Mattermost is a sleek, Slack-compatible open source service that makes it easy to self-host team communications. It brings messaging and file sharing into one place, accessible across PCs and mobile, with archiving and search. It integrates with a range of apps out-of-the-box and is extendable so you can build custom functionality on top of the Golang / React core.
This appliance includes all the standard features in TurnKey Core, and on top of that:
