ARR-Checker is a simple Fabric mod which checks the license metadata of other mods in your Minecraft instance to make sure every single one is open-source.

If ARR-Checker finds a mod which is not open-licensed, it will print information about it to the console. That’s it! It doesn’t do anything else.

This might be useful to you if you want to create a mod-pack that only includes open-license mods.

This mod requires Fabric API which you can download HERE
