Considered Multiple Products
Mattermost
Chose Mattermost
Slack got very expensive and limited for the use we expected and also for the economic resources of the company. Mattermost allows custom modifications, and its interface is very similar to Slack, so we didn't need much time to adapt to it. We've been using Mattermost for 3 …
Chose Mattermost
Mattermost is very comparable to Slack. While Slack is more well-known and has a larger budget for advertising, Mattermost can hold its own. Slack probably has some additional integrations, but for what we were looking for (a quality communication tool) Mattermost was a great …
Chose Mattermost
Slack is excellent and has many of the same features as Mattermost. However, the cost if you have a larger group can be prohibitive. Mattermost is a better ROI per user, in our opinion. It also allows us to host it ourselves, which is more desirable for management by our MIS …
Chose Mattermost
As compare to Slack with this tool, Mattermost has introduced more convenience and features for collaboration. All updates come with new and advanced features and functions which always fascinate me and become the reason for using this efficient tool.
Chose Mattermost
We selected mattermost since we can control storage of our data. Slack is a great tool and offers more robust features compared to mattermost. However, the previously mentioned reason & the competitive pricing allowed us to stick with mattermost.
Chose Mattermost
Microsoft Teams feels quite clunky and the video chat is buggy. Slack is close but maybe not quite as feature-rich. Mattermost just feels like the right tool for a company my size ~1000+ users. No one has had any major issues with this tool and there haven't been any …
Chose Mattermost
Mattermost is very similar to Slack and has the advantage (in our case) of being entirely on-premises, and entirely free. The feature set is similar, and it has filled the original need that Slack was suggested as a solution for very well. Teams is potentially a better choice …
Chose Mattermost
Honestly iv just used these two but when it comes to customization, they don't come close to Mattermost. Slack and Teams are Less flexible, Not self hosted. Not Open source,etc I will also say that i noticed integration capabilities are very limited with teams and Slack and not …
Chose Mattermost
Slack is by far my personal favorite due to the age of the platform and the maturity of the features. Mattermost is a close 2nd-
Chose Mattermost
Unlike Slack and Discord, Mattermost is self-hosted and focused on security. I used Discord before for community management and much simpler and less secure operations. Slack is great, but the fact that is cloud based takes out a lot of its independence.
Chose Mattermost
In comparison to Slack, where Slack is strictly for internal communication, Mattermost actually has the format to display and not alter source code. Google Chat is also even more limited in comparison to Slack and Mattermost. If you collaborate on code every single day, then …
Chose Mattermost
They're very similar. I think it's really a matter of preference. Again, one of the things I like about Mattermost is that it's strictly for business (atleast for us) it's different from the more mainstream messaging apps used so we can kind of separate work vs personal messages.
Chose Mattermost
Much more expensive than most chat applications but you have more control over things by self-hosting. Your security team will be able to design a very secure place to store all your code, passwords, and internal details, but most companies will not require this. It would be …
Chose Mattermost
These products all required cloud connectivity and licensing that was a significant cost. Mattermost allowed us to pilot this among just the Ops team and then evangelize this to the other infrastructure team. This allowed us to slowly show the value of this software and expand …
Chose Mattermost
to reduce cost we shifted to Mattermost.
Chose Mattermost
Mattermost works better in that there aren’t constant updates and changes which can make finding past messages difficult. Mattermost also works better for channel creation and communication
Chose Mattermost
Mattermost provides a familiar user interface, fast performance, and a complete set of user collaboration tools and features - it stands out by providing a self-managed installation option for better integration with existing IT assets and more control over data storage. We …
Chose Mattermost
key selling points for us was that its open source and can be self hosted.
Chose Mattermost
First of all, we don't lose messages; we can see or search messages from any point in the past. Second, it offers to manage the whole product ourselves from hosting to serving users of our organisation. We feel that we have full control over data, managing users, …
Chose Mattermost
Skype is a light version when compared to Mattermost. Skype is easy to login (using username and password). Whereas, Mattermost login or setup or configuration is way different from Skype. We wanted to integrate with Jumpcloud for various reasons, so we have selected Mattermost …

Slack
Chose Slack
Much simpler and more pleasant to use than the alternatives.
Provides integrations, with external services, that work out of the box which is often an Achilles heel of competitive solutions.
Pricing is unfortunately not that great when compared to alternatives that come in a …
Chose Slack
The most convenient way to organize and follow thread (so any conversation) and a very large way to customize the workspace by individual (my workspace is organize in my way, but my colleague can have their own structure and organization). Also being able to add customized …
Chose Slack
Good User interface, feels easy to use
Easy to open a thread and have a discussion with rich text editing
Integrations are good, helps to check the status of many entities from single place

I used Mattermost on a full remote company and it perfectly suited our collaboration and communication culture. The company dealt with privileged and personal information of a huge data base of users, so it was a significant advantage for our need to comply with industry regulations.

Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

Slack suites well for multiple scenarios. (1) table stacks 1-1 and group conversations. (2) Level of integrations with external systems like, Confluence, Google Docs, JIRA, etc. (3) Nice integration with Claude allows lots of automation possible. (4) Allows external people (outside the company) to participate. This is great for direct customer interactions.

Pros
Mattermost
  • Easy intergration to our main CRM (Monday.com)
  • I'm not techy myself but I have seen a lot of our previous integrations in Slack transferred over to Mattermost so that's fun
  • The desktop and phone app (android) works well enough. I haven't tried it on the Apple ecosystem yet.

Cons
Mattermost
  • Some of the features in paid plans could be free, however, they have much offered in free plan (self-hosted)
  • The Desktop App we use on windows has some bugs, like when Mattermost is down and comes back up, the app needs restart

  • Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
  • Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

Slack has good usability. Devs that are not familiar with the platform are able to jump into conversations and start sharing code and links within just minutes. Non developers are also able to understand the layout such as the Project Managers that are keeping the projects on track. We have not seen any tickets where employees are having trouble understanding Slack.

Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

I feel slack is a bit more difficult to use overall than Mattermost. Mattermost makes the tasks of communicating across departments and team members easier, as well as giving the ability to share information via hyper links, attachments, and other forms of communication among every body here. Also, easier user interface

Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.
