Snitch
by lizzyapp
Snitch is a NeoForge utility that scans the mods in a modpack and reports which ones pull in embedded or unwanted dependencies.
What it does
Snitch looks through the loaded mod files and flags those that carry bundled libraries or depend on other mods the pack does not expect. Its aim is to help diagnose crashes and conflicts faster by pointing to the mods behind a problem, instead of leaving the player to check each jar by hand. Because it works on jar artifacts as well as mod names, it can identify a dependency even when the mod that ships it is listed under another name.
The list of dependencies it warns about is built from what the scan finds, so a warning can point to a library that a mod embedded rather than declared. Snitch is open source under the MIT License, with its source code and issue tracker published. Files exist for NeoForge 1.21.1 only, with the 1.0.0 build dated 2026-04-21. It works on either side, and neither needs it, so it can be installed on a client, a server or both.
Key features
Embedded dependency scan
Snitch checks mod files at runtime for libraries that are bundled inside them rather than declared as dependencies.
Warnings for unwanted dependencies
A configured list of dependencies can be flagged, so that a warning appears when one of them is loaded.
Jar-level identification
Mods can be recognized by their jar artifacts, not only by their mod names, which helps when names are unclear.
Faster problem diagnosis
The output points to the mods that load a given dependency, narrowing down the source of a conflict.

Use cases
Checking a modpack
A pack author can run Snitch over a set of mods to see which ones bring in libraries the pack did not plan for.
Tracking down a crash
When a mod fails, Snitch shows which loaded mods depend on the suspected library, which narrows the search.
Who it’s for: Modpack authors and server owners who maintain NeoForge 1.21.1 packs and need to see which mods pull in extra or unwanted dependencies.

What the author says
Snitch allows you to scan all mods at runtime for embedded dependencies. Have you ever had a mod, meant to do one single thing, cause issues elsewhere, only to find it has downloaded All Of Fabric onto your Minecraft modpack? I mean, there's nothing wrong with using Fabric as a dependency, Sodium does it, Iris does…
