Loaded Mods Checker

by phoupraw

Loaded Mods Checker compares the mods installed at launch with the list saved the last time a player entered a world, and reports what has gone missing.

FabricNeoForgeClient-side onlyMozilla Public License 2.0Open source1.21 – 26.1.2

What it does

When a player enters a world, the mod reads the current mod list and checks it against the previous session. Any mod that was present before and is absent now is shown, so a removed or broken jar does not go unnoticed. The check runs on the client only, and servers need nothing installed for it to work.

Fabric API is required on Fabric. The mod is published for Fabric and NeoForge across 9 release versions, 1.21 – 26.1.2, with snapshot builds included, and is released under the Mozilla Public License 2.0, so the source is open. Mod Menu and Sinytra Connector can also be added.

Key features

  1. Missing mod detection

    Mods that were installed during the last session but are no longer loaded are listed when a world is entered.

  2. Session comparison

    The mod list is stored between sessions, so each launch is compared against the previous one rather than against a fixed reference.

  3. Client-side operation

    The check runs entirely in the client, so players on a server do not need to install anything to use it.
