      Sethu Zulip has more potential than Mattermost. Zulip is also an open source alternative to Slack but approached in a different manner.

      hritcu Zulip does threaded conversations right, requiring every message to be in a thread and threads to be named. Like Mattermost, Zulip is also open source and can be self-hosted, but they also provide hosting, and for open source projects and research groups this hosting is free.
