Mattermost Likes & Dislikes

Mattermost offers room for the creation of an unlimited number of communication channels under one roof. I like how Mattermost streamlines internal and external collaboration via instant messaging and live chat.

this tool is easy to use, immediate, the interface is nice and enables you to also use emoticons in your status to make your job more friendly .

Mattermost enables me to create unlimited communication channels in one spot. Additionally, Mattermost supports large file sharing and has a robust backend integration capability.

Unavailability of built-in video conferencing capabilities forces me to integrate MM with external web conferencing platforms.

I think other competitors give you more usage chances, such as the possibility to plan and host calls in the platform, and the chance to use an integrated sharepoint

I slightly dislike that Mattermost requires an external web conferencing application integration to conduct video calls.
