Why move from Mattermost to Slack?
Better Cloud Experience
With Slack's fully managed, cloud-based platform, you don’t have to worry about server maintenance or hosting, unlike Mattermost’s self-hosted model.
Superior Mobile Experience
Slack provides a more consistent and user-friendly mobile app experience, making it easier to stay connected on the go compared to Mattermost’s mobile options.
Rich Media Support
Slack allows for smooth sharing of rich media like images, GIFs, and videos, making it a more visually engaging platform for team communication compared to Mattermost, which can be less media-friendly.
