A BepInEx configuration file syncing library. This library will help you force clients to have the same settings as the host!


  • This is NOT a standalone mod, it is intended for mod developers and does nothing on its own!
  • This does NOT edit or replace config files directly, everything is done in-memory.
  • It will NOT sync configs from mods that aren't dependent upon it.
  • CSync uses Unity Netcode's NetworkBehaviour with NetworkList to sync values.


This project is a fork of the original CSync project authored by @Owen3H.


  • A serializable, drop-in replacement for ConfigEntry: SyncedEntry
  • No seperate config file system, retains BepInEx support
  • Uses TomlTypeConverter, the same system used by BepInEx to save/load values to/from config files
  • Provides extension methods for conveniently binding SyncedEntry instances

Setup & Usage

A guide to both setting up and using CSync is available on Lethal Wiki.
