  <ol slot="install">
    <li>Install a client: Damus (iPhone), Amethyst or Primal (Android), or a web version.</li>
    <li>
      The app generates your key pair. <b>Back up your private key (nsec)</b> like a Bitcoin seed
      phrase: on paper, never shared.
    </li>
    <li>Create your profile, follow people, enable zaps to receive sats.</li>

    <span class="tool-tag">🌍 · federated · E2EE</span>
  </Fragment>
  <Fragment slot="what">
    Community chat, in the spirit of Discord or Slack, but federated and end-to-end encryptable.
    Element is the app, Matrix the network.
  </Fragment>
  <Fragment slot="why">
    You can host your own server (Synapse) and control your data. Perfect for a collective, a
    newsroom or an association that wants its own independent space.
  </Fragment>
  <Fragment slot="who">Communities and groups. See the metadata caveat below.</Fragment>
  <ol slot="install">
    <li>
      Install Element (element.io) and create an account on a public server, or on your own (section
      10).
    </li>
    <li>Join or create rooms, and enable end-to-end encryption for private conversations.</li>
  </ol>

    <span class="tool-tag">Insta · YouTube · Reddit</span>
    <span class="tool-tag">🌍 · open-source</span>
  </Fragment>
  <Fragment slot="what">
    The federated cousins of Instagram (Pixelfed), YouTube (PeerTube) and Reddit (Lemmy).
  </Fragment>
  <Fragment slot="why">
    Same logic as Mastodon: no single owner, no ad algorithm, no tracking. You post photos, videos
    or discussions without feeding a profiling machine.
  </Fragment>
  <Fragment slot="who">
    Those who want to leave Instagram, YouTube or Reddit without giving up the format.

<div class="box">
  <span class="lab">Metadata caveat</span>
  <p>
    Matrix encrypts <em>content</em> well, but in federation, participating servers see room
    membership and message timing. For highly sensitive use, prefer SimpleX/Session or self-host
    your server.
