   Slack vs Mattermost Comments

   Comment by davaga6837 · Sep 18, 2025

   It's a fine alternative. It's paid and proprietary, but has ample support and reliable software. If data privacy is an issue stick with mattermost, rocket.chat or some other software. Weirdly enough, mattermost isn't listed as an alternative to slack even though it should be.

   Zulip vs Mattermost Comments

   Top Positive Comment by hritcu · Jul 17, 2020

   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.

   Top Negative Comment by KazimirPodolski · Sep 23, 2023

   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.
