I signed up for this looking for a self-hosted Slack alternative, but it turned out to be sub-par and something I didn't want to commit to. Then I got an email from them deleting my workspace without explanation. Pretty funny.

Mattermost is a breeze to install, configure and run. No flakiness, dependencies or arcane error messages. That's gives confidence to to run it.
