    Slack is a communication/chat tool. Basecamp is project management.

    Twist is more organized and less intrusive and distracting than Slack. Its interface is very nice, the app is easy to use, and it's available on all the major platforms, so for me, it's the best alternative to Slack, Hangouts and Microsoft Teams.

    Nextcloud Talk, like most of Nextcloud, is very heavyweight. So if you don't have a very good server, it's going to be very slow (for me it was around 10 seconds to send a single message)
