Does anyone have an insight into the differences between Slack, Mattermost, and Gitter? I have only ever used Slack before but it seems like Gitlab is already heavily invested with Mattermost. That makes me wonder what the future looks like for both Mattermost and Gitter. Are they different enough that they can both coexist without hurting either product or is one of them destined to be folded into the other in hopes of taking on Slack more directly?
Gitter is targeted at providing a public channel around a project, Mattermost is more Slack-like for team-internal organisation (with multiple channels, user management etc)
Thanks - haven't heard of Gitter, came to the comments to ask about the potential impact to Mattermost. Sounds like there's room for these two to coexist within GitLab.
We chose gitter over slack as an open core company. I close leads, hire engineers, and run our team chat all on one platform. (We supplement this with hangouts) . The idea that all of my activity and communications can happen on one platform is pretty appealing. We also don't need many features (aside from better search please!)
