About this Mod
Channel Limiter
Sometimes, when we use optimization or beautification modpacks to play on vanilla or Spigot servers, we may get kicked out of the server because some client or server mods register too many channels. This mod supply a simple way to restrict mod channel registration.
If you encounter similar situations, this mod may solve your problem.
Example

About
This mod is still in development. I'll expect to launch an available version within a few days. Until then, the in-game configuration menu will not be available.
Version?
In theory, this mod has nothing to do with the version, because the Fabric API has not changed, Mixin should also work normally, but there is no more version yet (because of the need to deal with the compatibility of dependencies). If you are in a hurry to use it, please download it and use any editor to edit mod.json, but I don't know if it will work.
Warning!
This mod DOES NOT solve your modpack channel problems, it only restricts the client from registering with the server. If you encounter this problem on a large modded server, please report it to the modpack author.
If you are absolutely sure that it is a problem with which mod and won’t interfere with it, then feel free to use this mod and use blacklist mode.
