self host your own voice and text chat with either Murmur or uMurmur if you don't need to let people create channels. uMurmur is so lightweight it can run on your Linux router and has excellent voice quality using Opus. The client is Mumble (desktop) or Mumla (phone).
Try uMurmur (lightweight version) out first, then shit on it.

It does not replace the gifs, one would have to upload gifs somewhere like an altchan.
It does not provide video. One would have to self host Jitsi for that. It also does not do desktop sharing. Just simple voice and text chat.
