Mattermost

Vorteile

Running on a VPS, the free version is super cheap for unlimited users. Supports all major client platforms including browser.

Nachteile

Updates can be a probem, and sometimes user's options for 'auto update check' and 'system tray color' seem to get lost.

Slack

Warum Mattermost gewählt wurde

Teams became difficult to manage in our secured environment. Recently (early 2025) Microsoft cloud has had numerous issues which do NOT affect out MatterMost setup.

Vorteile

Mattermost unify teams in one place through unlimited communication channels in one place.

Nachteile

Video conferencing capability requires to be merged with external web conferencing tools to make it robust.

Vorteile

Mattermost unify teams in one place through unlimited communication channels.

Nachteile

I slightly dislike that Mattermost demands to be integrated with external web conferencing app to enhance video calling.

Vorteile

Mattermost offers robust business instant messaging and live chat capabilities which allows us (teams) to seamlessly collaborate in real-time.

Nachteile

Unavailability of builtin video conferencing capability is the only flaw but I have integrated with external web conferencing applications.

Vorteile

Mattermost is constantly being developed and you can tell that it's going further. In addition, as a collaboration tool, it provides the most important information. No more and no less.

Nachteile

At the beginning (approx. 2018) it was still a bit unstable and some important features were still missing. This has gotten much better in 2022. Over the years, with many users, maintenance and upkeep should never be neglected. Otherwise it will be slow and have long loading times when changing channels etc.
Plugins work, but not all are mature (e.g. Jitsi caused problems for us)

Vorteile

Self Hosted, easy to use and implement on our own servers.

Nachteile

Needs Manual intervention to clean up old files

Gründe für den Wechsel zu Mattermost

Self Hosted, Nice UI

Vorteile

I like that Mattermost has all the tools that allows us (teams) to coordinate on projects via creation of unlimited communication channels.

Nachteile

Video conferencing capability requires to be integrated with external web conferencing tools.

Vorteile

Mattermost was absolutely trivial to set up and maintain, which was a huge plus back during the first dawn of Covid where we struggled to find a solution to team chat that allowed us to host on-premise, keeping all our data local - a must for many projects which have complicated data privacy regulations that are a nightmare to work around with cloud based products

Nachteile

One of the paid feature is unlimited search, and as a free user (10,000 line search limit, I think), it is often unclear whether you can't find what you're looking for because you hit the limit or because it's just not there.

Vorteile

Main features for us: easy use, on site option, boards and channels and easy API

Nachteile

I would like Mattermost has better video and call options

Vorteile

The interface is pretty much self-explanatory. This is why the user acceptance is quite good. Customizing the interface is straight forward and can be done at user level.
The open source cummunity around Mattermost is really nice and welcoming.
Apps for every operating systems are available and easy to use once manually set up.
Scalability was never a problem with 1000+ users.

Nachteile

Setting up integrations is more complex than with Slack, where integrations can be installed with one click in the backend. There is an app directory, but the apps need to be set up manually. Once set up, they just work. Incoming webhooks are the only exception; they work out of the box.
Mobile perfomance is gradually getting better, but it's not yet up to Slack's par.
The Windows-app is not yet ready for big scale rollouts via group policies.

Vorteile

easy to use
S3 backend
Good support of different databases
Quite easy to configure for the different needs of a company
I love the threaded reply, make it so much easier to follow multiple threads in the same channel.
Mobile notifications are quite useful
Mobile native app was quite welcomed, the previous one wasn't up to standard

Nachteile

some glitch in the mobile applications
Weird marketing decisions on which feature goes in which package
Can't see how many private channels are present (as the administrator of the server)

Vorteile

Mattermost is customizable and fairly simple to use. There’s essentially no learning curve as it has all the familiar landmarks of instant messaging. I love the ability to create customer emojis which my office lovingly partakes in. It allows us to work efficiently and quietly, while being able to communicate seamlessly between departments. The interface looks clean, and I can’t think of any glitches to date on the web application version.

