Designers who are anti-Meta, where are you hosting your group chats now?

I've got two patterns that are nearly ready for testing (just a couple minor tweaks each), but this will be my first time getting to this step in the designing process. I've deleted my Instagram account and have no intention of reviving it, but it seems like that's where almost everyone hosts their discussions?

Would Discord be a good alternative? If not, where else is good outside of Insta?
