Setup was smooth, server operation is transparent, user management trivial and everything just clicked into place when we were looking for a simple yet functional solution to team chat

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

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.

I really liked the platform. My team found it easy to learn how to use it. Now we are replacing email communications with Mattermost.

It's free, it's open source, it has very easy to follow documentation. It's safe and secure. It works smooth.

It could have sub-channels and addittional options to configure. Could give native option for audio sending.

Slack with AD integration at half the cost. But I still wish I could afford Slack.

Slack integrations just work on Mattermost. The theme choices are very nice. The ability to host my own on-premises server is very nice. Technical support staff is very knowledgeable and competent. I'm not made to feel like an idiot if there is some specialized knowledge that I don't have.

The Android client is extremely buggy and fairly slow still. Selecting a push notice to open Mattermost to view and respond in the thread does not always open the right thread and is always slow (even on LAN, with the latest gen of Android phone!)). The client MUST be snappy and it just.. isn't. The Windows client becomes slower and slower the longer you have it open, so it must be restarted every day or two. It's a little buggy; sometimes new messages make your view scroll up instead of down. But it works well enough most of the time.

I like that Mattermost not only offer instant messaging tools but also allocate web conferencing capabilities.

Searching keywords on chat doesn’t hide messages on private chats.

Screen sharing enhances large file sharing via drag and drop.Business instant messaging.

I like how Mattermost has a lot of features:- internal communication, screen sharing, web conferencing, business instant messaging and chat all in one place.

For nearly a decade now Mattermost has been a useful program, with no drawbacks in business matters.

File sharing, team collaboration, BIM and live chat.

Ever since I started using Mattermost, it has never been daunting to send large files online, collaborate via unlimited communication channels and manage projects automatically.

I do not like how Mattermost can’t function in absence of mobile data or WiFi.

Team management, internal communication and bug tracking are at par with this tool always.

Mattermost boost internal communication via creation of unlimited communications channels in one single repository.

I have been using Mattermost for an extended duration now and I rarely encounter challenges whenever I turn to it.

Mattermost boost productivity by unifying teams in my organization in one single workspace through corporate communication channels.

Video conferencing isn’t robust enough that’s why it demands to be integrated with external web conferencing systems like Zoom Meetings.

Real-time file sharing.Team collab.Business instant messaging.

Mattermost boost internal and external communication through creation of unlimited communication channels.

At the moment, Mattermost has no bugs and accomplishes all my daily needs.

Project management and business instant messaging.

Mattermost combines messaging and project management capabilities in one place.It has a robust backend integration feature, which boost it’s capabilities.Project coordination is another great thing about this tool.

I do not like that Mattermost demands to be integrated with external web conferencing apps to boost video conferencing.

We ended up looking for an alternative to Mattermost because of Slack's price-performance ratio and would switch again today.

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.

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)

I use mattermos mohr than one year, but still can not used to it. main reason is that when I get the new notification, I don't get some signal, or beep. it doesn't appears on screen. mattermost is in my company main communication system. if I would asked, I would changed it with skype for business, or lync

mattermost is our companies inside network. we use it everyday to communicate. I like it because I have it also in my mobile. now when I work remotely, i am not always nearby computer and with mattermost I am always in touch.

A super and ready to use Slack alternative.

* The replacement of slack * Mattermost has almost the same features as Slack * You can host and run your own instance on your own server (For companies which hate clouds) :) * You have a good overview of logs and you can see what goes around * The statistics gives a good point when a dev team is productive * You can easily create unlimited integrations which some internal stuff

* The lack of integrations (Slack is here over the top) * The incoming hook limitation of maximum content length is the hell (Mattermost don't inform the customer about a message which was higher above the hard coded message size limit) * UX in Slack is a little bit better (Slack is massively using websockets and eventstreams to fetch the actual team messages) -> You see always whats going on * A 'Unread' channel (like in slack) would be a pleasure ;) * A step by step guide for creating an integration would not bad for not advanced users

Very good. Prefer it to slack as it can be self hosted

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

Needs Manual intervention to clean up old files

Mattermost is a great software to use with the virtual employee situation which allows the sharing of ideas, answers to customer facing issues, and the ability to communicate privately with leadership and/ or teammates. The chat is instantaneous, which allows for faster responses than emails.

