What is Mastodon?

Mastodon is a social network based on open web protocols and free, open-source software. It is decentralized like e-mail.

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.
