Mastodon

Aplicación Descentralizada

A federated, open-source microblogging platform built on ActivityPub enabling users to post text, images, video and links across a global network of independently operated instances. Users on any instance can follow and interact with users on any other ActivityPub-compatible server in the fediverse. Each instance sets its own moderation policies; no central authority controls the network. Founded as an alternative to Twitter with a strong emphasis on user control, data ownership, and community-driven moderation.