Interactive media that allows instant communication with teammates and leadership, whether it was a question or just sharing of daily life. The ability to host channels that was based on teams, programs, and specified topics. All individuals were able to have private groups to chat with friends, co workers, or teams.

The scroll in chats often moved so very quickly that questions and responses were missed. Inability to customize responses such as color, fonts, etc.

tool is great, and from this users perspective is a fine alternative to slack.

It's very easy to use, and as far as I can tell works alot like slack. I'm not sure if it has as many plug-in options but that's not something I'd use anyway. Great for team collaboration and general communication.

I get LONG LISTS of rooms and chats and there is no easy way to search for people aside fom doing a control-f. I can search within chats, but I think it needs to be easier to search FOR chats

We are very heavy into enterprise chat. We are not allowed to use off-premise (i.e. cloud) hosted solutions for security reasons. When Atlassian decided to sell Hipchat to Slack, that put is in a bit of a bind as Hipchat was essential to our business communication process. With the implementation of Mattermost, I am actually finding that my staff prefer Mattermost to Hipchat.

I did an evaluation for a replacement for our Hipchat server as Atlassian is phasing out Hipchat for on-site chat. In doing a direct shootout between Mattermost and a competitor, I found Mattermost much easier to install and administer. Mattermost's team has been very responsive in the evaluation process. There are a large number of plugins available to connect other development tools to Mattermost. It's clear it's a product that is getting actively maintained, with new features and functionality coming nicely down the pipeline to the end users.

The Jira integration is currently not as fully-featured as Hipchat's was. That said, I believe that a better integration is coming down the pipeline. The default video chat/screen share plugin is Zoom. I would prefer having other options.

overall it simplifies ma daily activities. and it seems it's useful for me.

i like that i can reach easily all employees and communicate with them. i like numerous of stickers and smiles and ability to make group chats.

it isn't easy to use. when i receive message sometimes i miss notifications. when i click pop up window it doesn't begin conversation, i have to find message in contact list. this is inconvenience.

Matter most lets you own your own data. Self-host Mattermost means not letting a third-party control what actually matters in a chat open. The open dvevelopment model gives insight into the upcoming relase cycle, see if others have solved integration issues that you may be attempting, file bug reports and follow the progress in fixing or even contributing a fix back yourself.

Mattermost still has some rough edges regarding their mobile clients. The new native app is definitely better than the previous web-view one though.

despite it being little more harder to use, it's more enjoyable sometimes all you need after hard day at work is funny co worker sending some hilarious gif.

the main think i like in Mattermost is design it feels lighter, it makes me feel happy, emojis are great way to impress and make communication more informal, also ability to use gifs is one of most useful features

compared to other communicators i used it feels little bit harder to use, its easy nothing very difficult but it feels like i need some extra effort to find person and use direct messaging.

Mattermost is my go-to tool when you want to discuss something with colleagues. Ability to create public/private channels and send private messages both work nice and easy.

No so great for file sharing and doesn't work as a discussion tool outside your organisation.

Better team communication, improved efficiency, new communication channel

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

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

Opensource alternative to Mattermost. Allows team communication on one place, especially for things that should be in chat-groups-discussions and not in countless emails that are hard to track in multi-user environment.

It is opensource, it has no limits like Slack and it allows similar experience/functions. It is not easy to set-up but once started it works with no issues on desktops/laptops.

Android app is not connecting to some servers (all I built). SSL certificate handling is a bit tricky. Default way of creating users is sending them link (creating user/pass would be a good option).

It's a good workspace platform for people who remote work and for me it helps communicate many work-related things easily.

a. Simple workspace platform, especially for remote workers b. Many integrations can be made and compatible with Mattermost c. Highly customizable due to its open-source based.

d. UI is not really appealing. The UI theme kind of always remembers me that I'm working. It's not necessarily a bad thing but it could be less "work-theme", so we could feel a little bit relax. e. Cannot make a thread out of a message.
