MC Mod Updater & Builder

This tool helps you update your existing Minecraft mods or build a brand new mod list from scratch. It uses the Modrinth API to find the latest compatible versions and can export your list as a standard Modrinth modpack. Note: This tool only searches Modrinth - mods from CurseForge or other sources won't be found. Dependencies are automatically detected and added to ensure your modpack works properly.

How to Use:

Loader / Version: Select your desired mod loader (Fabric, Forge, NeoForge, Quilt) and target Minecraft version.

Upload Files: Drop a .mrpack file to load a modpack, or drag and drop your local .jar (mods) and .zip (resource packs, shaders) files into the upload area.

Search for New Mods: Use the search bar to find and add mods directly from Modrinth.

Process Your List: Click "Update" to find the latest compatible versions and dependencies.
