    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.

    Zulip is plagued with bugs, incompletenesses and annoyances, creating a ton of friction in everyday work. It doesn't matter how open you are when it's so much harder to work with than competitors.
