Gitter vs Mattermost: What are the differences?
Gitter: Messaging for people who make software. Integrated with your team, projects and your code. Free chat rooms for your public repositories A bit like IRC only smarter. Chats for private repositories as well as organisations.; Mattermost: Open-source, self-hosted, Slack alternative. Mattermost is modern communication from behind your firewall.
Gitter and Mattermost can be categorized as "Group Chat & Notifications" tools.
Some of the features offered by Gitter are:
- Know who's seen any message
- Edit messages after you've sent them
- Full emoji support
On the other hand, Mattermost provides the following key features:
- 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
"Github integration" is the primary reason why developers consider Gitter over the competitors, whereas "Open source" was stated as the key factor in picking Mattermost.
Mattermost is an open source tool with 14.9K GitHub stars and 3.04K GitHub forks. Here's a link to Mattermost's open source repository on GitHub.
According to the StackShare community, Gitter has a broader approval, being mentioned in 25 company stacks & 41 developers stacks; compared to Mattermost, which is listed in 38 company stacks and 24 developer stacks.
From a StackShare Community member: “We’re about to start a chat group for our open source project (over 5K stars on GitHub) so we can let our community collaborate more closely. The obvious choice would be Slack (k8s and a ton of major projects use it), but we’ve seen Gitter (webpack uses it) for a lot of open source projects, Discord (Vue.js moved to them), and as of late I’m seeing Spectrum more and more often. Does anyone have experience with these or other alternatives? Is it even worth assessing all these options, or should we just go with Slack? Some things that are important to us: free, all the regular integrations (GitHub, Heroku, etc), mobile & desktop apps, and open source is of course a plus."
We use Slack to increase productivity by simplifying communication and putting Slack in the middle of our communication workflow #Communications #Collaboration
We use Discord to tracking some action and errors (logs / alerting / assertion). it's free and simple to use with mobile application et notifications
We use Slack because we can let "tools talk to us" and automate processes in our dev team using bots.
Our Discord Server is our n°1 community stop; we gather feedback from our users from here, discuss about new features, announce new releases, and so on.
We even use it for internal meetings and calls !
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.
