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 - 🗑 Removes outdated mod files - ✅ Keeps only the latest version ## 🚀 How to Use the Mod 1.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. ## 🧪 Example Modpack Want to see Mods Optimizer in action?