Nachteile

I would like a better search feature, and perhaps the ability to search by person rather than just chronological. I use both the web app and the mobile app, and the mobile app can occasionally force quit and delays messages now and then.

Vorteile

There are not that many good options for team messaging apps.
Hipchat or Microsoft Teams do not even come close in terms of either functionality or scalability from a slack.
Hipchat,Yammer, Skype were from another generation.
However slack is expensive, and they limit your search history, if you're using their free version.

Mattermost has the exact same functionalities but its code base is totally open so it can be integrated with anything you can think of (even those legacy applications that Slack won't bother with).

Nachteile

Might take you an hour to deploy.
and if you're not familiar with deploying applications you might have to read the instructions...
But other than that. It's a 10/10.

Vorteile

Mattermost has made communication feasible for our distributed team. Direct messages, private and public channels provide everything we need for different types of messaging.

Nachteile

The UI isn't as smooth as the one you'll find on Slack, but general features and functionality are all there.

Vorteile

What I like the most about this collaboration software is the simple and logical UI, which is not overloaded with lots of unnecessary features. It has all we need for successful communication. Also, it's very easy to deploy and integrate. Ensures really secure collaboration.

Nachteile

Great tool overall, perfectly performs its functions, didn't face any issues or drawbacks. Highly recommend.

Slack

Vorteile

When it's too much to send an email or you can't be bothered to get out of your chair, Mattermost is perfect. It allows all our staff to quickly chat about things without clogging up inboxes or having them on their phones. Groups and channels are great, especially for management needs.

Nachteile

The ability to preview non-image files would be nice, some files,​ have to be downloaded to be previewed.

Vorteile

I like the interface and how you are able to customize it

Nachteile

I think the search bar sometimes is not efficient

Vorteile

I always prefer to use open source software where possible. Mattermost was a great option to have in the running with the likes of HipChat and Slack. The community was great and it was easy to contribute.

Nachteile

The mobile experience didn't seem quite as polished as other collaboration software at the time, it's possible that this aspect has improved recently.

Vorteile

Mattermost was really easy to setup, the additonal https configurations are also well documented. As for the user side,it is similar to slack

Nachteile

Single Sign On functionality is based on plugin, which sometimes doesn't work that well. Other than that,no problems performance or functionality-wise.

Vorteile

El chat, es muy fácil la comunicación interna entre departamentos lo que me facilita presupuestar diferentes partidas antes de dar precio al cliente

Nachteile

De momento nada, estamos valorando las opciones

Vorteile

New features coming without increasing complexity for the user, the open source DNA, it's capacity to integrate anywhere.

Nachteile

The mobile app could be faster, and I miss the capacity to paste easily something with more than 4000 characters.

Vorteile

It has the PlayBook plug in right off the bat. Playbook helps assign various tasks in case of disaster and keeps a log of whatever is done and sent, so collaboration is good.

Nachteile

Not customizable enough, even if we speak for color schemes. My other team likes darker tones for the midnight shifts and it`s not to say that the deep blue is bad, but it`s not as comforting to know that you don`t have much of an option to choose from.

Vorteile

Just Works, Really cool for improved communication between team and clients.

Nachteile

A little expensive if they had an inexpensive community version I would gladly contribute some money to them. As it is am forced to use without contributing due to a high barrier to entry.

Vorteile

I like that this gives you the ability to speak with people both inside and outside your organization

Nachteile

I have compatibility issues and am not able to use the app on my phone

Vorteile

That's a nice alternative to Slack. Managing channels and using the entire product is very easy and intuitive.

Nachteile

Mattermost is so similar to slack that I don't even expect other functionalities. You can treat it like the same product.

Vorteile

It is a decent platform to communicate for group projects. I use this weekly for a project involving 20 members.

Nachteile

This software crashes very often whenever I use it. This program takes forever to open, I'm not sure if it is just my computer or not.

Vorteile

Its a free chat program that allows for a lot features. You can create private chats or group chats and lock it down to only the admin team or a company wide chat group. You can send docs and other files with it.

Nachteile

Its kinda blah... boring. It basic txt apps with gifs.
