Mattermost is an open-source Slack alternative for team communication. It's built by YC alums SpinPunch. You can host Mattermost on your own servers, and build whatever new functionality you want atop the code base.

I like the idea of an Open Source Slack but I'm not sure I understand. Mattermost has the same UI and UX (also the same font, from what I can see on the screenshots) as Slack.
