About this project

What does Mod Scanner add?

Mod Scanner

Have you ever asked yourself: "Did all my mods actually load?"

If you're a modpack creator or a player running a large list of mods, you know that feeling. The game launches, but something feels wrong.
Mod-Scanner is a simple, lightweight diagnostic tool designed to answer that one crucial question.


How It Works

Mod Scanner automatically runs when you start the game and provides a clear, simple report in its own log file. (modscanner_logs/debug.txt)

  • ✅ Scans Your /mods Folder: It checks every .jar file to see what's there.
  • 📰 Creates a Clean Log Report: It generates an easy-to-read report telling you exactly how many mods were loaded out of the total number found.
  • ❗ Pinpoints the Problem! If a mod fails to load, Mod Scanner will list the exact .jar file name in the report. No more guesswork!

Example Log Report:

Scan complete. Loaded 120 out of 125 mods from the /mods folder.
The following 1 JAR file(s) were NOT loaded:

  • some-cool-mod-1.6.9.jar
  • some-junky-mod-4.2.jar
  • another-mod-for-fabric.jar

How to Use It

  1. Install the mod and its dependency, Fabric API.
  2. Launch the game.
  3. Check the /modscanner_logs/debug.txt file inside your main Minecraft folder to see the report.

Important Notes

  • This is a client-side only mod. It does not need to be installed on a server.
  • This mod adds no in-game items or features. Its only purpose is to provide a diagnostic report.
