Your self-hosted, globally interconnected microblogging community.
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)!

Libervia est un outil tout-en-un pour gérer tous vos besoins en communication: messagerie instantanée, (micro)blogage, partage de fichiers, albums photo, événements, forums, gestion de tâches, etc.
