Atlassian, the folks behind bitbucket, jira, and (now) trello have a self hosted product: https://www.atlassian.com/software/hipchat

They also have a Slack alternative, called Stride.

And HipChat is horrible. Doesn’t even sync which multiple devices and their mobile app doesn’t support the iPhone X screen size which is a trivial update to make considering HipChat is used by some pretty massive customers. Code highlighting is still, (after years,) pretty bad.

Hipchat doesn't exactly have a stellar uptime record either.

Has anyone here used Stride? Reviews?
