R2Modman and thunderstore.io has grown it’s catalogue quite a bit as of late, but it’s mostly (don’t know if it’s entirely or not) unity games. It’s my favorite modding platform with features that make sharing modlists for multiplayer a breeze.

https://tcpshield.com/ they have a very generous free tier. It required spigot/bukkit plugins or a velocity plugin (velocity is a Minecraft proxy, think of this as NGINX for minecraft).
