Have you ever built a server community only for it to be ruined by one player adding in client side mods that greatly effect gameplay, such as elytra autoequip, freecam or xray? Well this mod is the one for you.
This mod only allows the mods you want to be able to connect to your server, even if they aren't loaded on the server
To use: Simply add the mod to your server, launch once, add all the client side mods/modpack to the "allowed-clientside" folder and restart, add any extra mods you want to allow to that folder as well and restart for it to take effect
Made for the Bearly Factions modpack but will work for any modpack.
Currently working on porting to fabric and updating to latest versions.
