What is Mattermost?
Mattermost serves as a self-contained collaboration platform, providing tools for chat, workflow automation, voice calling, screen sharing, and AI integration. Its code licensing under the AGPL is somewhat unclear and does not completely align with the Open Source Definition.
As an open-source alternative to proprietary SaaS messaging platforms, Mattermost consolidates team communication into a single, searchable, and universally accessible location. It is developed using Golang and React and operates as a production-grade Linux binary under an MIT license, compatible with both MySQL and Postgres databases.
Mattermost is compatible with Slack but not limited to its features. It matches and expands on Slack's capabilities, supporting a broader range of incoming and outgoing webhook integrations, including compatibility with pre-existing Slack integrations. Users can import data from existing Slack teams, including users, public channel history, and theme setting colors. Mattermost can be accessed through iOS or Android mobile devices, desktop apps on Windows, Linux, and Mac, in addition to its web version. It is designed for easy deployment, management, and upgrading, running as a Linux binary, Docker image, among other formats. A vibrant community supports Mattermost, offering numerous community integrations and applications, such as Jira, IRC, XMPP, Hubot, Giphy, Jenkins, GitLab, Trac, Redmine, SVN, RSS/Atom and more. Users can also develop and share their 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/
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 !!!
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).
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?
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...
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.
