Hi didip, glad you asked! Mattermost is an open source Slack alternative - it's got the same core features, familiar user interface, Slack-compatible integrations (so you can migrate them easily if you choose to), and more. The added benefit with self hosting is privacy, customization - and basically full control of your data. If you're curious to know who uses Mattermost, you can check out https://mattermost.com/customers/ https://mattermost.com/customers/ for some examples.
