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
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.

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.

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 …

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.

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 …

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 …

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.

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 …
