Mattermost vs Zulip: What are the differences?
Developers describe Mattermost as "Open-source, self-hosted, Slack alternative". Mattermost is modern communication from behind your firewall. On the other hand, Zulip is detailed as "Powerful open source team chat". Zulip is powerful, open source team chat that combines the immediacy of real-time chat with the productivity benefits of threaded conversations Zulip allows busy managers and others in meetings all day to participate in their teams chats..
Mattermost and Zulip can be categorized as "Group Chat & Notifications" tools.
"Open source" is the top reason why over 54 developers like Mattermost, while over 57 developers mention "Open source" as the leading cause for choosing Zulip.
Mattermost and Zulip are both open source tools. It seems that Mattermost with 15.4K GitHub stars and 3.14K forks on GitHub has more adoption than Zulip with 10.1K GitHub stars and 3.11K GitHub forks.
According to the StackShare community, Mattermost has a broader approval, being mentioned in 38 company stacks & 24 developers stacks; compared to Zulip, which is listed in 7 company stacks and 9 developer stacks.
Mattermost sports higher performance, uses Postgres, is a pure server side application not using uo too much resources on the client side and in general gives an overall enterprise grade impression.
Updates go smooth without a hassle, everything is logical, and the integration in the OS is absolutely stable. Apart from that, the underlying runtimes and code are mature, proven and stable.
The developers are maybe a bit more cautious regarding introducing new features, but they maintain a stable experience, not breaking the codebase in order to hastily implement new features, which are not yet ready for production. Documentation and debugging are fantastic, so running this in enterprise production environment is absolutely approved of.
We tried out a handful of communication tools including Slack, Microsoft Teams, and Google Hangouts Chat, before settling with Mattermost.
The customisability offered through your server's system console is unrivalled and in some ways overwhelming with the sheer amount of options that you're provided with.
All communication tools share 99% of their UI with each other, and Mattermost is no different, but that's not a bad thing. It also seems to have a less cluttered interface than the others we had tried, although I can't pinpoint the specific design choice that is the reason for this.
The fact that we can have control over all of our data (we're self-hosting it through AWS on a single EC2 instance) is also a great plus which none of the options that we looked into offered.
