Modins

by Xplix

Modins is a Fabric utility for copying every loaded mod into a modins subfolder at each launch, so developers and modpack makers can check what was loaded.

FabricClient-side onlyMIT LicenseOpen source1.21.1

What it does

When the game starts, Modins copies every mod that Fabric Loader has loaded into a subfolder named modins inside the mods folder. It also writes mods/modins/loaded mods.txt, a list of each mod's ID, name, version and original file path. The copies are local only: the mod does not upload or redistribute anything.

Modins is aimed at mod development and modpack work, where a clear record of the exact set of loaded mods helps when a launch behaves differently from expected. It is a lightweight tool and relies on Fabric API, which must be installed alongside it. Only Fabric Loader is required by the mod itself, and Fabric API is the named dependency it needs.

Modins is client-side only, so only the client needs it. It is open source under the MIT License, and files exist for Fabric on 1.21.1, with 1.2.0 as the latest beta release, first published and updated on 2026-08-07.

Key features

  1. Automatic mod copies

    Every mod loaded by Fabric is copied into the modins subfolder each time the game launches.

  2. Loaded mods list

    A text file lists each loaded mod with its ID, name, version and original file path.

  3. Crash investigation

    The list and copies help identify which mod is involved when a crash occurs, so a report can go to the right author.

  4. Local-only copies

    The copies stay on the local machine, and the mod does not upload or redistribute the files it collects.

Questions

Does Modins need Fabric API?

Yes. Fabric API is a required dependency and must be installed with Modins. Only Fabric Loader is required by the mod itself.

Does Modins have to be installed on the server?

No. Servers do not need it; each player installs it for their own game.

Where does Modins write its output?

Copied mods go into a subfolder named modins inside the mods folder, and the list is written to mods/modins/loaded mods.txt.
