Hi @roymeissner, I didn't check fully and as I can't see which apps are currently our slack is using. But, Rocket Chat has been extremely popular in open source projects and in the industry. Heard about it from several noteworthy people so just a suggestion. It may be interesting to look at it in the decision process. It even provides hosted solution for 500 users at Euro 50/month
Features of Rocket Chat worth considering for a great open source chat software for team:
- Video conference built in
- File sharing
- Link preview
- Integration with GitHub, GitLab, Confluence and many others.
- Native apps for Windows, Linux, Mac
- Mobile Apps for Android, iOS
My personal opinion, if SlideWiki is opensource, then go for opensource team chat to reflect the opensource in true sense (own your chat messages then handing over to third party which might have other interests some day - better privacy). I think Rocket chat provides features SlideWiki teams needs.

What makes Slack not just team chat?
