What is Mattermost?
Mattermost is a secure, open source platform for communication, collaboration, and workflow orchestration across tools and teams.
As an alternative to proprietary SaaS messaging, Mattermost brings all your team communication into one place, making it searchable and accessible anywhere. It’s written in Golang and React and runs as a production-ready Linux binary under an MIT license with either MySQL or Postgres.
Mattermost is:
Slack-compatible, not Slack-limited – Mattermost features rival Slack features, and support a superset of Slack’s incoming and outgoing webhook integrations, including compatibility with existing Slack integrations. From your existing Slack teams, you can import users, public channel history and even theme setting colors into Mattermost.
Mobile and desktop apps, in addition to web – Use Mattermost from your iOS or Android phones and tablets or with installed apps on Windows, Linux and Mac.
Easy to deploy, manage, and upgrade – Mattermost runs as Linux binary, Docker image, and many other forms. Try Mattermost with a one-line Docker install, and many install guides are available. Improvements ship monthly.
Supported by a vibrant community – Use Mattermost with dozens of community integrations and applications, including Jira, IRC, XMPP, Hubot, Giphy, Jenkins, GitLab, Trac, Redmine, SVN, RSS/Atom and many others. Build and share your own apps using Mattermost APIs and drivers.







Comments and Reviews
GitLab officially integrates Mattermost in its deployment packages. Providing a single sign-on for users of both applications. http://docs.gitlab.com/omnibus/gitlab-mattermost/
Open source slack knock off. Slack already sucks, this sucks even more, though at least it's more open.
There's no good Linux client. Of the only ones that are actually usable one was a bloated electron monstrosity, the other wants access to create a second account on their own server and feed all your instant messages to them. Lol! Needless to say I ended up using the first one.
All this program is, is a glorified chatroom. IRC does the same thing a million times better, without the onerous account system and the pathetic selection of clients. The chat interface itself is a mess, cluttered with things like dates, needless separators, ugly icons and emojis. One of their "features" is that you can put emojis on people's chat messages, like in Github images. Who the hell needs to pin emojis on chats? Just reply with the emoji if you really have to.
Godawful program, but unfortunately your boss will require to use it. Oh well, at least it's not slack...
Mattermost is more developer-friendly than Slack (or at least, when compared to "new Slack", which seems to have gone down the rich text editor route rather than staying true to markdown).
Trying to post a review ...last one ended up in "comments" section as double post
I would not advise to install it - !!! Software is too simple no image display , no nothing ...but what it does have is a tracking if you try to remove it - server wont start - coz its always connecting to a third party sites:
cdn.rudderlabs.com cdn.segment.com/analytics.js
Avoid this software !!!
DO NOT INSTALL THIS SOFTWARE !!! It has tracking build in - and if disabled - chat server wont start
check who they are working with btw :)
right :) ...
Does not support voice (or video for that matter) calls natively; you need a third-party plugin for that. I guess it supports it somehow?
A quick tip: If you like to test and use Mattermost instantly, install it for free as a ready-to-use virtual machine image via Univention's App Catalog. This image contains the app itself and a UCS runtime environment. Apart from being quickly installed and free, you also get regular updates for the whole stack.
