Better Compatibility Checker Mod is a utility designed to improve the compatibility checking process for Minecraft servers and modpacks.
![]()
Features:
- It replaces the default Forge server compatibility checker, ensuring more accurate results when comparing modpack versions between servers and clients.
- The mod compares the modpack project ID and version ID set in a configuration file by the modpack author. It displays a green checkmark if they match or a red “X” if they don’t.
- Modpack authors can easily configure the mod by editing a file (
bcc-common.tomlfor Forge orbcc.jsonfor Fabric) to set the modpack name and version. - If the mod is not installed on the server but is present on the client, it defaults to the standard Forge implementation.
