The Kosmos project is an open co-operative of people, who are developing a free, open-source, and user-centric alternative to centralized group chat platforms, based on widely used protocols and standards.

We also offer a variety of other, hosted communication and collaboration services, mostly focused on users and contributors of free and open-source software.

Kosmos Chat

Kosmos Chat (ex Codename 67P) is a group communication application, based exclusively on open protocols, standards, and data formats. All of its components can be either self-hosted or connected to hosted services. An alpha version is already in use by developers, and a public beta version is planned for early 2020.


Kredits are a system for tracking project contributions, enabling the fair and transparent use of project funds, as well as improving project management and governance. After a couple of years of experimentation, we finally started issuing kredits in production earlier this year. Check out the public contribution dashboard if you're interested.


We run a variety of public services, for which we will soon accept donations for user accounts.

  • XMPP (Instant messaging and group chat)
  • Mastodon (Federated social network)
  • Gitea (Code hosting and collaboration)
