Mod Better Compatibility Checker

Better Compatibility Checker, clearer modpack matching

Better Compatibility Checker is a utility mod for Minecraft Java Edition that replaces the default server compatibility check with a more reliable comparison designed for modpacks. Instead of relying only on individual mod checks, it compares the modpack project ID and version ID defined by its author.

When the client and Minecraft server use matching values, the connection screen shows a confirmation mark. Mismatches display a warning, helping players identify the correct pack version before joining. The mod supports Fabric, Forge, and NeoForge on both client and server, making modpack management clearer on BoxToPlay.
