Mastodon is a free, open-source social network server based on ActivityPub where users can follow friends and discover new ones. On Mastodon, users can publish anything they want: links, pictures, text, video. All Mastodon servers are interoperable as a federated network (users on one server can seamlessly communicate with users from another one, including non-Mastodon software that implements ActivityPub)!


  • No vendor lock-in: Fully interoperable with any conforming platform
  • Real-time, chronological timeline updates
  • Media attachments like images and short videos
  • Safety and moderation tools
  • OAuth2 and a straightforward REST API

Install Mastodon in a few minutes on your server with Cloudron. To install Cloudron first, follow our setup steps.
