Libervia


Libervia is a multifunctional communications application and decentralized social network published under the AGPL-3.0-or-later license.
Initially made for instant messaging and chat, Libervia developed additional functionality that can be used for microblogging, blogging, filesharing, audio and video streaming, and gaming. It has Atom feeds, and both WYSIWYM and WYSIWYG editors.
It uses XMPP. It also implemented ActivityPub in beta in late 2022, with a gateway that allows the two protocols to intercommunicate, aiming to have it in alpha in early 2023.
