Mattermost is an open source enterprise messaging and team collaboration application. It’s like Slack, but with excellent Markdown support. In fact, Mattermost provides exactly the type of Markdown support you want to see in a messaging application. You can type messages in Markdown or copy and paste Markdown-formatted text into the message field — it works exactly the way you’d expect it to.
