Mattermost vs RocketChat: 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, RocketChat is detailed as "Open source slack alternative". Rocket.Chat is a Web Chat Server, developed in JavaScript, using the Meteor fullstack framework It is a great solution for communities and companies wanting to privately host their own chat service or for developers looking forward to build and evolve their own chat platforms..
Mattermost and RocketChat belong to "Group Chat & Notifications" category of the tech stack.
Some of the features offered by Mattermost are:
- All your team communication in one place, searchable and accessible anywhere
- Slack-compatible, not Slack-limited. Imports Slack channels, users and themes. Offers Slack-compatible webhooks and integrations including Hubot, Jenkins, GitLab and others
- Self-host ready with System Console and IT admin tools for managing dozens of team sites. Installs with Linux binary, plus Docker, Heroku, AWS, Azure and Cloud Foundry options
On the other hand, RocketChat provides the following key features:
- BYOS (bring your own server)
- Multiple Rooms
- Direct Messages
"Open source" is the primary reason why developers consider Mattermost over the competitors, whereas "Open source " was stated as the key factor in picking RocketChat.
Mattermost and RocketChat are both open source tools. RocketChat with 23.3K GitHub stars and 5K forks on GitHub appears to be more popular than Mattermost with 15.4K GitHub stars and 3.14K GitHub forks.
According to the StackShare community, Mattermost has a broader approval, being mentioned in 38 company stacks & 24 developers stacks; compared to RocketChat, which is listed in 34 company stacks and 12 developer stacks.
Mattermost sports higher performance, uses Postgres, is a pure server side application not using up too much of system resources on the client side, and gives an overall enterprise grade impression in general.
Updates go smooth without a hassle, everything is organised logically, and the integration with 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 in regard to introducing new features, but they maintain a stable experience, not breaking the codebase in order to hastily implement bells and whistles, which are not yet ready for production. Documentation and debugging are fantastic, so running this in enterprise production environment is absolutely approved of.
We chose RocketChat over other communications suites like Cliq or Slack mainly because we can self-host it on our own infrastructure. Since we have quite some projects going on which demand that we stay in touch with a lot of different stakeholders, pricing was an issue, too. With RocketChat, we have a huge set of features basically for free, RC offers apps for all major devices and systems and overall, we're very happy with it. The only downside is the limited amount of apps and integrations, but we can make due with what we have available.
