<p>Mastodon is a <strong>free, open-source social network server</strong> based on <strong>open web protocols</strong> like ActivityPub and OStatus. The social focus of the project is a viable decentralized alternative to commercial social media silos that returns the control of the content distribution channels to the people. The technical focus of the project is a good user interface, a clean REST API for 3rd party apps and robust anti-abuse tools.</p>
