Description
![Mods Optimizer][logo]
# ⚠️ 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- 🗑 Removes outdated mod files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.
