I explored revolt with a group of friends earlier this year, along several other solutions such as Matrix Element, Telegram and the new TeamSpeak.
Neither Revolt nor others are unfortunately at the right level of maturity to be adopted seriously. The team is doing a great job, but it’s still extremely basic.
Discord with all its warts is still the best way to have group calls in a casual setting.
We've deployed mattermost at my company because it meets most requirements that slack did minus the SSO. Surprisingly used by some big government agencies (NASA/USAF)
