Mattermost

Software developers are big enthusiasts of a ChatOps software, such as Mattermost, as it allows for direct collaboration without unnecessarily relying on email to get projects done. That goes for any teams that require collaboration. Some scenarios where Mattermost may not work as well would be teams that are in different geographic locations, such as teammates in India. Due to the time difference, collaboration would be harder, and an application like Mattermost may not have that much benefit.

It's very easy to use. Only at the point of configuring it will ask for some details. Apart from that, it is going to be a smooth process for anyone who wants to use this as their communication service. I am totally comfortable with using it in our organization

Direct support is only available for the paid version, but there is a very active community that provides a considerable amount of information.

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 department.
