Built for real conversation

With 500 characters at your disposal and support for granular content and media warnings, you can express yourself the way you want to.

You’re a person, not a product

Mastodon is not a commercial network. No advertising, no data mining, no walled gardens. There is no central authority.

Always within reach

Multiple apps for iOS, Android, and other platforms thanks to a developer-friendly API ecosystem allow you to keep up with your friends anywhere.

A more humane approach

Learning from failures of other networks, Mastodon aims to make ethical design choices to combat the misuse of social media.
