Mattermost vs Slack: What are the differences?
What is Mattermost? Open-source, self-hosted, Slack alternative. Mattermost is modern communication from behind your firewall.
What is Slack? Bring all your communication together in one place. Imagine all your team communication in one place, instantly searchable, available wherever you go. That’s Slack. All your messages. All your files. And everything from Twitter, Dropbox, Google Docs, Asana, Trello, GitHub and dozens of other services. All together.
Mattermost and Slack can be categorized as "Group Chat & Notifications" tools.
Some of the features offered by Mattermost are:
- 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
On the other hand, Slack provides the following key features:
- Create open channels for the projects, groups and topics that the whole team shares.
- Search with context
- Autocomplete makes mentioning your teammates quick and painless.
"Open source" is the primary reason why developers consider Mattermost over the competitors, whereas "Easy to integrate with" was stated as the key factor in picking Slack.
Mattermost is an open source tool with 15.4K GitHub stars and 3.14K GitHub forks. Here's a link to Mattermost's open source repository on GitHub.
According to the StackShare community, Slack has a broader approval, being mentioned in 4795 company stacks & 3481 developers stacks; compared to Mattermost, which is listed in 38 company stacks and 24 developer stacks.
I still use slack, although I prefer discord. It can be intergrated with discord to work with clients who only want to use slack or even any other platform. API integrations are possible over at Discord.
The awful crappy dependency hell of a thing they call an API. Everything sucks. Slack is one of the worst messaging apps I have ever seen. It's incredibly slow and laggy.
Let me rant about everything I hate about slack. Even though I use it as an integration for another platform and will recommend it even though it's horrible as a whole. They are unstoppable towards companies who don't have people technically savvy enough to transition any other software.
It's so bad I am considering making my own mix of discord and slack.
Finding conversations you know you've had - but search is (Still) terrible, and if it was a direct message with a group of people, you have to remember exactly which group of people it was with
Search...absolutely awful. If they could figure out search, Slack would be unstoppable. it got better with ctrl f in conversations, but still isn't there
Badly arranged Chinese buffet of people, conversations, channels, files and links.. and search sucks too.. Break up the people into a separate window so I can have a buddy list ala Communicator or Skype. Give me some freaking organization and curation to the conversations - otherwise it's 1000 person cocktail party with everyone playing drinking games.
AGAIN! Search sucks. Spellcheck is still broken. Too many notifications.
Interface ist inconsistent between devices.
No way to forbid slack to touch my microphone settings (seriously, dont autoadjust my microphone level, it never works and i hate you so much for it)
Still no good screen sharing on linux.
The buggy red dot. Usually shift-esc will clear it (in itself a pain), but now even that hack won't help. The red dot number keep climbing even though I've read everything and used shift-esc.
I miss some features but I wish slack had a little more ability to organize, group channels, and navigate a little better.
user groups need work... If I search for a group, open it, I want to be able to not just see who is online from that group, but also a message button. I'm sick of searching that person, which closes user groups and if that person is actually AFK, I have to search for that group AGAIN and do it again... What a waste of time compared to other tools which are supporting this.
Date stamps needs to be more visible, or give us option in settings to make it more/less visible
Scrolling needs to be improved, I don't want random jumps there. Especially when time and date stamps are so tiny so it takes a while to get oriented again.
I used to really hate slack, but that's mostly because I have to use user groups a lot, most of the time I'm using slack it's to find someone who belongs to some group and message him... and that stuff is still pretty bad, even tho it was changed a bit...
oh and microphone settings... that hurts bad...
It's slow and laggy if you ever used a native program and got used to responsive user interfaces.
You can't remove someone from a call if they join by mistake
(or, to put it another way, if you start a channel call, you should be able to moderate it and remove those from it who are to meant to be there)
Video calls (using the "native" app on macOS) consume so much resources that the whole machine becomes unresponsive. A video call with the same number of people in a true native app is not a problem. So it's not the inherent bandwidth and processing power required. I mostly like Slack but for remote teams this is a problem.
You really want to know what I hate about SLACK...
The inability for the app to BLOCK DIRECT MESSAGING when outside work hours... I work for global company and I constantly get messaged after midnight by morons who think i am up at 3am
It has this Bullcrap Send Anyway function on messages which totally overrides my Do Not Disturb settings if said moron is blind of what time they are sending their damn message... I worked oncall before so the slightest him of my cell at night will wake me up...
Another annoyance on messaging... Idiots who message direct over chatting in the team channel for stuff that should be seen by the whole team working a ticket .... Or classic hey I opened a ticket not two minutes ago ' can someone look at this ticket pleaee' blah blah blah blah ... People who I don't know sending a random 'HI' and no other info about wtfh they are reaching out to me about ...
If SLACK wants to add a function to fix this I want control to block direct messages from anyone truly outside my direct team and line of management that is not a member of a group that can engage onCalls for issues ... I am so sick and tired of this I literally have to uninstall the app everyday to ensure no one bothers me after I am off work and then redownload it before the start of the next day... It's pathetic!
As it is the communication tool chosen for the course, our team will be using Slack to monitor the course announcements from our instructor as well as to communicate with the instructor and industry partners. The tool for communicating within the team will be Microsoft Teams. Microsoft Teams enables the team to share documents and edit them synchronously(Google Drive is not an option due to one team member's location). Since it also provides a group chat feature, we chose to use it as our communication tool to avoid using too many softwares.
Communication We have chosen two tools for our team communication.
We choose Slack since all of us are familiar with this communication tool. We have a private channel for our team Sphinx for text messages. We added Github apps inside our private channel for repo update notifications. Furthermore, we could contact the subject matter experts within the workspace DCSIL directly for the issues we meet.
- Microsoft Teams
We use Microsoft Teams for virtual meetings for its fast connection speed. In addition, the call feature in Slack is a paid feature, and we could have virtual meetings and share screens for free in Microsoft Teams.
