Mastodon
Decentralized Twitter. No algorithm, no ads, you choose your server.
Description
Mastodon is a decentralized social network compatible with the Fediverse. Each server (instance) has its own rules, but they all communicate. No algorithm deciding what you see, no targeted advertising. You can migrate your account between servers without losing followers.
Strengths
- No algorithm or advertising
- Decentralized: no single company controls the network
- Account migration between instances without losing followers
- Mature mobile apps (iOS and Android)
Limitations
- Choosing an instance can be confusing at first
- Fewer users than Twitter/X
Recommended for
- Leaving Twitter/X without giving up microblogging
- Joining a themed community (tech, science, art)
Compared to alternatives
Mastodon replaces Twitter/X. Pixelfed replaces Instagram. Lemmy replaces Reddit. All three communicate via the Fediverse.
