Mattermost
Mattermost is an open source, self-hosted, private cloud messaging solution compared to Slack which does not have the option to self-host. Security concerns still remain the number one barrier to a cloud computing deployment. With Mattermost, compliance is easy as the data does not leave the customer's premises. It’s perfect for businesses that want to keep their messaging app under tight control. Slack offers 2000+ integrations which covers all applications businesses use. While Mattermost has 100s of integrations as well, the use-case coverage is still limited when compared to Slack.
