🔒 Privacy & Security
Your files never leave your browser! All processing happens locally on your device. No uploads to servers, no data collection.
API Usage: The tool queries Modrinth's public API to check mod compatibility. Only minimal data is sent: file hashes (SHA1) to identify mods and version queries. No personal information or modpack contents are transmitted.
📋 How it works
- Upload your .mrpack file
- Select target Minecraft version and modloader
- Click "Check" to analyze mod compatibility
- Review which mods have updates available
- Download an updated .mrpack with compatible versions
- Remember missing items to track unavailable mods for future updates
✅ What it does
- Checks Modrinth for compatible mod versions
- Shows availability for your target Minecraft version
- Handles mods, resource packs, and shader packs
- Falls back to GitHub for Fabric Carpet mod
- Preserves all other files in your modpack (configs, overrides, etc.)
- Generates updated modpacks you can download
❌ Missing Items Tracker
- Click the red ❌ button to track mods that aren't available for your target MC version
- Use "Remember missing items" after checking to save unavailable mods for future reference
- The tracker automatically checks for updates and notifies you when mods become available
- Helpful for keeping tabs on when your favorite mods get updated
⚠️ Limitations
- Only works with Modrinth .mrpack files
- Primarily tested with Fabric modpacks (other loaders may work but are less tested)
- Doesn't resolve mod dependencies automatically
- Some mods may not be available for all MC versions
Hope you enjoy!
