Discord Alternatives, Ranked

Building an online community takes more than tools. But the right tool can make all the difference.

@mttaggart Stoat has actually moved SHOCKINGLY quickly and I would say it is easily 85%+ parity for the majority of users at this point. The biggest sticking point would probably be servers with >100 custom emojis or highly dependent on bots (which are relatively easy to port.)
@rootwyrm Last I checked the moderation tools were still nowhere near adequate, and that is a dealbreaker for me.

@mttaggart ah yeah if you manage big communities that might be a problem. For my 25 friends it doesn't really matter.
I tried it when it was still revolt and really liked it, but never actually made the move
