⚠️ Please Read Before Using

Mods Optimizer will rename or move files inside your mods folder.
➡️ Make sure to keep regular backups of your modpack and server files.
While the mod includes safety checks, it cannot cover every possible edge case.

👾 Automatic Server Bundle Support

Mods Optimizer automatically disables mods that are client-only or **incompatible with servers **.
You no longer need to maintain separate client and server modpacks!

  • ✅ One modpack works for both client and server
  • 🚫 No more guesswork or duplicate maintenance

🧹 Automatic Mod Cleanup

Tired of cleaning out old versions manually?

Mods Optimizer detects and removes duplicate mod versions during startup.
This helps keep your mods folder clean and prevents version conflicts.

  • 🗑 Removes outdated mod files
  • ✅ Keeps only the latest version

🚀 How to Use the Mod

  1. Add Mods Optimizer to your modpack (client and/or server).
  2. On game or server startup, it will automatically:

    • 🔍 Scan the mods folder
    • 🔄 Classify mods by side (client/server)
    • 🧼 Remove duplicates
    • 🚫 Rename client-only mods on servers to ???.client

Tip: For best results, use this mod on both client and server.

🧵 Fabric Support?

Currently, Fabric is not supported.
Fabric does not allow mods to run after the GameProvider but before the Mod Loader, which prevents Mods Optimizer from functioning correctly.

❗ Support may be added in the future if Fabric changes this behavior.
