FYI what Discord calls a "server" is actually just a group of chat channels and their pool of members. The equivalent of a Discord "server" on matrix is a "Space". This blog post is a couple of years old out-of-date, but it gives you the general idea:
@strypey ist right :) matrix has a equivalent to guilds/servers.
In theory it has same functionality as discord (chat/voice/video/etc) via integration but thats lacking good ui/ux. so right now i would only see it as a chat platform with potential.
