Zulip Chat vs Mattermost Review : Which Open Source Chat Server is Better

Tanuja Chinthagunta

In 2016, Uber made an unexpected move and left Slack for Mattermost. 

The ridesharing company needed an enterprise-grade collaboration tool which Slack couldn’t provide. Hence, Uber decided to create its messaging solution on Mattermost. 

In 2017, both Uber and Mattermost joined hands to implement an upgrade of Mattermost platform, and it eventually met Uber’s need for an uber team communication application. 

Uber’s Shift from Slack makes one question its status as ‘the pioneer of collaboration tools’ and also look for leading alternatives like MatterMost. 

Facing a similar issue of asynchronous chat management, Akamai – the world’s leading content delivery network service provider – was also looking for a better alternative to HipChat, Slack, and Microsoft teams until they tried Zulip.
Akamai’s search for a perfect application for their organization ended with ‘Zulip’ because of its exclusive ‘threading features,’ which was a massive win for a large organization like Akamai.

Uber and Akamai’s Shift to Mattermost and Zulip are the testimony to the fact that they both are the next-gen team communication application – yet to be exploited by the masses, but promising enough to make one anticipate of the uber-cool features that will make communication easy and collaboration too much fun!


Disclaimer: We are moving Troop Messenger to self-hosted for larger enterprise and government corporations. Since there are so many self-hosted chats applications out there, we’ve started this to perform an in-depth analysis of our competitors with their pros and cons from a customer’s perspective and tried to come up with a better, cleaner and more user-friendly chat alternative. We have an entire article with the results of competitors’ research, covering our feedback on various alternatives. However, this time we would like to focus on two rivals: the well-known Zulip and Mattermost.

Zulip and Mattermost: NextGen Team Chat applications


Zulip is an emerging leader of business collaboration tools. Known for its killer email threading model, Zulip assures its user to efficiently catch up on the important notifications and conversations while muting the irrelevant ones. Zulip has made a mark among great many collaboration applications and known for providing the advantages of real-time chat. No other application is known for handling synchronous and asynchronous communication as intuitively as Zulip does.


Mattermost, as open-source messaging software, has earned the trust of millions of users. Not only does it allow the users to create an intuitive workspace but also collaborate across teams without worrying about data privacy or security. A great number of high-security enterprises have been working through Mattermost by connecting their team and deploying automation for maximum benefit.

Why are we comparing Mattermost with Zulip? 

There are plenty of team communication and collaboration apps. And Slack is already ruling the charts. It’s apparent for readers to wonder why we are discussing Mattermost and Zulip when there are bosses like Slack, HipChat, Skype and RocketChat.


Every organisation is different in terms of functionality, collaboration requirements, team engagement. ‘One Size fits all’ is a myth and definitely not applicable to business collaboration requirements.


People today need greater choice, and that is where the one-size-fits-all approach comes to an end.


Slack and other similar tools of the same calibre are indeed great but they lack certain specific features that can be accomplished through employing either Zulip or Mattermost.


Hence, there’s an imminent need to try out different tools, compare their features, understand how they can be utilised to their full potential, and find the one that fits your business requirements to the fullest.
