Ie similar to how Lemmy allows users to create instances that are federated with each other, only this Discord alternative’s instances wouldn’t federate with each other.
Instead, each instance would be a complete silo, although instance owners would be given the option to potentially federate their instance outwards (ie to other federated platforms), if they wish.
Perhaps it could potentially be forked from the already existing Lemmy?

Check out matrix there’s the synapse reference server but as someone who’s run that for a while, I wanna run some of the rust ports for it like conduwuit or tunnwul. They seem more performant over synapse. Welcome to federation, it’s a clusterfuck and it’s awesome!
